- Are There Implants For The Hearing Impaired?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: Though I read your column often I have never seen the following
- question answered. Is there an ear implant available for the hearing
- impaired? There have been eye implants available for a number of years for
- the sight impaired. If there are hearing implants how do I find them?
-
- ------------------------------------------------------------------------------
-
- ANSWER: Actually there are no eye implants available for the sight impaired,
- merely plastic lenses to replace the patient's natural lens removed because of
- cataracts. We are a long way from devising an actual eye to replace the one
- we were born with.
- As to ear implants, I consulted with Dr. Kenneth Brooks, of New York
- City, a specialist in otology and neurotology (the ears and their nerves).
- Here is a portion of his reply.
- "Yes, the cochlear implant is available for treatment of very severe
- hearing losses. Before receiving such a device, there must be a thorough
- hearing evaluation. This will include an attempt at using conventional
- powerful hearing aids, if they have not been tried before. Then medical,
- anatomical and surgical considerations are evaluated. The device is
- surgically implanted under the skin behind the ear, with a wire extending into
- the inner ear near the nerve of hearing. The sound received from a microphone
- at ear level is directed through a wire to a cigarette box sized processing
- unit usually placed in a pocket or a bra. The sound is processed into
- electrical impulses and directed through another wire to the implanted device.
- The processor and implanted device change sound into electrical impulses that
- stimulate the hearing nerve. The processor can be programmed to stimulate
- different parts of the hearing nerve. The nerve then carries these impulses
- in to the brain centers involved in understanding words. Depending upon the
- information, words may be clearly understood, or not well understood without
- looking at the source of the words and using lip reading. People with
- profound hearing losses that cannot be helped by the most powerful hearing
- aids currently use this device. If your hearing loss is mild, or can be
- helped with a hearing air, or you can still hear on the telephone, you are not
- a candidate for an implant.
- "There are cochlear implant centers throughout the country, to find the
- one in your area, you may inquire at your local ear doctor's office, or
- contact the hearing and speech center in any university hospitals near by."
