Title: Repair of moderate or severe full lip defect with composite lip flap pedicled with lip arteary
Abstract: Objective To explore a method for repairing moderate or severe full defect of lip. Methods One composite lip flap pedicled with lip artery was designed at one side of the defect. If the area of defect was too large, two flaps beside the defect should be designed, and one of two flaps could be extended to lower or upper lip at the angle of mouth to form the large composite lip flap which included the part of another lower or upper lip. The blood supply of this flap came from another side lower or upper lip artery, so it could not be necrotic. The flaps were cut along the design line and propelled to repair the defect. If one flap included the part of another lower or upper lip, the facial artery was ligated and cut at the branching point of upper and low lip artery, so as to increase the movement of the flap. First the oris orbicularis muscles were sutured, then the lip mucosa and skin were sutured separately. If the defect was located at vermilion, the flaps should be designed and cut along the vermilion boundary. Results This method was used in 67 cases, in which 38 cases were the upper lip defect and 29 cases were the lower lip defect. 20 cases were repaired by vermilion flaps and 47 cases by composite flaps which included vermilion and white lip. 10 cases were repaired by one flap and 57 cases by two flaps. The biggest width of the defect was 3.5 cm and the smallest was 1.2 cm. All the flaps survived. The repaired lip was plump and the postoperative appearance of the lip was satisfactory. Conclusions The lip artery is constant. The blood supply of the flap is reliable and anatomizing the flap is easy. The lip defect is repaired with the same tissue, so the lip's shape and functions can be recovered completely. This procedure can be widely used in repairing vermilion and white defect. It is an idea method for repairing moderate or severe full lip defect.
