应用颞浅动脉跨区供血的反流轴型耳后岛状皮瓣修复面部缺损

摘要

目的：探讨颞浅动脉跨区供血的反流轴型耳后岛状皮瓣在修复面部缺损中的应用。方法：根据颞浅动脉的解剖分布及其与耳后动脉的吻合特点，制备以颞浅动脉供血的耳后岛状皮瓣，经皮下隧道转移至受区，修复面部缺损。结果：本组19例患者，17例全部存活，皮瓣的形态、色泽及功能良好。2例早期出现静脉回流障碍,积极处理后,皮瓣远端仅有小部分表皮坏死。结论：颞浅动脉跨区供血的反流轴型耳后岛状皮瓣修复面部缺损，是比较理想的修复方式。%Objective To investigate the application of reversal flow axial retroauricular island flap based on the superficial temporal artery for facial defect. Methods According to the anatomical distribution of the superficial temporal artery and the anastomosis characteristics between posterior auricular artery and superficial temporal artery,we manufactured retroauricular island flap nourished by superficial temporal artery to repair facial defect via a subcutaneous tunnel. Results Among seventeen out of nineteen patients in this group,the transplanted skin flap survived and their shape、color and function were well.Two cases with venous reflux disorders in early stage was treated actively,only a small portion of the distal skin necrosised. Conclusion Reversal flow axial retroauricular island flap based on the superficial temporal artery is an ideal repairing way for facial defect.
