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.
上唇是面部一个在功能和美学上都很重要的区域。因此，上唇缺损的重建需要充分考虑，以确保功能和美学的恢复。几种方法，如楔形切除术、旋转皮瓣、推进皮瓣和肌黏膜推进皮瓣，已被用于重建唇红缺损。然而，由于重建后可能存在残余不对称或瘢痕以及对正常唇部运动的限制，重建唇红缺损具有挑战性。我们报告一例51岁女性因犬咬伤导致上唇唇红缺损的病例。使用黏膜V-Y推进皮瓣修复唇部缺损。该黏膜皮瓣以口轮匝肌为蒂，并带有上唇动脉的一个分支，以确保充足的血液供应。因此，皮瓣存活良好，且皮瓣无挛缩。此外，颜色和轮廓与相邻唇部组织相匹配，实现了白唇线的重建和唇部体积的适当恢复。这种黏膜V-Y推进皮瓣技术是一种修复黏膜缺损且不会导致皮瓣血管受损的可靠方法。
