A cochlear implant is a surgically implanted device that provides a person with moderate to profound sensorineural hearing loss with the perception of sound by bypassing acoustic hearing altogether and directly electrically stimulating the auditory nerve. It has two main parts, an external sound processor worn behind the ear or, in some newer designs, held to the head magnetically, and an internal implant placed in the cochlea whose electrodes stimulate the cochlear nerve; with training and regular use, recipients learn to interpret the resulting electrical signals as meaningful speech and sound. The implant is placed under general anesthesia and typically allows same-day discharge, and outcomes afterward vary considerably depending on factors including the age of implantation, parental involvement and education level, and the duration and cause of the hearing loss.

FAQs
Does a cochlear implant restore normal hearing?
No. It gives a useful representation of sound and helps with understanding speech.
No. The National Institute on Deafness and Other Communication Disorders states that an implant does not restore normal hearing. Instead it gives a deaf person a useful representation of sounds in the environment and helps the person understand speech. The institute adds that learning to interpret the sounds the implant creates takes time and practice. This entry records what the source says and is not medical advice.
