Medial meatal fibrosis: the University of Western Ontario experience.

Medial meatal fibrosis is an uncommon but surgically treatable cause of conductive hearing loss. A review of 10 years experience with this entity at The University of Western Ontario revealed a total of 15 cases involving nine patients. Each of them was treated by one of four otologists. This disease may arise from either recurring or chronic infection or from chronic dermatitis, and it frequently presents with bilateral involvement. It may occur at virtually any age, and to our knowledge, this series includes the first cases of this disease to be described in children. The medical and surgical management of this condition is described in detail and the results are summarized.
