全耳再造Ⅱ期立耳手术切口设计

Aesthetics choice of incision design in the second stage operation of pinna reconstruction

目的对2002～2005年北京同仁医院住院的全耳再造Ⅰ期术后病例,进行新切口设计方案的Ⅱ期立耳手术46耳进行讨论。方法全身麻醉后,沿耳轮外8mm处做皮肤切开,分离耳轮皮层,保留再造耳廓支架表面的软组织层,于耳轮背面切口处分离皮肤至耳轮外缘,并使分离后的皮肤向后延伸并缝于耳背部之软组织。结果手术病例均达到耳轮光滑,耳廓皮肤不肿,血运好,三角窝和舟状窝明显,耳廓后沟明显。结论此手术切口及缝合方法的改进更加符合患者对人工耳廓的美学要求。
