Use of the free dorsalis pedis flap in head and neck repairs.
Many defects of the head and neck can be readily repaired with a free dorsalis pedis flap, and we report success with these flaps in 9 of 12 cases. A precise knowledge of the anatomy of the arterial supply of the flap is necessary. Preoperative arteriography is recommended  if the dorsalis pedis artery is not easily palpable, or if an anomalous distribution of the artery along the dorsum of the foot is sus pected. However, the transfer of the flap should be delayed for two weeks after preoperative arteriography is performed. The one-stage soft tissue reconstruction with a free dorsalis pedis flap has been associated with minimal morbidity and good acceptance by patients. A delay procedure for the flap seems to enhance the chances of complete survival which is so necessary in the repair of intraoral and pharyngeal defects. Careful attention to details and close monitoring of the flap will minimize morbidity. In case of an early failure of a flap, a secondary reconstruction by a different flap can be done in the first 48 to 72 hours. Early postoperative radiotherapy has been well tolerated over these free flaps.
