Abstract

The upper lip is a functionally and aesthetically important area of the face. Therefore, reconstruction of an upper lip defect needs sufficient consideration to ensure functional and aesthetic recovery. Several methods, such as wedge resection, rotation flaps, advancement flaps, and myomucosal advancement flaps, have been used to reconstruct vermilion defects. However, it is challenging to reconstruct a vermilion defect because of the possibility of residual asymmetry or scars and restrictions to normal lip movement after the reconstruction. We present the case of a 51-year-old female that had an upper lip vermilion defect caused by a dog bite. The lip defect was reconstructed using a mucosal V-Y advancement flap. This mucosal flap was based on the orbicularis oris muscle with a branch of the superior labial artery to ensure sufficient blood supply. Therefore, flap survival was excellent, and there was no constriction of the flaps. Moreover, the color and contour were matched to the adjacent lip tissue, and re-establishment of the white roll and adequate lip volume were achieved. This mucosal V-Y advancement flap technique represents a reliable method to repair mucosal defects without vascular compromise of the flap.
