Rural Development Trust is now working in 1,500 villages. It has got extensive experience in all fields of rural development and building of people‚s institutions. Rural Development Trust works mostly in the areas of community health, including rural hospitals, development of disabled persons & women, education of children, environment & ecological programs, cultural activities and special programs for economic improvement of very poor families. Anantapur district is approximately the size of Aragon in Spain and has a population of almost 4,000,000. In the first 20 years of RDT‚s work not even 1% of persons affected with cleft lip & cleft palate even knew that a surgical treatment was available to correct the defect. Anantapur district like all districts in India was full of children and persons suffering with cleft lip & cleft palate, untouched by available modern techniques. With the rise in the number of plastic surgeons in India, the facility of plastic surgery became available close by to Anantapur, in a town 150 kms away. Having this facility close by, a few years ago, Rural Development Trust decided to take the challenge that, with the help of plastic surgery, there should be no child suffering from cleft lip and cleft palate in Anantapur district. From that time, we have motivated people in the village and explained them the advances in plastic surgery and that their children can have a normal life like any other child. Up till today, we have managed to get operated 200 children in this district suffering with this problem. Two years ago, we had a visit from Cirujanos Plastikos Mundi and as a result of that visit, Rural Development Trust (Fundacion Vicente Ferrer) & Cirujanos Plastikos Mundi agreed to have some collaboration between their organizations. With their visit, came the idea to have an international workshop with specialists from other countries to come to India to our hospital in Bathalapalli, Anantapur and to host a workshop especially on cleft lip and cleft palate in the field of plastic surgery. In India, international workshops are normally hosted in big specialty hospitals / hotels in big cities. This international workshop between Rural Development Trust (Fundacion Vicente Ferrer) and Cirujanos Plastikos Mundi is hosted in a rural hospital in South India. We hope this workshop will serve to improve the skills and techniques of visiting Indian plastic surgeons and we hope the visiting professors of Plastic Surgery from abroad will benefit from exchange and discussions with our Indian Surgeons. 4 1270-8597-13528 Labio leporin** 18/9/03 09:13 Página 5 First East Indian International Cleft Surgery Workshop Dr Y Bala Subbaiah Director - Hopitals Plastic Surgery is one of the fascinating branches of medical science which challenges the very verdict of nature by remodelling the shape of tissue / structure. It equally gives the same benefit to those who acquire structure abnormality due to accident or any other cause. In other words, plastic surgery can be termed as RECREATION. It gives the opportunity for an individual to RELIVE. In the context of our country, one can even say that the effects of plastic surgery are akin to REINCARNATION and allow a person to live a new life with human dignity. The above is more so true in the vast rural areas of India where many children are born with deformities they have to carry throughout the life, discriminated in many ways by society on account of those deformities. Children, particularly girls with cleft lip and palate and other such deformities are often unable to get married or lead normal lives. Not only deformities by birth but, women are often the victims of harassment in the husband‚s home, due to which they become also victims of attempted suicide by burning with kerosene, or family members conspire to kill them also by burning with kerosene. If they survive, they then become victims of discrimination on account of the horrendous injuries due to burns. The above type of cases are commonly found in rural areas and parents and the community in general have never heard of the advances in medical science and plastic surgery, which can literally change the lives of these persons. In Anantapur, in our program, which works in many different ways for the development of disabled people, we make a point to find out all children having cleft-lip / cleft-palate and it is our objective that in Anantapur district in future, there should be no child with this problem who does not receive the benefit of plastic surgery. In the last 10 years, Rural Development Trust has conducted 200 cleft lip / palate surgeries through the services of plastic surgeons in our locality. And this represents 200 children who can now have the same hopes and aspirations of any other child. In the beginning, it was not easy to explain parents that this problem of cleft lip and cleft-palate could be rectified. Many people believe that this problem is due to the fact that pregnant mothers have been exposed to the rays of the Sun during solar eclipse or due to exposure to Moonlight during lunar eclipse. Therefore, they feel that this abnormality is a curse of God and should be received as such. The main idea of this workshop is to bring together surgeons from abroad and surgeons from India who are dealing with cleft-lip, cleft-palate and other such cases 5 P R E F A C E 1270-8597-13528 Labio leporin** 18/9/03 09:13 Página 6 Cirujanos Plástikos Mundi to share their experiences. We also hope that this workshop will impart new or improved surgical techniques and skills to those who are participating in this workshop. We hope that this workshop will further help all people in both rural and urban areas who suffer from this problem to have the advantage of improved treatment from the doctors who are attending this workshop. In this context, we express our gratitude to the team members of ŒCirujanos Plástikos Mundi‚ who have travelled thousands of miles to give their valuable time and knowledge for the benefit of rural people.

Another theory is a combination of inheritance and multiple other factors. There is no genetic connection between cleft lip + palate . COUNSELING OF FAMILY 1. If a person has a cleft lip, his/her child faces a risk of 2% T 2. If a person with cleft lip already has a cleft lip child, the following child faces a risk o f 14% 3. A non cleft parent with a cleft lip child faces a risk of 4% for the following child I MORPHOGENESIS AND GENETICS O N “Failure of fusion of palatal shelves, septum, and primary palate, which normally takes place between the 8th and 17th week of embryologic development.” “The actual etiology (cause) of a cleft lip and/or palate is largely unknown, and yet at the same time we know that there are many different things that can contribute to or create a cleft. 12 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 13 First East Indian International Cleft Surgery Workshop The face and facial structures are formed out of three plates, each migrating toward a meeting point in the middle area of the face. The facial structures of the orbicularis muscle form the lip. They are joined at the philitrum lines. “If you rub your finger above your top lip, you will feel those two ridges. Those are in fact the “cleft scars” of a non cleft-affected person.” Those tissues naturally join by the fourth week of pregnancy. The palate is then formed out of the structure that begins as the tongue and palate. Between the fourth and the eighth weeks of gestation, the tongue drops down and the palatal segments then move from the sides and toward the middle, fusing in the center. I N T R O D “Run your tongue across your hard palate from side to side and you will feel the seam where the two sides fused.” A cleft, therefore, is not something that is formed, so much as it is something that does not form. Everyone began life with a cleft. For 699 out of 700 of us, the cleft fuses before birth. For that one in 700, it fails to fuse. So we are not talking about something that happens so much as something that fails to happen. U C Normal Process: T 6 weeks Maxillary process Lateral nasal process Median nasal process These three processes join and fuse to form the primary palate I Current thought is cleft will result with no mesodermal migration across site O 7 weeks Median nasal process and maxillary process have fused creating upper lip and anterior maxillary alveolus 13 N 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 14 Cirujanos Plástikos Mundi I N T 8 weeks Complex totally fused and mesodermal migration completed Tongue, which has been postured superiorly between lateral palatal shelves of maxilla, moves inferiorly allowing palatal processes to grow toward midline and fuse, form nasopalatine foramen to uvula 11 weeks Total palatal closure R O D U C T I O N Why does it fail to happen? Lots of theories, and lots of known reasons. If the tongue, for instance, fails to drop down because the baby is tucked too tightly at that critical time, the result will be a very wide, horseshoe-shaped cleft of the palate. If the blood flow to through the placenta is disrupted at a critical time, the fusion may not occur. Drugs, alcohol or medications may disrupt normal patterns of development. Or some genetic code may simply dictate that it will not happen. Women who smoke are twice as likely to give birth to a cleft-affected child. Women who ingest large quantities of Vitamin A or low quantities of folic acid are more likely to have children with cleft. A parent with a cleft has a minimum 5% chance of passing the cleft along. A parent with an autosomal dominant genetic condition that results in clefting will have a 50% chance of passing along the condition. The human embryo has a recognisable face at around eight weeks, when it measures 28mm from head to rump. At this stage the nose and lips have already been formed, probably as a result of cells migrating from the direction of the forehead and cheeks 14 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 15 First East Indian International Cleft Surgery Workshop I N T R into the face. The primary palate is formed at the end of week seven, and results from growth from the inner sides of the upper jaw towards the midline, and their subsequent fusion. Fusion proceeds from front to back and is not completed until the 11th week. The primary deformity in clefting of lip or palate occurs if this process of fusion is not completed. Cleft lip and palate occur among all races and has been recognised for many years. In the general population, i.e. from couples with no history of clefts on either side of the family, the incidence varies with populations, between 1/5000 and 1/1000 for cleft lip and/or cleft palate, and about 1/2500 for cleft palate alone. Asians are at higher risk than Caucasians or Blacks. The causes of cleft lip and palate remains unclear, although there is agreement that heredity plays a major role as a cause. The most recent surveys indicate that in some families there may be just one change in one of the units of heredity, or genes; however, cleft lip or palate in different families may be due to different changes, or mutations, in different genes that have very similar effects in the development lip. In these cases genetic risks should be reasonably easy to determine. In other families, cleft lip may be due to the combined effects of more than one gene. Possibly more than 3% of families. Lastly, animal models suggest that maternal exposure to substances that alter the normal composition of the hereditary material during the critical period of development cooperate with the genetic make up of the developing embryo in producing the cleft lip. Manifestation of the trait would depend then, not only on genetic make up, or genotype, but also on exposure to these unspecified harmful substances called mutagens. The genetics of cleft lip and/or cleft palate is complex to say the least, and an accurate clinical diagnosis is essential before giving recurrence risk figures. The first thing to be considered is that cleft palate as an isolated malformation behaves as an entity distinct from cleft lip with or without cleft palate. One line of evidence suggesting that this is the case comes from twin studies, one third to one half of identical twins are concordant, i.e. if one shows clefting the other one shows it also, although the degree of severity observed may be quite different between both twins, 15 O D U C T I O N 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 16 Cirujanos Plástikos Mundi I N T R O D U C T I O N however, one twin with cleft lip and the other with cleft palate have never been observed. A second consideration is that cleft lip, with or without cleft palate, may occur as one of a group of malformations in many syndromes of complex appearance. A syndrome is a group of small abnormalities that are often seen together in children of unusual appearance, giving them a resemblance or “family air” as it were. So cleft lip and/or palate are often associated with other abnormalities, forming part of several syndromes in a person of otherwise normal appearance fig 1). In some of the syndromes where cleft lip and/or palate are seen, the other abnormalities may be obvious and more threatening, as in the case of some chromosomal syndromes. It could be worthwhile to make here some brief comments about chromosomes. Chromosomes are like packages where the cell organises the hereditary material when it is going to divide. These packages are normally found in an even number, and can be matched in pairs, reflecting the fact that half of the hereditary material of the cell comes from the father and the other half from the mother. There are 46 chromosomes (23 pairs) in the human cells, except in the germ cells where the members of each pair have separated and are found now in “single dose”. Twenty two of these are called “autosomes”, and they contain the information for many varied traits, some of which will be noticeable in the offspring. For the purpose of identification, these chromosomes are assigned a number, from 1 to 22, so that when we refer to chromosome 6 for instance, we all know what chromosome we are talking about. The remaining chromosome is called the sex chromosome, because among other genes it contains the genes that determine the sex of the offspring. Sperm carrying the Y sex chromosome is bound to produce a male offspring, while sperm carrying the X sex chromosome will produce a female. The chromosomal syndromes are associated with abnormalities in the distribution of the chromosomes among the germ cells, so that some of these germ cells or gametes end up having more hereditary material than normal, and others less. These events, when they happen, cause very characteristic abnormalities, easy to identify, like for instance Downs syndrome. In other cases where cleft lip and/or palate is observed, the accompanying clinical features may be more subtle and could go unnoticed in a superficial examination. For instance, in Van der Woude syndrome the clefting of the palate or upper lip is accompanied by symmetrical lumps or pits on the lower lip. Van der Woude synfrome is diagnosed in the presence of 16 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 17 First East Indian International Cleft Surgery Workshop cleft lip, or cleft palate, or both, together with the lower lip pits, and it is inherited from one of the parents to the child with the probability of one in two. In some families, clefting of the secondary palate or bifid uvula are inherited following an “X-linked recessive” pattern, i.e. the problem is observed in 50% of the male offspring of unaffected couples, where the mother is in most cases the carrier. In these families, the daughters are hardly ever affected, but 50% of them on average are carriers. In one of these families from Iceland the single gene has been mapped to the long arm of chromosome X. In its “pure form”, i.e. unaccompanied by any other malformation (the so called non-syndromic cleft lip with or without cleft palate) it appears to be an autosome; dominant in some families, where it has been located on the short arm of chromosome 6. Other pedigrees show an autosome; recessive pattern of inheritance, not mapped so far. A detailed family history may help to establish the mode of segregation, and hence the recurrence risk factor. However, most families may not show a pedigree congruent with the autosomal dominant model, and if other diagnoses have been excluded, it would be proper to quote recurrence risk figures based on empirical data compatible with a multifactorial model. The following table, compiled by Peter harper, may be useful in these cases. I N T R O GENETIC RISKS IN CLEFT LIP AND PALATE RELATIONSHIP TO INDEX CASE Siblings (overall risk) Siblings (no other affected) Siblings (2 affected siblings) Siblings & affected parents Children Second degree relatives Third degree relatives General population CLEFT LIP/PALATE CLEFT PALATE 4.00% 2.20% 10.00% 10.00% 4.30% 0.60% 0.30% 0.10% 1.80% — 8.00% — 6.20% — — 0.04% Notice that if it can be established that there are no other affected relatives, the risk to siblings (2.2%) is less than the overall risk (4%). The higher figure should be used if the history is unreliable or unavailable. From a subjective point of view, it is essential to emphasize that cleft lip occurs as an accident of nature, and not through any fault of any of the parents.. We can not but speculate on the reasons why the genetics of cleft lip and palate are so frustrating. It could well be that we are looking at the wrong trait, that is to say, at a trait that is too far removed from the error in the development of the embryo. There are many processes which could play a role in the formation of the lip, and each of these requires different key molecules to be made normally. Many genetic mutations could alter the function of any of these molecules, and any of these could lead to cleft lip. This model would explain the high incidence of cleft lip and the low recurrence in the same family. But several other models are possible. 17 D U C T I O N 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 18 Cirujanos Plástikos Mundi I N In brief, when counselling a family with cleft lip and palate it is essential to ascertain whether this is the only malformation (non-syndromic cleft lip) by examining the patient in minute detail. Then a careful family history should be taken to ascertain whether there is a recognisable pattern of segregation, i.e. whether it can be said that in a particular family the clefting is inherited as a sex-linked or an autosomal trait, etc., and if all of these have been excluded the figures given in the table above could be mentioned. The therapeutic requirements and possibilities should be mentioned in the same session, if possible with illustration of real life corrections.

In this regard, the pathogenesis of hypoxia-induced cleft lip and palate has been extensively studied,1 with the most vulnerable aspect of craniofacial development related to hypoxia appearing to be the morphogenetic 21 I O N 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 22 Cirujanos Plástikos Mundi I N T R O D U C T I O N movements of facial prominences. On this premise, it may be postulated that a metabolic impairment in the facial mesenchyma might be the cause of the failure of mesenchymal reinforcement of the facial processes in cleft lip and palate fetuses. In a recent study, 2 to better evaluate the role of a possible topical metabolic alteration in the pathogenesis of cleft lip, we have histochemically and ultrastructurally evaluated mitochondrial functionality in the orbicularis oris muscle obtained from unilateral cleft lip patients. Our findings, while consistent with evidence excluding an inherent myopathy of orbicularis oris muscle, evinced both an increased oxidative metabolism and pathologic aggregates of glycogen and mitochondria. On this premise, it is intriguing to speculate that enzymic anomalies, reflecting the above-mentioned local metabolic impairment, might be detected in the amniotic fluid in the presence of fetal cleft lip and palate. Indeed, it has been recently confirmed in a rat model that several enzymic anomalies may be detected in the amniotic fluid of cleft palate fetuses.3 Aims of this study were to evaluate whether it is possible to determine, by means of isoelectric focusing, an enzymic differentiation in human amniotic fluid and whether the onset of fetal cleft lip and palate is accompanied by a pathologic enzymatic differentiation pattern in amniotic fluid (Fetal Unilateral Cleft Lip and Palate: Detection of Enzymic Anomalies in the Amniotic Fluid Edoardo Raposio, M.D., Ph.D., F.I.C.S.; Paola Panarese, M.D.; PierLuigi Santi, M.D. PLASTIC & RECONSTRUCTIVE SURGERY 1999;103:391-394) • Infections (rubella, toxoplasmosis) • Growth hormone deficiency • Drugs and vitamins – Low levels of FOLIC ACID has definitely been linked with causing cleft lip and palate. Cleft lip and/or cleft palate occurs in the developing fetus between the 4th and 8th week. After it happens, nothing can change it. There is a new nationwide (U.S.) push to increase folic acid intake to prevent birth defects. Low folic acid levels cause other birth defects as well. Since January 1, 1998, most grain products, including brad, pasta, flour and rice, will be fortified with folic acid, a B vitamin that reduces the risk of spina bifida, . . [listing several others]. (because of a new FDA ruling) 22 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 23 First East Indian International Cleft Surgery Workshop Women of reproductive age are advised to consume at least 400 micrograms of folic acid daily. Foods naturally rich in folic acid include leafy dark green vegetables, citrus fruits and juices, kidney and lima beans, and liver. It is important to also take a daily multivitamin-mineral pill containing at least .4 milligrams of folic acid. – Women who take excessive amounts of vitamin A early in pregnancy can cause serious birth defects in their unborn children, according to a Boston University School of Medicine study. Researchers found that the babies of women who daily consumed more than 10,000 international units (IUs) of vitamin A from supplements (nearly four times the recommended amount) were more likely to be born with malformations of the head, face, heart and brain. In addition to supplements, vitamin A is found in most animal foods and especially large amounts in liver. A three-ounce serving, for example, may have more than 30,000 IUs. Even if women took no supplements, those who frequently ate liver could exceed safe vitamin-A levels. Beta carotene, which the body can convert into vitamin A, is not associated with an increased birth-defect risk. When taken correctly during pregnancy, vitamin A is an essential nutrient in the baby’s development. But several national surveys suggest that two to five percent of women of childbearing age may be consuming more than 10,000 IUs daily. Given the Boston University study’s findings, co-author Lynn L. Moore recommends that these women consult with their physicians before taking vitamin-A supplements exceeding 8000 IUs • • • • • Steroids Diazepam Aminopterin Anticonvulsants (- incidence 10X) Smokers (2X incidence) I N T R O D U C CLASSIFICATION AND RECORDS CRANIOFACIAL ANOMALIES T Cleft Types (Veau) Cleft Lip = the severity of cleft lip can range from microform (very small defect) to complete clefts, and be unilateral or bilateral. • Cleft lip will usually result in minor deformity of the nose characterized by a flattened nostril on the affected side and flaring of the base on the affected side. • Cleft lip can involve the alveolus, in which case it has involved the primary palate. 23 I O N 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 24 Cirujanos Plástikos Mundi I N T R O D U • If there is a bilateral cleft of the lip, there may be extension of the premaxillary segment. • Cleft palate can occur with cleft lip or less often by itself. • Some patients will present with submucous clefts where the mucosal lining of the oral cavity roof is present without appropriate supportive bone and muscle structure. • Signs of submucous clefting include a bifid uvula, diastasis of soft palate musculature (division of muscles along midline), and notch in hard palate.

Early surgery, before one year of age, gives better speech results. No additional risk of growth disturbance has been proven with surgery at an early age. The inhibited growth of the middle face is mainly a consequence of lip and palate surgery. Minor disturbance is inherent in the cleft. In a child, this inhibited growth is masked and the full truth will not be learnt until your patient reaches adult age. Tight lips, aggressive undermining and handling of tissues, and early bone grafting will contribute to disturbance of circulation and scarring, leading to diminished growth. Growth disturbance due to lip and palate surgery produces pseudoprognatism, dishface . No single method of palate closure has proven to give the ideal combination of good speech and growth. A more important factor is the technique of the individual surgeon. Be gentle! The lip can be operated at any time between 3 months and 90 years!. However, the psychological trauma of growing up with a cleft makes early surgery desirable. Also, correction of the distorted nose in a unilateral cleft is best done together with the lip; it will not be detrimental to growth. The chance of correction will otherwise be missed. Patients DO NOT USUALLY come back in developing countries. We have to do as much as we can. Normally start with the lip surgery, then palate. Doing both in one session will pose an added risk in a child that is often not in optimal condition anyhow. (sometimes both operations are done in one session see the Mexican operation) Closing the lip and creating continuity of muscle will mould the alveolar cleft of the hard palate and make anterior palate closure easier. Palatal closure in a child older than 2 years is difficult: hard tissues, no muscles functions… He won’t speak intelligibly with his palate, and leakage of food and fluids to the nose is present. (see Dr. Jobe’s lecture) 26 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 27 First East Indian International Cleft Surgery Workshop PREOPERATIVE CONSIDERATIONS AND EXAMINATIONS Only operate when: > 10 HB > 10 weeks old > 10 pounds* I N (Randall advocated repair in first ten days of life, as soon as health permitted) Do not operate: • an anemic child, • a malnourished child, or a child with upper respiratory tract infection, which is more common in these children. • Listen to the lungs and check temperature!!! Look in the ears and throat. And remember: T R “The surgery of cleft lip and palate is elective” FEEDING OF CLEFT PALATE CHILDREN A cleft palate child in a developing country is often malnourished. The mother needs advice and training to feed it properly and maintain hygiene. Mortality is high among cleft palate infants. O D Fluid Intake Needed to Prevent Dehydration after and before surgery • Bottle feed with a regular nipple. Enlarge nipple hole and remove one corner of cross cut area. • Remove bottle after 1-2 swallows so as not to overfill the oral cavity. • Feeding takes longer and demands understanding and cleanliness. Breast feeding is only sufficient for two weeks. After this, expressing milk and supplement is necessary. Spoon feeding is an alternative to bottle feeding. It is often necessary to admit the mother and the child until the feeding problem has been solved and weight gain is satisfactory. A child with double cleft lip and palate is especially vulnerable. Check weigh gain: + - 8 ounces a week. * Fluid and Weight Measurement Conversions: To convert weight (kg) or fluid (cc or ml) to pounds or ounces, use the following formulas. To convert Kilograms to pounds: Multiply by 2.205 - 10 kg = 10 x 2.205 = 22.05 lbs. cc’s stands for cubic centimeters. ml’s stands for milliliters One cc = one ml They are equivalent. One teaspoon = 5 cc = 5 ml One Tablespoon (Tbl) = 15 cc = 15 ml One Tablespoon = 3 teaspoons One ounce = 30 cc = 30 ml = 2 Tablespoons = 6 teaspoons 8 ounces (The common size for a formula bottle) = 240 cc = 240 ml 27 U C T I O N 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 28 Cirujanos Plástikos Mundi I N After surgery, our babies go on something of a hunger strike. They refuse any fluid intake at all. Dehydration becomes a concern, and often times, a striking baby ends up back in the hospital for IV rehydration. The basic formula use for essential or “maintenance” fluids are the following: 4 cc/hr/kg for each of the first 10 kg 2 cc/hr/kg for each kg between 10 and 20 kg 1 cc/hr/kg for each kg above 20 kg T This is actually an IV dosing schedule, but it would be applicable to oral intake as well. Any fever or other reason to lose fluid (drains, bleeding, etc) can GREATLY increase the amounts stated above. R One ounce of water is about 28 cubic centimeters (cc); 1 Kg is about 2.2 pounds. Thus a baby who is 10 Kilograms is about a 22,5 pound baby. So the baby would need: 4cc x 10 kg or 40 cc of fluids. O D U WATCH OUT FOR DIARRHEA, VOMITING, FEVER, EXCESSIVE SWEATING, AND ANY OTHER CONDITION THAT WILL DRAW OFF MORE THAN THE NORMAL AMOUNT OF FLUID. IN THOSE CASES, FLUID INTAKE MUST INCREASE! TEN WAYS TO ENHANCE YOUR CHILD’S SELF-IMAGE 1 Do not allow your child’s craniofacial condition to define him as an individual. C “My son has a cleft”. But he also has bright, sparkling eyes, a winsome personality, an active imagination, and many more attributes. Some parents actually refer to their child as “a cleft”. In reality, you have “a child”, and your child has a cleft. T 2 Love your child unconditionally. Do not allow your child to think that your love I is dependent on anything he or she has done or can do. Do not let your child think that love is dependent upon personal beauty. If a child feels that your love is dependent on something, then losing that something can, in your child’s mind, make you stop loving him or her. 3 Cultivate a home environment in which each person’s worth as an individual is O affirmed. Share feelings, experiences, etc. Enjoy life together as a whole family unit. 4 Help children to experience good feelings about themselves. Instead of saying, “I N feel so proud of you for that.” say, “Do you feel proud of yourself for that?” or “How does that make you feel?” 28 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 29 First East Indian International Cleft Surgery Workshop 5 Provide a good example. Children must feel that it is not conceited to feel good about themselves. Let your child know that you, in fact, feel good about who you are. That gives him permission to feel good about who he is. 6 Cultivate friendships with many diverse people. Your child must be given the opportunity to experience the notion that there is not a very narrow focus of what is “acceptable”. The people in your child’s life should portray the rich diversity that is available to us in this big, wonderful world. In recognizing a wider band of what is “acceptable and positive”, your child will be more likely to find himself within that band. I N T 7 Be aware of and tone down your own attitudes based on “looks-ism”. Do you often point out people who are “good looking”, or who have flawless bodies? Do you make negative comments about persons who are not beautiful? Do you comment on the physical beauty of TV or movie personalities? Every time you do that in your child’s presence, you are, in effect, saying to your child, “Physical perfection is all that matters in this world”. R O 8 Always point out positive attributes about others that do not involve the physical. Rather than identifying people by race, hair color, height, weight, etc, try finding some other way to describe a person. Maybe a person can be defined by something he or she has done, or by some personality trait, or by a particular talent. D 9 Encourage your child’s autonomy. Give your child the freedom to make appropriate decisions, take appropriate risks, and foster a sense of competency. Let your child’s own accomplishments give him a sense of worth and personal value. U 10 Join a support group. Let your child know that he or she is not the only child in C the world who was born with a craniofacial condition, and that others with the same condition are lovable, likable people as well. A support group will also give your child access to kindred spirits with whom he or she may discuss some of the issues that only another who has “been there” can truly understand.

In addition, local anesthesia allows the anesthesiologist to keep the patient ‘lighter’ during surgery. Always alert anesthesiologist before injecting ‘jungle juice’ (adrenaline). Inject with a small needle to distribute the solution evenly. Inject and then wait 5 minutes by the clock to get maximal vasoconstrition. It is advantageous to mix your own solution as ready mixed lidocaine with adrenaline are often outdated or have been stored at too high a temperature. RECIPE JUNGLE-JUICE 80 ml normal saline 20 ml lidocaine 1% 0,5 ml 1:1000 adrenaline ——————————— 100 ml 1:200 000 adrenaline 0,2% lidocaine After preparing it, divide the 100 ml jungle juice into several containers, one for each patient. Beware of AIDS HIV. When used together with halothane, the maximum dose of adrenaline is 5 - 10 microgram/kg. This corresponds to 1-2 ml/kg when jungle juice is used. A 3kg child can have only 3-6 ml of jungle juice. Insufficient ventilation and a high PaCO2 lowers threshold of arrythmia. In grown ups, jungle juice gives sufficient anesthesia to be able to operate without using general anesthesia. If you are a beginner, start your surgery on grown ups with 31 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 32 Cirujanos Plástikos Mundi P R E L I M I N A R I E S T O C L E F T S U R G E R Y incomplete unilateral lips. Bilateral cleft lips always bleed more. When your lip surgery is fast and secure and you are able to control bleeding it is possible to operate cleft lips under ketamine anesthesia. KETAMINE ANESTHESIA The child be positioned with a pillow under the shoulders. The neck should be extended. The operator uses hands to advance mandible and keep airway free in between. Suction is used freery to crear airway from blood and mucous. Premedicate with valium and atropine 1/2 hour pre-op. Ketamine is given 5-10 mg/kg bodyweight in a single intramuscular injection; 1/2 of this dose could be repeated after 30 minutes. Intubation should be available. Mouth to mouth breathing always is. It is better to perform ketamine surgery from 6 months of age as ketamine often gives insufficient anesthesia in smaller babies and even a maximum dose leaves you with a very mobile patient. With increasing age ewen lower doses 2,5-5 mg/kg body weight is sufficient to give relaxation. Valium can be repeated at the end of surgery, which should not exceed 45 minutes. The risk is apnea and a taped stethoscope should be used to monitor the child. GENERAL ANESTHESIA Cleft palate surgery should be performed only with endotracheal intubation. Cleft palate surgery or lip surgery with intubation can only be performed when you have an experienced anesthesiologist and proper equipment: tubes of all sizes 3 - 3,5 - 4 4,5 - 5 - 5,5 - 6 precurved are used. Refer to figure 9. Use a circuit with limited dead space when dealing with infants. Cleft palate surgery is elective and should not be performed if these conditions are not met. 32 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 33 First East Indian International Cleft Surgery Workshop Patients of all ages are operated. The older patient often has teeth. Padding between the teeth and tube in the form of a gauze help to keep the airway open. Gauze or packing mixed with some lidocaine kept to prevent leakage from tube and to collect blood and mucous shold be kept long and protrude outside the oral opening. Forgotten gauzes have caused deaths in palate surgery. Postoperative, a long tied suture through the tip of the tongue can help to keep a free airway. The surgeon should not leave the theatre until patient breathes properly. Possible airway problems that may occur during surgery are clogging of the tube by mucous, tube into one bronchus, dislocation of tube, or tube in oesophagus. The surgeon sould observe and report if blood gets darker. Watch out for hypothermia. Cover patient properly in cold room.

A back cut should be made on lateral side after freeing mucosa from maxilla. Incise mucosa in the buccal sulcus up to the opening of the parotid duct. This incision is necessary in complete and incomplete clefts. Make this back cut in front of the opening of parotid duct. Make a large back cut in a wide cleft lip. In incomplete lips, this incision and saving of M and L is not ALWAYS necessary. Cut line from points 9 to 10 from inside of lip, saving as much muscle as possible. Free the lateral element from maxilla point 9 to 10 in a complete cleft. Pack this area with wet gauze. Clamp bleeders. Tie or sizzle larger ones..

O S U Principles : 1. Palatoplasty is a given techniche 2. Complete closure of the entire palate cleft in a single operation if possible 3. Construction of an adequate functioning soft palate. Soft palate is incised to produce three distinct layers: nasal, oral mucosa, and muscle 71 R E 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 72 Cirujanos Plástikos Mundi P A L A T E Rules in any palatoplasty : 1. Should be performed at early age (6/18 months). Bardach and Salyer recommend when the soft palate is only affected it can be performed at 10/12 months (always possible to close the cleft without leaving bare bone exposed) 2. Single stage Two- flaps palatoplasty is the surgery of choice (with all the differents variations). 3. Two-layers closure of the entire hard palate with approximation of the oral and nasal layers to avoid dead space between them, securing the position of the mucoperiosteal flaps on the oral side. 4. Complete closure of the anterior palate to prevent oronasal fistulas. 5. The muscles of both sides must be dissected from the posterior edge of the hard palate and from the nasal periosteum, reoriented, suturing together creating a functional muscle sling 6. Approximation of mucoperiosteal flaps on the oral nasal side must be achieved without tension. The amount of bone exposed lateral to the mucoperiosteal flaps must be equal to or greater the witdh of the palatal cleft to achieve tension-free closure. Method: We have selected, two procedures will be presented: 1. Cleft of the soft palate 2. Cleft of the soft and Hard palate C 1-A Cleft of the soft palate L O S You need good light and suction. Make medial incision of soft palate slightly towards oral side. • Incisions are carried along a line between the oral and nasal mucosa: Nasal mucosa is darker red • Exposure of the soft palate musculature (avoid deep incisions into the muscle) • Lateral incisions start 1 to 1.5 cm posterior to the maxillary tuberosity. They are anterior (tuberosity) and medial (alveolar process Steps U R E 1. 2. 3. 4. 5. Incisions design Raising the mucoperiosteal flaps Left V-shaped area in the hard palate is left intact.

L Superiorly based pharyngeal flap O Indication S The indication for a pharyngeal flap in a civilized setting would be nasal escape as diagnosed by the speech therapist. In the “bush”, a wide cleft palate in an older child or grown up might be an indication for a primary pharyngeal flap during palatal closure. Repaired patients that come back due to nasal speech is of course another indication for a pharyngeal flap. U R E 78 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 79 First East Indian International Cleft Surgery Workshop PHARYNGEAL FLAP-PUSHBACK PROCEDURE BY P DR. RICHARD JOBE M.D. A Perhaps 35 years ago when he was at Yale and I was starting a practice in Palo Alto, Bob Chase and I were discussing a problem patient of mine over the phone, and we came up with what we though was a marvellous idea – the pharyngeal flap-pushback procedure. We did the procedure a few times on each side of the country. He moved to Stanford and we asked David Dibell, then a resident, to put together a paper describing our great idea. In the research for a second paper giving results for many more patients, it was found that C.A. Honig of the Netherlands had described the procedure in a thesis and properly credited it to Sanvanero-Roseill, in Italy, who had presented the idea at a meeting in 1954. We learned again to be careful about claiming credit. Good minds often come up with the same good ideas when faced with the same problems. Since that time, Chase has become a hand surgeon, a medical educator (which he always was), and an anatomist and I have continued to use the Pharyngeal FlapPushback procedure4,5 when faced with patients who had mobile palates and the need for a pharyngeal flap. The Cleft Palate Clinic (now Craniofacial Clinic) at Stanford has never had a good data base. One is currently in development. As a result, a careful statistical analysis of our results is not possible. The high frequency with which patients have stopped having linguistic problems after the surgical procedure has led us to continue our work without seeking alternative techniques, although more recently I have become an enthusiast for Leonard Furlow’s double opposing Z-plasty, and, where appropriate, I have added that technique to reduce the circumference of the velopharyngeal sphincter, to elongate the soft palate, and rearrange the muscles to a more normal posture and function. The procedure of pushback with pharyngeal has been very effective in treating a broad range of patients with velopharyngeal insufficiency (VPI) according to my own experiences and those of other surgeons. The pharyngeal flap, which is put into the nasal pushback raw area between the hard palate and the soft palate to keep the velum from being pulled forward by scar contraction, is not expected to serve as an obturator and should not block soft palate motion. Postoperative airway obstructive problems have been encountered much less frequently than after standard pharyngeal flaps. The operation should not be done for a patients with a paralyzed palate. The procedure, which is not difficult to perform, is described below. L A T E C L O S Evaluation In patients with velopharyngeal incompetence, in addition to the usual historical and physical examination and appraisal of the prognosis by a speech-language pathologist, the dynamic potential of the palate should be determined by more objective means such as videofluoroscopic voice studies and nasopharyngoscopy. The operation depends more on intrinsic palage motion than a pharyngeal falp procedure that is designed primarily to obstruct the velopharynx in which valving depends on motion of the lateral pharyngeal walls. 79 U R E 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 80 Cirujanos Plástikos Mundi P A L A T E C L O S U R E The procedure With Dingman or Dott gag in place and the patient under oral endotracheal anesthesia, the palate and posterior pharynx are infiltrated with 0.5% lidocaine containing l/200,000 epinephrine. A pharyngeal flap is designed using approximately 80% of the width of the posterior pharynx, extending up to a base at the top of the nasopharynx. It is a little over 4cm long, perhaps lcm longer than the distance from the posterior pharynx to the back of the hard palate. The longitudinal incisions are first made with a knife and then deepened through the transverse fibers of the superior constrictor to the prevertebral fascia with a blunt scissor, such as a Metzenbaum. The flap is then elevated from the fascia by spreading the tissue with a right angle scissors or clamp. When the flap has been elevated throughout its length, it is divided inferiorly with the right angle scissor. The flap is then elevated to the base of the skull, and bleeding is controlled in the donor area. A suture through the tip of the flap, left long, will assist in retrieving the flap later. It is wise to elevate the flap before doing anything more than injecting the palate, so that blood from the palate will not obscure the development of the flap. The donor area need not be closed. Once the flap has been developed, if any surgical correction of the soft palate is planned, it should then be done, before the pushback, because it is easier to dissect the soft palate when it is stable. In recent years, I have often done a Furlow Z-plasty palate repair as an accompaniment to the pushback-pharyngeal flap procedure to enhance the opportunity for significant improvement of the velopharyngeal incompetence. The soft palate closure then is best postponed until the pushback is completed and the pharyngeal flap attached, because insetting the flap into the pushback defect is easier through the open palate. Hard palate flaps are then raised. By now, the epinephrine can be expected to have done its work. Dorrance flaps are used for incomplete clefts (Fig. 1), and Wardill flaps for complete clefts (Fig. 2). The flaps are elevated posteriorly until the nasal mucosa and muscle and/or palatal aponeurosis can be divided from the hard palate and the soft palate pushed away. The pushback is aided by fracture of the hamulus or release of the tensor tendon, stretching the greater palatine vessels, and lateral dissection into the space of Ernst. The back of the palatine foramen can be resected with an osteotome, if desired, although this is not often necessary to achieve and adequate pushback. A centimeter of posterior displacement is not unusual. Fig 1. Placement of the pharyngeal flap in combination with a Dorrance pushback. (A) Palatal incision. (B) Suturing the flap into the raw area created by the pushback. (C) Central through-and-through sutures hold the pharyngeal flap in place, lateral sutures maintain mucoperiosteal flaps in pushed back position. (D) Lateral view of completed operation. Note that flap covers raw area between back of bony palate and front of soft palate, not the top of soft palate. Reprinted with persimission. Unless something is done to maintain the retrodisplacement of the soft palate, it will be lost to scar contracture in the healing process. Therefore, the pharyngeal flap is then brought forward, over the dorsum of the velum through the defect of the pushback, from the nasopharynx to the dorsal side of the hard palate mucoperiosteum, which has been elevated and set back. If the soft palate has been opened, it is easy to maneuver the pharyngeal flap into this position. If it has not, pass a small Robinson catheter into the nasopharynx through the opening at the 80 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 81 First East Indian International Cleft Surgery Workshop back of the hard palate beneath the elevated hard palate mucoperiosteum (Fig. 3).4 The end of the catheter is then retrieved from the pharynx and a suture, which has been put into the tip of the pharyngeal flap, is passed through the holes in the catheter. Withdrawing the catheter will bring the end of the pharyngeal flap into contact with the underside of the retroposed hard palate mucoperiosteum where it is secured by at least 3 sutures through the hard palate mucosa, in and out through the flap, snubbing it against the overlying mucoperiosteum and back through the palate mucosa, and tied in the mouth. Be certain that the flap has been advanced sufficiently such that there is ample contact between the flap and the pushed-back hard palate mucoperiosteum. This contact is often assisted by additional sutures, placed to spread out the pharyngeal flap by suturing the corners of the flap to the underside of the elevated hard palate mucosa. Chromic sutures (4-0) are used in anchoring the flap. At this point, the Wardill or Dorrance flaps may appear to be free, flapping from the roof of the mouth. The tongue will soon correct this problem, but nurses and parents are less concerned if several sutures are placed loosely to keep the flaps up against the palatal bone. If the soft palate has been opened, it should now be repaired, and the wounds should be carefully inspected to control any bleeding, which concludes the operation. At the end of the procedure, the mouth is rinsed with the lidocaine/adrenalin solution to reduce immediate postoperative pain. P A L A T E Postoperative After the procedure, there will be some blood staining of the saliva, which is likely to drain externally more than expected in palate surgery because swallowing is apparently quite uncomfortable at first. Usually on the day after surgery, the saliva is clear and swallowing is easier. It may be a couple of days before the patient can take enough fluid to stop the intravenous feeding, and be discharged. A stiff, painful neck can be expected for a few days because of the proximity of the surgery to the cervical spine. Otherwise, the early postoperative course is similar to other palate surgery. It usually takes more than 2 weeks for all the wounds to heal. I require a liquid or pureed diet for 3 weeks. The hypernasality that justified the surgery is frequently replaced by denasality while postoperative swelling is present. This denasality will disappear, and some of the hyernasality will return after the swelling goes down. The occasional happy result is the permanent loss of hypernasality, but more frequently some therapy is necessary. The results of our x-ray studies have shown the palate to be thick and stiff up to a year after surgery, so we believe that it is not desirable to start early speech therapy, because we expect that there will be better progress after the palate is a bit more flexible C L O S U Combining the pharyngeal flap push back with primary palate repair We know that patients who have had palate repair after the development of speech have a more difficult time correcting the hypernasality. Therefore, I have usually done a pharyngeal flap/pushback along with the palate repair in older patients. I 81 R E 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 82 Cirujanos Plástikos Mundi P A L A have used this combined procedure most frequently in the third world, where followup is difficult, and where speech therapy is often unavailable. In the few circumstances where I have performed this procedure in the United States, it has seemed justified. I recall a 5-year old girl who had a flap constructed during her palate repair. She had no suggestion of cleft palate speech immediately after the wounds had healed. Complications The usual litany of complications in palate surgery apply. I can recall only one occasion where it was necessary to take a patient back to surgery for bleeding. I know of no deaths, and I have not seen patients harmed or their speech worsened as a consequence of this procedure. T Contraindications E This operation should not be done on patients who have no motion in the soft palate. Better results can be expected if, on videofluoroscopy, velar motion is appropriate in direction and timing during speech. Clinical impression C L O S U R Having done this operation more than 200 times, I believe that it can solve the problem of hypernasal speech in any child who is intelligent and has appropriate motion on videofluoroscopy. Having become an enthusiast for Furlow’s Z-plasty () that reduces the velopharyngeal diameter and circumference, corrects the muscle abnormality, and lengthens the palate, and supported by recent reports of successful correction of VPI after palate repair by this operation alone,7,8,9 I believe that I would probably limit the use of the pharyngeal flap/pushback operation to those who have failed after the Z-plasty, to those with gaps on videofluoroscopy in excess of 4 mm, and particularly to those whose palates are centrally scarred and shortened by surgery and its complications.

The palate must be long enough to reach the back of the throat to close off the nose. It must be mobile enough to do this quickly and intermittently for correct function. Sometimes a normal appearing palate lacks function as well. Some of these normal looking palates are intact but have poor muscle positions. Others have palates too short to reach across a large nasopharynx. Function can also be impaired after adenoids have been removed, making the nasopharynx too large for the palate to reach. Neurologic defects can also limit palate motion. Often failure is a matter of lack of speech correction. We must be certain that this is not the case before suggesting surgical correction. Where available, it is common practice to send patients for a course of speech therapy, before advising surgery. However, this is not necessary if the palate is clearly too short or moves poorly. There are sophisticated ways to measure the function of the palate using flouroscopy during speech and nasopharyngoscopy. A less sophisticated and easy approach can also be to see if a patient can be taught to blow out of the mouth without air escaping through the nose. If this is not possible, poor palate function might well be the cause. There are surgical procedures to correct these deficiencies. Surgically the deficiencies are: palate too short nasopharynx too large poor muscle structure in the palate immobile palate from deficient innervation failure of previous surgery. 89 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 90 Cirujanos Plástikos Mundi The surgeon must select the best operation for the problem the patient presents. Surgical corrections L The first three of the following methods leave the palate looking relatively normal and depend upon enhancing normal function. The palate may be lengthened by use of a Z plasty or with a “push back” procedure. E The palate can be opened as in repairing a cleft and the abnormally placed muscles rearranged. This is done in th e correction of a submucous cleft palate The nasopharynx can be reduced in depth by placing an implant or cartilage graft behind the nasopharyngeal mucosa. C T U R E S In the more severe deficiencies abnormal situations are created which compensate for the difficulty. The most common of these is a pharyngeal flap in which a vertical flap of the posterior pharyngeal mucosa is attached to the back of the palate. This partially obstructs the nasopharynx, reducing nasal escape, and divides the nasopharynx into two spaces allowing the lateral pharyngeal musculature to help close the nasopharynx. These can be narrow or wide. Wider flaps are particularly useful where limited palate motion pre-exists. There are a number of varieties of pharyngeal flap operations. For active palates,The author prefers a superiorly based flap that holds the palate back done at the same time as a push back procedure to lengthen the palate. This flap is high enough to allow normal palate movement below it. For relatively inactive palates the flaps should be wider and partially obstruct the nasopharynx. Another popular approach is the pharyngoplasty which reduces the size of the nasopharyngeal opening by taking flaps of muscle and mucosa from the sides of the nasopharynx and turning them across the back of the nasopharynx. This creates a bulge on the back of the nasopharynx, and the closure of the areas from which the flaps were taken reduces the size of the orifice. The result is a much smaller orifice which is closed appropriately by the rearranged muscles. Patients who have had these procedures are generally significantly improved. They will still have the abnormal speech mechanisms habituated and will require further speech training. The surgical corrections make such training much easier and more effective. 90 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 91 First East Indian International Cleft Surgery Workshop L Dra. Andrea Jobe Executive Director and Director of Speech Programs / RSF-EARTHSPEAK REHABILITATION IN PATIENTS WITH CLEFT PALATE SPEECH E C Three Major Factors in the Rehabilitation of Cleft Palate Speech The rehabilitation of cleft palate speech ideally requires an integrated, team approach incorporating the professional efforts of: • plastic and reconstructive surgery • speech and language pathology • dentististry and orthodontia The impact a cleft palate has upon speech production cannot be overstated. A number of the major organs of speech have interrupted function due to this deformity. Even with surgical correction, speech may not proceed normally without therapeutic help. If surgical correction of the cleft lip and/or palate is done before 1 year of age, there is a good likelihood that speech development will be normal. However, if such correction occurs after 1 year of age or the age of speech onset, a significant number of children may still require speech therapy in order to overcome their incorrect method of sound production. Even with children who have had cleft lip and palate repair before the onset of speech, as many as 25% of them may have the need for some speech therapy Historically, such correction has been problematic in developing nations. There are many reasons for this: economic, geographical and availability of speech therapy services. The conventional methods of speech therapy require that an individual be brought to the professional’s office 2 to 3 times a week for individual or group lessons that can last up to 1 hour. The fee can be high for such service where it is available. 91 T U R E S 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 92 Cirujanos Plástikos Mundi Poor teeth alignment or missing teeth due to complete cleft lip and palate can also contribute to the speech problem L E C For the past 18 years, a method to provide speech correction for cleft palate speech to patients who have no access to speech therapy has been sought by the individuals of RSF-EARTHSPEAK. Exploration of ways that dental and orthodontic assistance can be brought to these individuals is also being done. Over the years a method called Corrective Babbling has been developed. This method is delivered through educating parents and caregivers to become the speech teachers their children need. This bypasses the geographical, economic and availability barriers that currently exist. Corrective Babbling is a scientifically based approach that uses what we know about the organs of speech, speech sound production, developmental stages of speech learning, speech teaching and how the problems of cleft lip and palate challenge normal speech development. How Speech is effected by a Cleft Palate There are no special organs devoted to speech in mankind. Organs that are used for respiration and eating are adapted for speech use. T U R Shortly after birth, children begin to use the organs of respiration and eating to learn the speech sounds of their native language. This process begins at birth with the first cry, proceeds through stages of “cooing” and proceeds on to babbling. Crying begins the development of oral and nasal airflow distinction. Cooing forms the motor basis for learning the vowel sounds and babbling teaches the consonants and vowel combinations that later form words. This development proceeds and intensifies until the child is about 1 year of age. At this time, the stored soundmotor patterns will then be further refined and employed in word development as expressive language begins. The developing child first learns the sounds of his native language by observing sounds that he sees, feels and hears. He is constantly bathed in an environment of these sounds as his mother and others “talk” to him E Child— Sees Feels Hear About 4 months of age the developing child begins to try to imitate the sounds that he has seen, felt and heard using his own organs of speech. S Child— Imitates what is seen, felt and heard 92 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 93 First East Indian International Cleft Surgery Workshop The mother and other speakers of the child’s language reinforce this constant cycle of practice until he builds a stored sound-motorpattern in his brain for each sound of his native language. It is these stored sound-motor patterns that will later be used in different syllable combinations to make up the words of the child’s language. L E This cycle, external reinforcement and storage is what permits us to habituate sounds and make them readily available to use when we begin speaking. Child— sees a “cat” and says cat C With or without a cleft palate this process occurs normally in all children and is essential to speech development Children with unrepaired cleft palates during this vital speech learning time will engage in this cycle as well. However, these children are handicapped by the inability to feel the sounds they see and hear or to reproduce them with intact organs of speech. This in turn leads to the habituated storage of incorrect sound motor patterns for each speech sound. T U Each sound has 4 characteristic features that make it different from each other sound. These features are created by using the organs of speech in different combinations. Each sound has its own sound-motor pattern just like a musical note. R The 4 features of each sound are: – Place (where in the oral or nasal cavity the sound is made) – Manner (what the organs of speech do to the air flow coming from the lungs) – Air Direction (whether the air exits from the nose or mouth) – Voicing (whether the vocal cords vibrate or not) Lacking an intact hard and/or soft palate, the child with a cleft will be unable to create some of these features or combine them in a conventional way. He will adopt incorrect ways of making each sound in his attempts to override the open palate. This results in cleft palate speech. Speech that contains incorrect sound-motor patterns and speech that is firmly habituated and resistant to change even after surgical correction of the origin of the problem has been done. 93 E S 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 94 Cirujanos Plástikos Mundi Effective speech therapy is needed to change this problem. RSF-EARTHSPEAK teams are working as volunteers in developing nations to teach parents and others about the nature of the cleft palate speech problem and how to correct it. Speech seminars and weeklong speech camps to train parents in the Corrective Babbling approach are held. This approach is meeting with success and can be an effective tool in helping overcome the speech deficits of children born with cleft palate.

Member of the Board of Directors for Interplast, Inc. THE GENETICS OF CLEFT LIP AND PALATE Clefts occur in approximately 1:700 births. 1:750 births in Caucasians 1:500 births in Asians 1:1200 in Africans E C T Clefts can occur as cleft lip alone, cleft lip/palate, or cleft palate alone Cleft lip alone: 21% of clefts Cleft lip/palate together: 46% of clefts Cleft palate alone: 33% of clefts Bilateral cleft lip is associated with a cleft palate in 86% of cases U Clefts occur in boys more commonly than in girls Ratio of cleft lip: left 6:right 3: bilateral 1 R Causes of clefting: For most, no single factor can be identified as the cause. Isolated clefts are those that have no other birth anomaly. Syndromic clefts are those associated with other birth disorders. Clefts are a feature of over 300 Syndromes, and most are rare. More common syndromes: Pierre-Robin sequence, Crouzon, Apert, Pfeiffer, Van der Woude, Treacher Collins, Velocardiofacial Syndromal clefts make up 15% of cleft lip +/- palate 50% of isolated cleft palate 75% of VPI are syndromic Isolated clefts: caused by an interaction between an individual’s genes and certain environmental factors (often impossible to identify). Phenytoin, Accutane, alcohol, tobacco, folic acid and pyridoxine deficiencies have been associated with clefting. 95 E S 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 96 Cirujanos Plástikos Mundi L E C T U Increasing parental age, especially an older father, is associated. About 35% of clefts have a positive family history. Human Genome Project: identifying genes related to clefting. Genes related to the production of tissue growth factor alpha, and fibroblast growth factor receptors have shown an association with clefts. Genetic testing may soon allow us to predict those families that may have a higher risk of cleft babies, although, as Dr. Millard says, “There is little chance that the molecular geneticist will arrive in an operating room with a cleft repair gene attached to a retrovirus anytime soon.” What are the risks that another family member will be born with a cleft? For parents of one cleft child: 2-5% risk of a second child with a cleft If additional family members have clefts: 10-12% risk For a person born with a cleft: 2-5% risk of having a cleft child If additional family members have clefts: 10-12% risk For siblings of a person with a cleft: 1% risk If additional family members have clefts: 5-6% risk If a syndrome is involved: risk can be as high as 50%. These patients should have a genetic evaluation. Cleft lip and/or palate implies a risk of recurrence that ranges from incomplete CL alone to bilateral CL and P. Cleft palate alone implies a risk for cleft palate only; these families are not at risk for cleft lip. Genetic Evaluation: R E S Obtain a detailed family history, a medical history, and physical examination of the cleft patient, and laboratory testing. 1. Verify that the cleft is “isolated” and not part of a syndrome. 2. Evaluate whether other relatives have similar conditions, andhow closely related they are. The greater the number of relatives known to have clefts, and the closer their biologic relation, the greater the risk of recurrence. 3. Consider the type and severity of the cleft. Clefts tend to be consistent within families, although severity can vary. 4. Testing: chromosomal testing is a syndrome is suspected; radiographs; molecular testing is available for some specific conditions; photographs. 5. Counseling: discussion of treatment necessary; risk of recurrence; discussion of strategies for future prenatal diagnosis. 96 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 97 First East Indian International Cleft Surgery Workshop L Donald R. Laub, M.D., FACS Adjunct Clinical Associate Professor of Surgery, Stanford Medical School Founder, Interplast Welcome E C You are attending a workshop on helping the cleft patient. This work is the most noble and most important and most effective work of mankind. You don’t require to be congratulated. Because you are— T Professional person A professional person; each one of you is a professional person, that is a person who has devoted his or her life to a skill and a science, and you practice that skill for the good of the other person. This act produces a very comfortable feeling —immediate gratification if you will— when you have helped someone with a severe deformity and significantly changed their fortunes for the rest of their lives. U R Psychic Income This is the Psychic Income. A professional person does the work for the good of the other person, which is in contrast to the non-professional person who performs his skill for the good of himself primarily. For example, the infamous CEOs of large corporations. This Psychic Income is so powerful that it possibly produces a chemical affecting the brain that addicts us to do this type of work. Psychic Income is the motor which runs all Plastic Surgery Voluntary Foundations, and it is the motor for CPM (Cirujanos Plastikos Mundi), and it is what makes the world go around as far as the Plastic Surgery organizations designed to help the developing world are concerned. For example, the founders of most plastic surgery helping foundations and most of the foundations devoted to orthodontia, speech therapy, ENT, dentistry, to help the cleft child, both the founders and the members, relate a similar personal experience 97 E S 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 98 Cirujanos Plástikos Mundi on the occasion of taking care of the first child they have had the privilege of helping with their skill. Many or most of these people relate that at the moment of receiving this special psychic income that it caused a change in their value system to be more humanitarian. In a way it was the child that helped the professional, to change their life to be more humanitarian. L E It is as if the “tail is now wagging the dog”, the tail being the Psychic Income and the Dog being the Physician and the paramedical person, who receives impetus to do this type of work or to form to a professional foundation. Here the patient becomes the one who produces the result in the surgeon. This phenomenon of the Doctor needing the patient reverses or erases our preoperative mind set that the surgeon is the almighty one and the patient is entirely a recipient of the surgeon’s skill and benevolence. We are all on a horizontal relationship: doctor + patient both, not a vertical relationship C T The team of a foundation must also consist of businessmen, accountants, lawyers and fundraisers; and all of these are vital to our life. In this instance, people with these skills are also professionals because they are working for the other person and they derive the same Psychic Income as the physicians do, because they are acting as surrogate surgeons or surrogate medical professionals. After all, it is because of these surrogate physician professionals that all of this is made possible. U When these two types of skills work together, we form a new way of practicing medicine. It is in these foundations where there is a true teamwork, where medicine and business truly work together for the patients benefit and for each other’s betterment of their individual specialty. R A true combination of business and medicine is produced by the commonality of humanitarianism. In this case, one + one equals three: it is obvious that medicine and business working together is a very powerful unit. E S All of the elements in this process evolved at many places simultaneously. My experience is for example at Stanford where, as at the other places, it was recognized that the needs of the students and the residents in training would be better solved in the setting of these programs. The acquisition of the psychomotor or surgical skills by trainees in these programs was excellent. This method of teaching is second to no other method. The residents who were there for the reason of learning the clinical or surgical parts of this process were delighted with what was going on; they were learning what is or was the very epitome of the field: the cleft lip repair and the cleft palate repair, and the nasal reconstruction for the cleft: for them this was the highest achievement toward their goal of learning surgery. 98 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 99 First East Indian International Cleft Surgery Workshop Peak Experience As they learned skills, they were sort of in a state of ecstasy because this constitutes a peak experience for the trainee. Value Change L A Peak Experience occurs at birth, when we are married, or are divorced, or graduate, or receive an award—or perform our first cleft lip repair. At the time of a peak experience, our value system can change. For example, at the conclusion of this landmark operation for them, they might say, “This was the best experience I have ever had in my life; I want to do this for the rest of my life.” At that moment in the training stage, the imprinting is apt to be much more permanent, meaningful, longlasting, and appropriate, than if these values of humanitarianism are transferred or acquired at a post-residency level. This process easily occurs for all practicing physicians and surgeons at any point in their careers; and it happened to me in early residency, and I assume it occurs for you at every cleft surgery. The imprinting is best done at the time in our careers set aside for learning “to the max”, which is residency or fellowship training. When the trainee states, “I want to do this for the rest of my life,” she or he has indicated that an attitude has been transferred to that “student” as well as a skill. Because the operation causing such psychic income was on a child where no fee was charged, this was a humanitarian act, so in this way the attitude of helping others was also transferred and imprinted. And I have heard, on 40 occasions, those words—at the end of the 1st cleft lip repair (repeat), “This was the best experience I have had in my life, I want to do this for the rest of my life,” a value change had occurred, and the skill and the social attitude became part of that person’s life from that time of the peak experience on. In Dr. Richard Jobe’s survey of the practicing surgeons who had undergone these experiences, as a resident, plus or minus 35% had continued practicing this work, and had retained this value. Interdisciplinary contact is necessary The patient changed the surgeon in a profound way; the “tail wagged the dog”; a good outcome resulted. Now turning to another aspect of our professional life, let me discuss the danger of a few in a University who achieve great excellence in a small field, and achieve power and notoriety within their system. The tendency to pout and cry may occur if each of your objectives is not immediately met by the Dean or the ruling class or your peers. The tendency is to say, “I quit, and I will form my own institute in order that I can practice excellence.” 99 E C T U R E S 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 100 Cirujanos Plástikos Mundi What happens in this case is that interdisciplinary contact is eliminated. The crossfertilization from different methods of thinking and from different related fields is eliminated. It’s probably more difficult to form multi-disciplinary efforts with equal emphasis given to all of the “ancillary” fields when your practice is with an institute without pluralism, even though the institute is seemingly the ideal setting. L The advancements in that particular field may then wither. The multidisciplinary approach has helped develop certain fields of surgery: E MULTIDISCIPLINARY INITIATIVES THAT HAVE WORKED: C T U R E S • Plastic Surgery • Cleft Surgery and Humanitarian Surgery • Cosmetic Surgery • Maxillofacial Surgery (both cosmetic and reconstructive). • Surgery for Craniofacial anomalies • Hand Surgery • Skin Physiology and aesthetic improvement based in this science • Microsurgery itself • Joint replacement Surgery • Neurosurgery for Epilepsy • Microsurgery including tissue tolerance and limb transplantation. • Bariatric Microsurgery • Ophthalmic surgery for retinal disease and for nearsighted patients. • Oncologic Surgery AREAS THAT HAVE NOT BENEFITED AS MUCH FROM THE MULTIDISCIPLINARY INITIATIVES: • Breast Surgery • Parts of Oncologic Surgery The theory behind Residents on Trips And in the future, the equilibrium between oral surgery and ENT and plastic surgery will require the skill and diplomacy that only occurs in a University environment and does not occur in an institute. 100 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 101 First East Indian International Cleft Surgery Workshop Hijo de tigre nacio pintado. The nourishment of our young, our own progeny in each of our “narrow” fields is important, and is on a par with the importance of the multidisciplinary effort. No doubt about it, the Teaching of the Residents in developed countries is as vital as teaching in other lands, because if the young (students and residents and impressionable youngsters) are not nurtured and induced to gain the excitement and pleasure of Psychic Income, the field will not reproduce itself. Withholding this process is similar to practicing birth control on your own professional discipline. Advances in development of our fields L E If the professionals do not teach in this way, they are sterilizing themselves. They prevent reproduction their own kind. Furthermore, medicine is not a static science, new operations and new advances are occurring at regular intervals. The inclusion of our residents in intense training experiences is a link in the chain, which advances our field. C T For example, in cleft lip and palate surgery, think of what should happen in the five years from now, and also think what will not happen in five years if you do not bring in new brains and new skills? For example: Intrauterine fetal surgery will not be developed to repair cleft lip. New operations will not have been developed, e.g., Mike Carsten’s (a resident) embryologic concept of moving the bone and the soft tissue as one neurovascular unit to repair cleft lip and craniofacial anomalies.1 U R E The Most Important Thing Enthusing young people to enter our field is clearly vital to ourselves and to the patients, who are the most important thing. Repeat, Humanitarianism should be taught at the age when teaching is done, is best done, is most effective. Carsten has shown that Clefting occurs when one neurovascular unit of bone and soft tissue unit become deficient during fetal development and that the repair of cleft should be based on this concept. 1 101 S 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 102 Cirujanos Plástikos Mundi “Enlightened self-interest” L E C In the greater perspective, we can consider the effect of our work on our world, which will occur only through our children, and our residents. Our children and our residents will be needed in the formation of public opinion in the next few years. Just think how the world would change if our governments and our corporations and our politicians were to regard this way of life as a thing of value. If our very own children felt that helping others in these ways were a thing of value they might counter-balance their conditioning toward their aspirations to acquire he latest clothing styles, the latest entertainment, and their latest idea about what they should acquire in life. But both aspirations seem necessary. Governments might divert a small billion or two toward these projects for their own good. Their own political projects would enjoy easier success. They would gain favor in the foreign countries and gain votes here in the developed world. Our corporations could actually make more money by being nice to people in foreign countries. This concept might mature into more than “enlightened selfinterest” (a phrase taken from history), but into a sincere value change. T U R A value change would increase the espirit of the employees in the large corporation; their company newspaper would tout the companies’ social conscience to the pride and delight of their more socially conscious employees, would raise the profits of the company and their “host” country; perhaps the actual expressed goals for the corporation would perhaps include the good of the employees; the shareholders and officers might see it this way, and all countries would benefit. This mindset is not really “thinking different” or O.O.T.B.2, but it is thinking in the longer term in an educated way, a bit more professional way. This thing of value should be regarded as equal to the tangible income of making money and parlaying that money into more money. The field moves forward. E Speaking of a modern, more educated method of “developing the field” of Plastic and Reconstructive Surgery: both in regard to the educational process and even the research, the innovative progression should include: Developed S & Developing 2 } Country Professionals working together.

This new concept leads to virtual centers of excellence because some professionals may be geographically separated but united by a web-based center of excellence (See Dingman PRS 2002). Again, to repeat, we are securing the development of new operations, of research, and of new surgeons. We see the development of multidisciplinary affiliated disciplines in both countries. Example of personal “Modern” History of theories discussed L E Consider some Stanford medical initiatives. Multidisciplinary humanitarianism, and Residents on trips C In 1963 at Stanford, Dr. Chase, my mentor and professional father, began our program with: a) Skill T b) The other person in mind. This combination led to the performing of a free surgery on a single patient, Antonio Victoria from Mexicali, Mexico and then later this led to the formation of Mexico Medical Project, Inc. and subsequently Interplast. Our first initiatives used for teaching, for obtaining patients with advanced pathology in our new hospital system, are examples of being committed to a goal. They were as follows: When challenged by the official opinion of the Mexican Government to not return to their fair country for further surgical work on children with developmental deformities, and adults with acquired deformity (burns, hand injuries, tumors), we pouted for only a short time. And then for some unknown reason conceived a “Plan B” for that situation. The government of Mexico had not initiated a more intense program to help their own citizens. At that relatively naïve time for us we “collaged” our assets (our group had 5 assets interlocking goals): Reconstructive Surgery Training, a knowledge of ships and the sea, a leadership experience with the U.S. Navy, an idealist in the law enforcement department of Los Altos, California, a veteran with personal experience in pre-juvenile delinquency rehab., a University faculty position, and a Rockefeller Foundation connection. We identified yard freighter 879 in the San Diego Reserve (Mothball) fleet and then, a Culinary Instructor, and also a retired Navy Captain for command, policemen to refer 14 year-old pre-juvenile delinquents for rehabilitation, a medical corpsman instructor, teaching faculties, textbooks (Lange Medical Synopses), David Werner’s paramedical volume, and a retired Naval electronics Veteran, and educators in 103 U R E S 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 104 Cirujanos Plástikos Mundi seamanship. The yard freighter has 35 feet of clear room with no internal cross member supports to allow an operating room, a post-op care unit, preparation room and a supply place. Quarters for the patients and crew were above deck. A lounge was to be identified. The kitchen was new, never used. The ship had been built in Philadelphia and towed to San Diego at the end of the war; it was kept air aconditioned for 25 years and maintained perfectly. L E C It drew only 3 ft of water and was ready for work in the shallow harbors of Western Mexico and South America. We visited the pentagon and arranged for the ship to be released at a certain moment, at which time we were to have our application on Capt. Banan’s desk. Any University has second priority to military material declared surplus. Dean John Wilson asked his nice friend at Rockefeller Foundation to arrange a grant for the project based on U.S. Navy experience and the experience gained. In Norway, where socially deviant persons learned self-worth, ability to not be selfcentered, and the necessity to work together as a team when working onboard a ship. Their programs resulted in less recidivision (back to jail or to the “Brig.”). Using the yard freighter in the San Diego Reserve Fleet, we had a method to train pre-juvenal delinquents in T a) Culinary arts b) Electronic skills U c) Seamanship d) Medical corpsman R E S Our second abortive attempt to do the type of work we are addressing in this symposium was the DC-3 airplane. The DC-3 was purchased by Interplast as safe and inexpensive transportation. It increased esprit du corps, higher and higher, until an unscheduled landing occurred, which of course led to another plan, to the formation of an Interplast “air force”, consisting of volunteer pilots and their airplanes, for transportation to nearby countries. It was another multidisciplinary initiative “assured” of success. These aircraft were used for transportation to clinics and hospitals in other countries, including parts of the U.S. The plan was inexpensive, running at 1/2 cost of commercial transport. Innovative funding from the community Initial funds were derived from: San Mateo Chope Hospital Surgical Medical funds Gender Surgery Fees Clair Elgin (a patient with the worst diagnosis and deformity who had “struck it rich” with her invention). 104 1270-8597-13528 Labio leporin** 18/9/03 09:14 Página 105 First East Indian International Cleft Surgery Workshop Our initial PRS patients were derived from: Physiatry Department (paraplegic and quadriplegic) Jail (Lombroso’s Theory that improving appearance improves social behavior) Menlo Park Veteran’s Administration Psychiatric Hospital (2,000 patients, many with skin cancer, Carpal Tunnel Syndrome, or Visual Field Defects, i.e. need for large scale blepharoplasty) And of course, Interplast—actually, Interplast was part of the educational process emanating from Stanford to provide pathology for residents and students. L E Success This initiative over the years lead to 2,000 patient surgeries from Mexicali, 4,000 patients and surgeries from San Pedro Sula, Honduras, 50,000 patients total from various countries and 40,000 patients from developing countries for Interplast Germany. C Dear colleagues—the personal example of commitment to Plastic Surgery and a multidisciplinary effort for those in need is related to you not for what sounds like self-interest, but I write it to you so that we might share the commonality of our humanitarian efforts, all of which are both personal and also in the name of all of us.
