Nagata法全耳再造的临床应用研究

Clinical efficacy of Nagata's techniques in auricular reconstruction for microtia

目的：分析和探讨Nagata全耳再造法的临床应用价值。方法：对117例（120耳）先天性小耳畸形患者，采用Nagata全耳再造法，实施全耳再造手术。结果：经6个月～5年随访，平均随访1年，120只再造耳轮廓均得到满意再现；其中，早期5例患者在Ⅰ期耳再造术后位于对耳屏处的皮肤发生坏死，通过局部皮瓣的转移成功覆盖；1例患者在Ⅱ期手术后再造耳的背侧发生移植皮片的部分坏死和软骨外露，经局部皮瓣的转移后成功覆盖。结论：精致的软骨支架雕刻和保留皮下蒂的再造耳区皮瓣分离方法是Nagata法耳再造成功的关键。Nagata法全耳再造具有并发症少，再造耳解剖结构清晰和手术次数少等优点，是一种适合东方人种的全耳再造方法。
