Cochlea is a spiral shaped cavity, filled with fluid found in inner layer of the ear.1 It is vital in hearing process and auditory transduction, converting auditory received signals to neural impulses. People with hearing loss or impairment due to inner ear damage, even not able to hear properly with hearing aides, are fit cases for cochlear implant (CI). It is a device implemented to be used as sound processor, fitted behind the ear, receiving sound from outside. The sound signals are sent to the receiver, placed under the skin, to the electrodes in the cochlea. The received signals trigger cochlear nerve, sending the signals to the brain, hence sound is heard.
