Abstract

After the surgical treatment of oral cancer, large orocutaneous defects developing in a contaminated or irradiated area are usually complicated and require operations for reconstruction. At our department, a pediculate regional flap has been often used to repair orocutaneous defects. However, from the viewpoint of preservation and restoration of oral cavity function and structure and the extent of the resulting defects, the repair of orocutaneous defects remains an unsolved problem.<BR>We describe a large orocutaneous defect associated with osteoradionecrosis that developed after excision of a tumor arising in the floor of the mouth. The large defect was reconstructed by combining a free omental graft with a delto-pectoral flap (D-P flap). The function and structure of the oral cavity was thereby preserved.<BR>Five years two months postoperatively, neither development of a new fistula nor osteoradionecrosis was observed. Our results suggest that a free omental graft is a useful method that should be considered for the repair of full-thickness defects in patients with oral cancer to ensure a better quality of life.
