Cochlear implants and multichannel auditory brainstem implants enable patients with bilateral total or profound hearing loss to receive at least acoustic information. Both types of prosthesis are based on electrical stimulation of the auditory pathway. Different speech coding strategies and the number of electrodes used may influence the postoperative results. The preoperative evaluation of patients is of utmost importance. The cochlear implant is suitable for patients with hearing loss due to inner ear disorders, but who have functioning hearing nerve. Patients with a defect of the hearing nerve can be provided with an auditory brainstem implant.

D000159	Vestibulocochlear Nerve	The 8th cranial nerve. The vestibulocochlear nerve has a cochlear part (COCHLEAR NERVE) which is concerned with hearing and a vestibular part (VESTIBULAR NERVE) which mediates the sense of balance and head position. The fibers of the cochlear nerve originate from neurons of the SPIRAL GANGLION and project to the cochlear nuclei (COCHLEAR NUCLEUS). The fibers of the vestibular nerve arise from neurons of Scarpa's ganglion and project to the VESTIBULAR NUCLEI.
