[Plastic surgery of aplasia of the external ear. Apropos of 65 cases].

Principles underlying reconstructive surgery of external ear for major aplasia are described and results presented for 65 patients treated using a cartilaginous framework of a costal autograft as described by B. Brent. Possibilities are discussed of combining this technic with auditory function surgery and the wearing of an auditory prosthesis within the framework of general care of major aplasias.
