Platysma musculocutaneous flap: clinical and anatomic considerations in head and neck reconstruction.

The platysma musculocutaneous flap was used in 14 patients for reconstruction of the oral lining and external skin coverage in the head and neck area. Complications occurred in five patients. Only one patient, however, required further surgery and this was for correction of a poor cosmetic result. The skin and subjacent muscle are supplied by a major vascular pedicle from the facial artery and vein and a minor pedicle from the transverse cervical artery and vein. Either pedicle can be used as the pivot for the flap's arc of rotation. The donor defect can be closed primarily and did not present any problems. The flap can be raised with both its motor and sensory supply intact. The thinness and pliability, color match, and proximity make this flap a useful adjunct in head and neck surgery.
