- Moderate to partial loss of Hearing.
- Hearing aids does not give required results anymore.

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:
- 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.
- These digital-codes are then transferred into the Implant device.
- 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).
- 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.
