A cochlear implant is an implanted device that directly stimulates the hearing nerve in individuals with severe or profound hearing loss. It has become an important tool in clinical management of these disorders. As a group, veterans are likely to experience an increased rate of hearing loss. We evaluated the physical characteristics of cochlear implant electrode arrays and related these characteristics to the incidence of damage in the inner ear after implantation. This information will support the future development of improved electrode arrays and will inform people considering cochlear implant surgery.
