Management of congenital ear malformations.

In spite of modern diagnostic and surgical techniques, the results of congenital ear malformation surgery are often disappointing. Not only are hearing results less than expected, but also postoperative canal stenosis is a significant problem. This paper reviews the historical development of atresia surgery, the various classification systems, and the management of congenital ear malformations at The Otology Group. The authors' surgical technique is described and the postoperative results of 33 ear operations are discussed. Twenty-two of 33 cases showed some improvement in hearing. Postoperative stenosis occurred in 42% of atresia cases.
