颞浅动脉跨区供血的反流轴型岛状耳廓复合组织瓣修复鼻翼缺损

Repairing nasal ala defect with a reversal flow axial island auricular composite tissue flap based on the superficial temporal artery

目的:探讨颞浅动脉跨区供血的反流轴型岛状耳廓复合组织瓣在修复鼻翼缺损中的应用。方法:根据反流轴型皮瓣原理,设计以颞浅动脉为供血的岛状耳廓复合组织瓣,经皮下隧道转移修复鼻翼缺损。结果:本组8例患者,7例全部成活,术后随访6～30个月,移植物的形态、色泽与正常鼻翼组织相似,效果良好。1例移植的岛状耳廓复合组织瓣表皮及部分软骨坏死。结论:颞浅动脉跨区供血的反流轴型岛状耳廓复合组织瓣修复鼻翼缺,是一种较为理想的修复方法。

Objective To investigate the application of reversal flow axial island auricular composite tissue flap based on the superficial temporal artery for alar ala defect.Methods According to principles of reversal flow axial flap,we designed auricular composite island flap nourished by superficial temporal artery to repair nasal ala defect via a subcutaneous tunnel.Results Among seven out of eight patients in this group the transplanted skin flap survived with 6 to 30 months＇ follow-up observation after operation,graft color and shape were very close to the ala nasal skin,with excellent results.One failed due to the transplanted auricular composite island flap skin and part of cartilage became necrotic after operation.Conclusion Reversal flow axial island auricular composite tissue flap based on the superficial temporal artery is an ideal repairing method for nasal ala defect.
