Detailed explanation-1: -It can be an option for people who have severe hearing loss from inner-ear damage who are not able to hear well with hearing aids. Unlike hearing aids, which amplify sound, a cochlear implant bypasses damaged portions of the ear to deliver sound signals to the hearing (auditory) nerve .

Detailed explanation-2: -Importance: Cochlear implants are a treatment option for individuals with severe, profound, or moderate sloping to profound bilateral sensorineural hearing loss (SNHL) who receive little or no benefit from hearing aids; however, cochlear implantation in adults is still not routine.

Detailed explanation-3: -In recent years, cochlear implants have been used in adults with sensorineural hearing loss. Cochlear implants replace the function of hair cells that are no longer able to generate electrical impulses in response to sound.

Detailed explanation-4: -Sensorineural Hearing Loss This type of hearing loss occurs when the inner ear or the actual hearing nerve itself becomes damaged. This loss generally occurs when some of the hair cells within the cochlea are damaged. Sensorineural loss is the most common type of hearing loss.
