Cochlear Implant

A cochlear implant is an electronic device; however, it is not a hearing aid. A small part of it is surgically implanted into the cochlea (inner ear) to provide direct electrical stimulation of the cochlear nerve. This stimulation is designed to allow individuals with severe to profound hearing loss to perceive sound. The cochlear implant system is comprised of three parts: the speech processor, internal devices, and speech coding strategies.

Cochlear Implant Process

Candidacy and successful use of a cochlear implant depends highly on a multidisciplinary team approach consisting of the patient and family, otolaryngology, audiology, speech language pathology, psychology, and social services.
