Cochlear Implants: when?
A cochlear implant is a surgically implanted
electronic device that can be considered for
people with severe to profound Sensorineural
hearing loss in both ears.
http://urmcmenshealth.com/2011/11/15/cochlear-implants-when-hearing-aids-are-not-enough
/
http://www.alphaonenow.org/hear_in_maine.htm
Who is the candidate in your clinic?
Hearing aids provide minimal benefit
Spouse functions as interpreter
Depends on written notes
Telephone use abandoned unless yes no
answers or cap tell.
Unable to understand TV unless captioned
Socially withdrawn
Depends heavily on lip reading
9
How does a Cochlear Implant
work?
The implant bypasses the
diseased or
nonfunctioning inner ear
hair cells by
converting the
sounds we hear to
electronic impulses
that directly stimulate the
inner ear nerve endings
Cochlea is Tonotopic:
High frequencies at base, low frequencies at apex
