[Atresia of the ear (author's transl)]

The results of operations for congenital deformities of the external and middle ear throughout a 10-year period, 1962-1972, are presented. 38 ears were operated upon, of which 26 obtained an average hearing gain of 25 dB. In 12 ears no improvement was obtained, and no ear became worse. Among the 15 patients with bilateral deformities 11 obtained a postoperative hearing in one or both ears of 40 dB or better, in average 30 dB.
