Cochlear Implant Surgery

A cochlear implant is an electronic device that is implanted surgically to people who have sensorineural hearing loss. It aims to provide a modified sense of sound. Unlike hearing aids that are used as an amplifier of the sound whereas CI bypasses the normal acoustic hearing process to substitute it with electric signals resulting from the stimulation of the auditory nerve. Now, the brain interprets those signals as sounds.

There are two main components of this implant. The external component is a sound processor containing the microphones, a signal processor responsible for transmitting the signals, and is worn behind the ears.

The internal component has a coil to receive the signals, devices, and a series of electrodes to stimulate the cochlear never after implantation.
