Y1 - 2020 N1 - T2 - Current Diagnosis & Treatment Otolaryngology—Head and Neck Surgery, 4e AB - A cochlear implant (CI) is an electronic device that restores partial hearing for patients with advanced hearing loss who gain limited benefit from a conventional hearing aid. Part of the device is surgically implanted under the skin and an electrode is placed within the cochlea to directly stimulate the auditory nerve, bypassing the damaged portions of the inner ear. Over the past 50 years, tremendous advancements have been made in cochlear implantation, from merely eliciting sound via direct stimulation of the auditory nerve to restoring functional hearing in hundreds of thousands of patients. Continued innovations in cochlear implantation technology, including shorter more flexible electrodes, smaller devices, incorporation of hearing aid technology, evolving speech-processing strategies, and refinements in surgical technique, including atraumatic, “soft surgery” principles and the development of alternative surgical approaches, have led to improved outcomes.
