What is a cochlear implant?
Not all people with hearing loss have the potential to benefit
from hearing aid use; some may require the use of a cochlear
implant.
This is an electronic device implanted under the skin
behind the ear and in the organ of hearing (cochlea).
The implant consists of two parts, a behind-the-ear portion and internal
components.
The portion that sits behind the ear contains a microphone for
picking up sound, a processor to process the incoming sound, and a
transmitter to send the sound signal to the internal components.
The internal portion receives the sound information and sends it to the electrodes implanted in the
cochlea. Electric signals stimulate available hearing nerve fibers.
The signal is sent to the brain and sound is heard!
While the implant does provide sound stimulation, it is not a hearing aid and
does not work in the same way. Damaged cells in the cochlea are bypassed, and incoming sound is
coded into electrical impulses that stimulate the hearing nerve.
The choice to pursue this option is a serious one, since major surgery and costs are involved. Regaining
sound in a silent environment, however, is precious and
priceless.
