A cochlear implant is a recommended treatment option for individuals experiencing complete deafness or partial hearing loss. This electronic device is placed on the cochlea and behind the ear to stimulate the nerve. This technology works by overriding the typical hearing mechanism, allowing for sound perception. Cochlear implants are commonly used to treat sensorineural hearing loss caused by damage to the small hair cells in the cochlea. These cells detect sound vibrations, which are then transmitted to the auditory nerve and sent to the brain for interpretation.
