[Surgery of juvenile external ear abnormalities].

Surgery of moderate cup ear deformities, severe cup ear deformities and microtia is described. In cases of unilateral atresia auris we usually do not perform middle ear surgery. In cases of bilateral atresia the child is fitted with a bone conducting hearing aid as soon as possible and operated on when the child is 4 to 5 years old. After bilateral middle ear surgery we reconstruct the auricle at the age of 5 or 6 years.
