Submental Skin Flap for Intraoral Lining
Women with an excess of skin in the submental area yield the best results. The quality and flexibility of the skin are quite close to those of the mucosa. Male bearded skin is less desirable. Reconstructions following the primary resection of small T1-T2 cheek cancers, where the cheek skin is in good condition, are most satisfactory. Radiation therapy to the submental skin is a contraindication to the use of this flap.
The flap includes the underlying muscular fascia. Blood supply is from the anterior and inferior branches of the facial artery, and venous drainage is provided by the anterior jugular vein, which must be preserved. The dissection is started at the distal end of the flap to preserve venous drainage.
