Side selection for cochlear implantation in a case of Cogan's syndrome

초록

Cogan's syndrome is a rare clinical entity that is characterised by non-syphilitic interstitial keratitis and audiovestibular symptoms. The cause of Cogan's syndrome is considered to be autoimmune disease, which is supported by the resolution of hearing loss after steroid treatment, and the association with other autoimmune diseases. The sensorineural hearing loss of Cogan's syndrome is progressive over a few months, and sudden, bilateral deafness often occurs, which may be an indication for cochlear implantation. This paper presents the case of a young woman suffering from Cogan's syndrome and sudden, bilateral deafness. With reference to this case, we describe problems regarding cochlear implantation for Cogan's syndrome and radiological findings aiding selection of cochlear implantation side.
