Frequently Asked Questions About Cochlear Implants Surgery
What is a cochlear
Referred to as bionic ear, a cochlear implant is a device
that produces sense of sound electronically. The cochlear implants provide
hearing in patients who are hard of hearing due to damaged sensory hair cells
Cochlea is a part of the inner ear that comprises tiny
hair cells. When there is damage to the tiny hair cells in the cochlea, sound
cannot reach the auditory nerve. This type of hearing loss is known as
sensorineural. The cochlear implants bypass the damaged hair cells and directly
stimulate the auditory nerve. The implants allow sufficient hearing and unaided
understanding of speech.
Though the quality of sound with cochlear implants is
different and allows lesser information to be perceived and processed by the
brain, yet it helps in hearing and understanding speech and sound to a good extent.
What are cochlear implants comprised of and how
do they work?
The implant has two parts –
an external part that is placed behind the ear and an internal part that is
surgically placed under the skin.
Schematic of Cochlear Implant working
Components of external part and their function:
The external part comprises
of a microphone, a speech processor and a transmitter. The microphone picks up
sound and sends them to speech processor. The speech processor is small
box-like unit that analyzes the sound signals and send the sound signals to a
transmitter on the device worn behind the ear. After this the transmitter sends
the signals to the receiver implanted in the internal part under the skin.
Components of Internal Part and their function:
The Internal Part of the
device comprises of a receiver and an array of electrodes. The receiver takes
the coded signals from transmitter and sends them to the electrodes placed in
the cochlea. The electrodes directly connect with the auditory nerve and
stimulate the auditory nerve thereby produce sound sensations which are then perceived.
Profound sensorineural hearing loss in both ears

problems that would contra-indicate the surgery

be part of hearing world and communicate through listening and speaking
expectations for using cochlear implants
What is involved prior to getting a cochlear
Prior to getting a cochlear
implant, testing is done in the areas of audio logic testing, medical
examination and psychological examination. The tests such as X-ray, MRI as well
as counseling are done so as to help the candidate to benefit from a cochlear
implant and motivate him to participate in the process. Once the decision is
made, the surgery is done either on an out-patient basis or requires an
overnight stay in the hospital.
After a few weeks (about 4-6
weeks) the person is found to be fit with external parts with microphone and
speech processor and the implant is activated. Some additional visits for
activating and programming of electrodes may be required for the final
programming with speech processor.
