What device is surgically inserted within the inner ear to treat severe hearing loss?

A cochlear implant is a device surgically inserted into the inner ear to treat severe hearing loss. This device works by directly stimulating the auditory nerve, bypassing damaged hair cells in the cochlea. Unlike hearing aids, which amplify sound, cochlear implants convert sound into electrical signals that the brain can interpret as sound, providing a sense of hearing for individuals who may receive little to no benefit from traditional amplification methods.

The importance of this device lies in its ability to provide auditory experiences to those with profound hearing loss, making it a critical intervention for individuals who might not otherwise be able to benefit from other forms of hearing assistance. It provides access to sounds that can facilitate communication and speech development, significantly enhancing the quality of life for recipients. This makes cochlear implants an essential avenue for addressing severe hearing loss in individuals who are suitable candidates for the procedure.
