A novel technique of reconstruction of vermilion by pedicled myomucosal labial vestibular flap in traumatic defect of lower lip.

We present a new technique of reconstruction of a partial defect of vermilion in a case of post traumatic defect of lower lip. The vermilion defect was reconstructed by the myomucosal flap taken from the labial side of lip posterior and below the anterior lip defect. The lower rounded part of this 3 cm × 2 cm rectangular flap was brought on the outer anterior lip defect through a hole made by splitting the orbicularis oris muscle below the vermilion and its lower end was rotated upward to reconstruct the defect in the anterior and inferior part of vermilion. The secondary defect on the inner lip was closed by mobilization of mucosa. The triangular-shaped skin loss of anterior lower lip and its underlying muscle was closed in anatomic layers meticulously after mobilization of muscle and skin on both sides. The orocutaneous communication created was closed after 3 weeks by a minor operation under local anesthesia. The mouth opening remained normal between the period of lip repair and closure of iatrogenic orocutaneous communication. Good shape with normal color of vermilion and length having proper lip fullness was achieved without any microstomia. The surface of vermilion was smooth without any irregularity. The single scar of lower lip was supple and mobile over the underlying muscle. There was no deglutition, chewing, labial phonation, or any drooling saliva problems. The procedure provided functionally and esthetically satisfying result. We authors have not found a similar technique of lip reconstruction in the literature. Copyright:
