Cochlear implantation in patients with autoimmune inner ear disease including cogan syndrome: A comparison with age‐ and sex‐matched controls

Abstract

To our knowledge this was the largest study of cochlear implantation in AIED and Cogan syndrome patients. In our experience, both groups generally attained high levels of post-CI speech perception and performed above average. Cochlear ossification affecting implantation in Cogan syndrome patients was not observed in our series, contrary to some reports.
