Repair of upper lip defect with inferior labial artery island flap

目的探讨下唇动脉岛状皮瓣修复上唇缺损的可行性及效果。方法采用单侧下唇动脉岛状皮瓣修复上唇唇红及白唇局部缺损，皮瓣蒂部包括1条下唇动脉和2条下唇静脉。自2005年7月至2011年5月，共修复上唇缺损患者7例。结果本组7例患者，术后随访3-6个月，皮瓣全部成活，颜色、质地与周围皮肤相近，无明显的挛缩，皮瓣感觉功能良好，水从口中漏出明显改善，无口轮匝肌功能障碍，患者对上唇功能及外观都满意。其中，3例患者于术后3个月行唇弓、唇珠、人中成形术。结论应用单侧下唇动脉岛状皮瓣修复上唇唇红联合白唇局部缺损是一种比较理想的方法。

Objective To explore the feasibility and effect of inferior labial artery island flap for the repair of upper lip defect. Methods The inferior labial artery island flap which was designed on the lower lip with a vascular pedicle including one inferior labial artery and two veins, was used to repair the defects of the ipsilateral upper lip on totally 7 patients received from July 2005 to May 2011. Results After 3 to 6 months follow-up in all 7 cases, all flaps survived completely and had not visible contraction. The coloration and texture were closed to surrounding, and liquid leakage from the lip and the appearance of the injured area were clearly improved. Dysfunction of the orbicularis oris muscle was not observed, and sensory function was recovered within 6 months. The patient was satisfied not only with the function but also with the appearance of his lip. Conclusion The inferior labial artery island flap is an optimal method for the repair of ipsilateral upper lip defect.
