Thin cutaneous flap for intra oral reconstruction: the dorsalis pedis free flap revisited.

Abstract

The dorsalis pedis flap provides thin, hairless tissue for a variety of intra oral defects. Due to concerns for the donor site, reconstructive surgeons have largely overlooked this flap, despite its numerous desirable qualities. The paper focuses on the anatomy of the first dorsal metatarsal artery and techniques which insure the preservation of adequate flap vascularity. The prevention of donor site complications centers around meticulous attention to the placement of skin grafts, with a secure tie-over dressing and the use of a posterior splint. Patients are allowed to ambulate in the early postoperative period only when venous compression is provided with an ace bandage. Vigorous attention to detail on reconstructing the foot has minimized donor site complications. The dorsalis pedis flap continues to be an important method of reconstruction in our armamentarium of free tissue donor sites.
