Abstract
Acquired sensorineural hearing loss includes many conditions. The disparity between the number of children affected by the conditions which are supposed to cause hearing loss and the number of children actually deaf is not certain. Clinical features observed in children with surgically proven round window membrane rupture were noted. These features include otitis media, doubt about the hearing status in early life, disturbance of balance and other occasional neurological phenomena. Wide variation in the appearance of round window niche occurred in children with secretory otitis. Similar appearances were found in children with proven round window membrane rupture. They may represent a reaction to perilymph. Round window membrane rupture is probably common and may be a unifying factor for many cases of acquired sensorineural hearing loss. Occasional neurological phenomena are related to it.
