跨区供血的反流轴型耳廓复合组织瓣Ⅰ期修复大面积鼻翼缺损

One stage reconstruction for large alar defects with a straddling region reversal flow axial composite auricularisl flap

目的:探讨以眶上动脉或滑车上动脉为供血源的跨区反流轴型耳廓复合组织岛状瓣,修复大面积鼻翼缺损的临床应用特点。方法:从2004年5月～2008年3月间,我科选用游离眶上动脉或滑车上动脉与颞浅动脉额支的吻合支为供血源所营养耳廓复合组织瓣,经皮下隧道转移至鼻翼缺损区,Ⅰ期修复6例大面积的鼻翼缺损的患者。结果:在临床上将该方法应用于6例病人,除1例出现表皮水疱,后皮瓣部分坏死,面积约1.0cm×2.0,其余5例取得满意的临床效果。结论:反流轴型的耳廓复合组织瓣能Ⅰ期修复大面积鼻翼缺损,是一项极具推广的修复手段。

Objective To evaluate and explore the reconstruction technique of straddling region reversal flow axial composite auricular island flap with blood-supply from supraorbital artery or supratrochlear artery for repairing large alar defects. Methods From May of 2004 to Macth of 2008, 6 patients with the lager alar defects were studied. The patients were treated with reversal flow axial composite auricular island flap based on supraorbital artery or supratrochlear artery. Results 6 cases were treated with the technique, only one case underwent epidermal blisterand, and the partial skin flap necrosis, the necrosis area of flap was 1.0cm ×2.0cm, 5 cases were successfully repaired with satisfactory. Conclusion The island flap could be an ideal way for the one stage reconstruction of large alar defects, which is recommended to be widely used.
