A girl aged 15 was affected with a slight deformity of the right auricula and complete atresia of the external canal on the same side. She was treated by tympanoplasty and reconstruction of the missing external ear canal. The operation revealed the canal.atresia to be that of bony character ; a strong adhesion between the malformed maleus consisting almost of the head alone and the incus whose crus longum was considerably foreshortened. The mastoid cells were well developed. The audiog-ram showed a 55db loss before the operation ; after the operation this loss was 17.5db. There was 25db in the region of higher tones. In general there was 30db improvement of hearing after the operation as compared to that obtained before. The reconstructed ear canal remained patent.
