What is a cochlear implant?
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 in cochlea.
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.
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.

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.
Who is a candidate for cochlear implant surgery?
The candidate for cochlear implant surgery can be a child or adult with:
· Severe to Profound sensorineural hearing loss in both ears
· Having found limitations using hearing aid.
· No medical problems that would contra-indicate the surgery
· Loss of hearing after speech-language development.
· Strong desire to be part of hearing world and communicate through listening and speaking
· Have realistic expectations for using cochlear implants
What is involved prior to getting a cochlear implant?
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.
