The artistic surgical anatomy of the external ear is delicate and difficult to duplicate. The Cronin Silicone rubber (Silastic) otoplasty prosthesis for subcutaneous implantation allows a good cosmetic result in two stages. A not infrequent complication is exposure of the silicone rubber frame. The exposed silicone rubber should be trimmed and immediately covered with a local flap. Our series consists of nine ears with congenital microtia. Seven ears had a satisfactory result. The other two patients required removal of the implant secondary to self-induced trauma. The technique is recommended for selective clinical application.
