Cochlear Implant

What is a Cochlear Implant?

A cochlear implant is an electronic medical device that replaces the function of the damaged inner ear. Unlike hearing aids that amplify sounds, cochlear implants do the work of damaged parts of the inner ear (cochlea) to provide sound signals to the brain.

Who is it useful for?

A cochlear implant may be helpful for people who:

Those who have moderate to severe hearing impairment in both ears, those who see little or no benefit from hearing aids, those who cannot improve their speech by using a hearing aid, those who score 50% or lower in the sentence perception tests performed by the hearing experts in the ear to be implanted, Scores of 60% or less on sentence perception tests performed by hearing care professionals in both ears using the device Many people use cochlear implants in both ears (bilateral). Listening with both ears can improve your ability to detect the direction of sound and separate the sounds you want to hear from those you don’t.

How do they work?

The Cochlear Implant is an electronic device designed to assist those with severe to profound hearing loss who may benefit little or no hearing aids. The Cochlear Implant system converts everyday sounds into coded electrical impulses. The stimuli stimulate the auditory nerve and the brain perceives them as sound.

A Cochlear Implant system consists of two parts:

The inner part that is placed with the operation-Implant, the outer part called the speech processor Who Can Benefit From Cochlear Implant?

Children and adults with congenital or acquired hearing loss can benefit effectively from the Cochlear Implant. While it is impossible to predict how much benefit will be gained from a Cochlear Implant, the following considerations are broadly valid.

Children with congenital hearing loss get the greatest benefit if they have Cochlear Implant surgery before the age of 5, especially before the age of 2. Those who have subsequently lost their hearing and those who still retain their speech and language memory may benefit more from the Cochlear Implant. The longer one has lived with severe hearing loss, the less benefit will be gained from the implant.
