Cochlear Implantation in a Patient with Advanced Otosclerosis

Abstract

The incidence of otosclerosis, especially the retrofenestral advanced type, is relatively low in Koreans compared to that of the Western population. A case is reported in which cochlear implantation was performed in a patient with advanced otosclerosis presenting with mixed profound hearing loss on one side and pure sensorineural hearing loss on the other side. Intraoperative or postoperative complications of cochlear implantation commonly encountered in patients with otosclerosis did not occur in our patient and successful auditory outcome could be achieved. The results are reported with the review of literature, and clinical considerations regarding cochlear implantation in otosclerosis are discussed.
