The development of the cochlear implant has significantly altered the rehabilitation of those with severe or profound hearing loss. Whereas these individuals were previously offered sign language, lip reading techniques, and hearing aids, the cochlear implant now offers the possibility of improved sound detection and speech recognition. Its evolution mirrors the evolution of electronic technology. The initial benefit was one of sound detection. Now, through technological advances in speech processing as well as the design of the cochlear implant itself, open set word and sentence recognition occurs regularly. This review elaborates on the evolution of the cochlear implant, its cost-utility, determination of candidacy, and influences on postimplant auditory performance. It also explores areas of active investigation. The concepts of bilateral cochlear implantation and electro-acoustic stimulation devices are discussed.
