目的介绍一种中段耳廓再造矫正轻度小耳畸形的手术方法。方法对于耳廓大小为正常1/2或2/3的小耳畸形,采用保留耳轮脚和耳垂的中段耳廓再造法。以扩张皮瓣法耳廓再造为基础,根据残耳的形态个体化设计耳软骨支架形态,最大程度保留形态接近正常的残耳组织。结果自2010年至今,采用本法进行耳廓再造13例,术后无一例皮瓣坏死。再造耳形态良好,患者及家属满意,且多数无需三期手术。结论小耳畸形应根据不同程度选择适当的修复重建方法,对于保留了大部分正常耳廓形态但不能用复合组织移植方法修复的轻度小耳畸形,采用扩张皮瓣法中段耳廓再造较全耳再造可获得更好的治疗效果。

Objective To introduce a novel approach of mid-section auricular reconstruction for the treatment of mild microtia. Method Reconstruction of the mid-section of the auricle was used with preservation of existing crus helicis and ear-lobe in patients with mild microtia that were about 1/2 to 2/3 of normal auricular sizes. Local tissue was expanded and carti-lage framework was designed and constructed to fit the need of each individual patient, while preserving as much usable native auricle tissue as possible. Result Since 2010, 13 auricles were reconstructed with this approach. There was no postoperative flap necrosis. All reconstructed auricles were rated as yielding acceptable cosmetic effects. Most patients did not need addi-tional adjustment operations. Conclusion Auricular reconstruction should be guided by microtia classification which deter-mines the specific approach. For mildly microtic ears with near normal auricular appearance in which composite tissue trans-plantation reconst
