The bilobed myocutaneous pectoralis major flap in closure of combined intra- and extraoral defects.

Oral carcinomas may eventually invade the perioral soft tissues. In such cases, tumor resection creates through and through defects. Similar defects are seen in patients with gunshot wounds. The versatility of the bilobed myocutaneous pectoralis major flap in closure of these defects is emphasized. The results in nine patients treated by this method are discussed.
