objective to introduce a method for repair of defects of alae nasi.methods transplantation of whole or partial free auricle composite tissue was designed in reconstruction of alae nasi.partial auricle composite tissue transplantation was used in 14 patients,the area of the graft was 1.0cm×1.5cm～1.9cm×2.5cm.whole auricle composite tissue transplantation was used in 6 patients,the area of the graft was 0.5cm×0.5cm～0.8cm×1.2cm.results all grafts survived.the grafts were dark red or light red in color,there were no blisters on them.follow-up of more than six months showed good results.conclusion in many methods for repair of defects of alae nasi,this method is simple,the appearance of alae nasi is good after operation and there is no new scar on face.

目的 修复鼻翼缺损。方法采用全层或部分耳廓复合组织游离移植的方法修复鼻翼缺损20例，其中以鼻翼残存瘢痕组织翻转作衬里，然后进行部分耳廓复合组织游离移植14例，移植物面积最小1.0cm×1.5cm，最大1.9cm×2.5cm；利用耳廓复合组织全层嵌入游离移植修复鼻翼缺损者6例，移植物面积最小0.5cm×0.5cm，最大0.8cm×1.2cm。结果 20例移植组织全部成活。色泽呈暗红至淡红不等，无水泡。随访半年移植物色泽与鼻组织基本近似，供区隐蔽。结论在诸多鼻翼缺损修复方法中，该方法简便易行、术后鼻翼外形好，面部显著部位不增加新的瘢痕，有独到优越性。
