Cochlear Implant

What is a Cochlear implant?

Cochlear implants are an electronic medical device that aids in the functioning of the damaged inner ear. Unlike hearing aids. The Cochlear Implants make sounds louder, and bypass the damaged hair cells of the inner ear (cochlea) to provide sound signals to the brain.

Who can be benefitted with Cochlear Implant?

  • Moderate to partial loss of Hearing.
  • Hearing aids does not give required results anymore.
  • Score 50% or less on sentence recognition tests done by hearing professionals in the ear to be implanted
  • Score 60% or less on sentence recognition tests done by hearing professionals in the non-implanted ear or in both ears with hearing aids.

How does a cochlear implant work?

For those patients, who suffers from damaged Hair Cells in the Cochlea or Inner ear region subsequently lost their hearing senses or hearing is compromised and cannot be further benefitted with hearing aid. The cochlear implant mechanically delivers / transfers the sound waves to the nerve for enabling the patient to hear clearly. The process is described below:

  1. A small device is fitted behind the ear or on the body. This device in turn converts the sound energy received from periphery into digital codes.
  2. These digital-codes are then transferred into the Implant device.
  3. The cochlear implant converts the digital code of the sound into electrical impulses and sends the same in the electrode array placed in the inner ear (cochlea).
  4. Thereafter, the Implant’s electrodes stimulate the cochlea’s hearing nerve, which then sends the impulses to the brain where they are processed into sound, and enable the person to perceive Hearing.

What are the benefits of a cochlear implant?

  • Hear better compared to hearing aid
  • Clinically significant results have achieved in people with a cochlear implant who can achieve an average of 80% sentence understanding, compared with 10% sentence understanding in patients with hearing aids1.
  • Focus well even in noisy environments.
  • Ease in understanding and hearing the person sitting across meeting tables, restaurants and other crowded places.
  • Feel normal in the world as they can hear alarms, people calling out and approaching vehicles.
  • Can use a phone with ease.
  • Enjoy entertainment programs having audio input.
