Reconstruction of defects of the lip caused by cancer with its requirements of a complicated anatomical structure, important physiological function, and acceptable cosmetic result, is a challenge for oral and maxillofacial and plastic surgeons. A method that combines rotation and advancement flaps was described by Yu in 1989 for the reconstruction of defects of the lower lip. In our department between January 1992 and December 2012, 8 patients had reverse Yu flaps for the reconstruction of upper lip defects and 56 patients had classic Yu flaps for lower lip defects. Patients with defects located laterally to the upper lips, ranging from ⅓ to ½, had unilateral reverse Yu flaps, and bilateral procedures were done for defects of less than ⅔ of the lips. However, if the defects were located in the centre of the upper lips, between ⅓ and ½, they were treated with bilateral reverse Yu flaps. Patients with defects between ⅓ and ⅔ of lower lips had unilateral Yu flaps, and if the defects were wider than ⅔ of the lower lips, the procedure was bilateral. No flap failed and desirable functional and aesthetic outcomes were recorded in all cases. Here we report our experience with the Yu flap for the benefit of other surgeons.
唇部癌症所致缺损的修复，因其复杂的解剖结构、重要的生理功能以及可接受的美容效果等要求，对口腔颌面外科医生和整形外科医生而言是一项挑战。1989年，Yu描述了一种结合旋转皮瓣和推进皮瓣的方法用于下唇缺损的修复。在我们科室，1992年1月至2012年12月期间，8例患者采用反向Yu皮瓣修复上唇缺损，56例患者采用经典Yu皮瓣修复下唇缺损。上唇外侧缺损范围为1/3至1/2的患者采用单侧反向Yu皮瓣，唇部缺损小于2/3的患者行双侧手术。然而，如果缺损位于上唇中央，范围为1/3至1/2，则采用双侧反向Yu皮瓣治疗。下唇缺损在1/3至2/3之间的患者采用单侧Yu皮瓣，如果缺损宽度超过下唇的2/3，则行双侧手术。所有皮瓣均未失败，所有病例均获得了理想的功能和美学效果。在此，我们报告我们应用Yu皮瓣的经验，以造福其他外科医生。
