目的：探讨采用耳下区菱形皮瓣再造耳垂的临床应用及疗效评价。方法选取2013年9月至2015年7月耳垂缺损患者7例，根据耳垂缺损大小以设计耳下区全厚菱形皮瓣，以菱形皮瓣的短对角线为轴线，将皮瓣靠近缺损的一角与耳缺损下缘的顶点处缝合，沿轴线将皮瓣翻折，折叠法再造耳垂，术后随访再造耳垂形态及患者满意度。结果所有患者再造耳垂全部成活，切口均Ⅰ期愈合且均获随访，随访时间1～12个月，平均7个月。外耳轮廓自然流畅，耳垂形状、位置良好，与对侧外耳基本对称，术后再造耳垂未出现扭曲、变形，获得满意效果。结论采用耳下区菱形皮瓣修复耳垂缺损，操作简单，疗效可靠，可达到修饰性修复与重建的目的，符合现代整形外科的美学理念。“,”Objective To investigate the efficacy of rhombic subauricular flap in the repair of earlobe defects.Methods A total of 7 cases of earlobe defects were collected during Sept.2013 and July 2015.According to the size of the defect,full-thickness rhombic flap was designed.The flap was folded with the short diagonal as axis,and then the cor-ner of the flap near the defect was sutured with the apex of the lower defect edge.All patients were followed up,the shape of reengineered lobe was observed,and patients’satisfaction was recorded.Results All flaps survived,and incisions healed in the first stage.During the follow-up of 1 to 12 months (mean 7 months),the contour of the ear was smooth and natural,the shape and position of earlobe was fine,and no distortion or deformation occurred.All opera-tions produced satisfactory results.Conclusion Repairing earlobe defects with rhombic subauricular flap is simple and effective,which can achieve the purpose of decorative repair and reconstruction,and accord with the aesthetic concept of modern plastic surgery.
