What are Cochlear Implants?
Cochlear implants (CI) are designed for individuals with severe to profound sensorineural hearing loss. These individuals receive little or no benefit from hearing aids. CIs bypass the non-functioning part of the cochlea in order to deliver electrical signals directly to the auditory nerve. They can be used effectively by both prelingually and postlingually deafened children and adults.
A cochlear implant consists of two parts, an external and an internal component.
The implant consists of a housing, which contains the electronics, and the electrode array as well as the receiving antenna and a magnet that holds the coil in place behind the ear.

The audio processor is worn behind the ear and consists of a control unit, a battery pack, and a coil that transmits information through the skin to the implant.
