Clinical Application of the Dorsalis Pedis Free Flap for Reconstruction of Oral Cancer Defects

Abstract

The purposes of this study were to evaluate the clinical application and efficacy of the dorsalis pedis fasciocutaneous flap in the reconstruction of oral cavity defects and to assess the associated donor-site morbidity. From September 2009 to December 2012, 7 patients with associated oral cavity defects resulting from tumor resection underwent reconstruction with a dorsalis pedis fasciocutaneous flap. Surgical anatomy and harvesting procedure of the dorsalis pedis flap are described. Special consideration was given to the associated donor-site morbidity. All flaps survived without any complications. All 7 flaps were based on the dorsalis pedis artery and the greater saphenous vein for perfusion and drainage respectively. In all 7 cases, the donor site was closed with a full-thickness skin graft, with no associated healing complications or functional deficit of the foot. The resulting scar was well hidden in the lower extremity. The dorsalis pedis fasciocutaneous flap is a thin and pliable flap sharing many similarities with the radial forearm flap, thus making it ideal for intraoral reconstruction. Proper intraoperative and postoperative care of the donor site can result in minimal morbidity, as shown in this study. This flap may provide an ideal alternative to the radial forearm free flap, with the added advantages of a well-hidden scar and a high level of patient satisfaction.
