Cochlear implantation in patients suffering from Cogan's syndrome

Among patients who receive cochlear implants, those with Cogan's syndrome make a unique group. On one hand they are part of the post-lingual patients and good results can be anticipated. On the other hand, their basic illness is thought to have an autoimmune aetiology and for that reason more susceptible to complications, especially flap problems. In a series of 60 patients who were implanted at the Sheba Medical Center, three had Cogan's syndrome. No post-operative complications, including flap problems, were observed (followed-up for at least 18 months). Subjective and objective hearing results were very good.
