Meticulous anatomic dissection of the vasculature of the superficial anterolateral neck indicates that the platysma and overlying skin are supplied by direct cutaneous arteries measuring 0.5 mm in diameter. The small arteries are branches of the postauricular and occipital arteries in the upper lateral neck, the facial and submental arteries in the upper medial neck, the superior thyroid artery in the middle of the neck, the subclavian artery in the lower medial neck, and the transverse or superficial cervical arteries in the lateral aspect of the neck. These vessels traverse the undersurface of the platysma muscle to provide blood flow to the overlying skin. As opposed to this direct cutaneous system, the myocutaneous blood supply perforating through the sternocleidomastoid is scant. The platysma skin flap will survive if the blood supply from at least one region is preserved. In addition, it may be beneficial to include the external jugular and/or the communicating veins in the flap. By following these guidelines, the platysma flap has been successfully used for facial reconstruction in 7 of 8 consecutive patients.
