COCHLEAR IMPLANTS
Generally speaking, cochlear implants are for patients with severe-to-profound, sensorineural hearing loss.
There are approximately 500,000 patients in the USA with severe-to-profound hearing loss. Cochlear implants are
only recommended after the patient has tried
the most powerful and most appropriately fit hearing aids, and has
not shown sufficient benefit from hearing aids. Cochlear implants are devices that are "permanently" surgically
implanted into the inner ear.
Cochlear implantation is a surgical procedure performed by otolaryngology surgeons. Cochlear implants have been FDA
approved for almost two decades and the advances and improvements in the technology have been amazing. The Food and
Drug Association (FDA) and the American Medical Association (AMA) recognize cochlear implants as safe and effective
treatment for severe-to-profound sensorineural hearing loss. Most insurance programs pay (at least partly) for cochlear
implantation. Your audiologist, your otolaryngology surgeon and their appropriate office staff are experienced at managing
insurance issues.
Appropriately identified adults as well as profoundly deaf children (starting at age 12 months) can be
implanted. Research demonstrates that the earlier a deaf child is implanted, the better the long term result
will be with respect to speech and language development. Following surgery, rehabilitation is necessary, as
the child must learn to associate the sound signals with normal sounds. Regarding deaf adults, research suggests
that adults who receive cochlear implants are less lonely, have less social anxiety, are more independent, have
increased social and interpersonal skills, and of course, they hear better with the cochlear implant!
Cochlear implants are utilized in the patient who cannot benefit from hearing aids.
The cochlear implant is a device used to bypass the nonfunctional inner ear and converts
sound into electrical impulses that directly
stimulate the cochlear nerve. The implant
consists of an external portion comprised of
a microphone, sound processor, and external
coil and an internal portion that must be surgically implanted. The surgical procedure
involves the placement of an internal receiver beneath the skin behind the ear, and stimulating
electrode array, which is inserted into the cochlea or inner ear. The electrical signals are manipulated and
controlled by the audiologist to maximize speech perception.
The brain interprets these electrical impulses as
sound. Again, not all patients are surgical candidates, and not all cochlear implant recipients receive the same
benefit.
It is important to remember that the vast majority of the patients who receive cochlear implants
are actually "deaf" prior to implantation, and they have not been successful with traditional hearing aids.
Your audiologist is a very knowledgeable resource in regards to cochlear implants and will be happy to discuss
them with you.
