蝶形耳廓畸形的分型与手术修复

Calssification and repairment of “butterfly ear" deformity

目的对具有耳廓中、下1/3发育不良和先天性招风耳、贝壳耳综合特征的蝶形耳廓畸形进行分型及手术修复。方法Ⅰ型蝶形耳廓利用软骨翻转折叠缝合法修复;Ⅱ型蝶形耳廓采用局部皮瓣转移法修复;Ⅲ型蝶形耳廓运用软组织扩张器结合自体肋软骨支架法修复。结果2001年10月至2005年3月,应用软骨翻转折叠缝合法修复Ⅰ型蝶形耳廓4例,完全纠正了耳颅角过大,重建了耳舟和对耳轮;利用局部皮瓣法修复Ⅱ型蝶形耳廓6例,术后耳廓较对侧略小,形态满意;采用软组织扩张器结合自体肋软骨支架法修复Ⅲ型蝶形耳廓9例,术后移植软骨、皮片成活良好,耳廓和对侧大小、形态一致。结论根据蝶形耳廓畸形的严重程度将其分为Ⅰ、Ⅱ、Ⅲ型,并分别运用软骨翻转折叠缝合法、局部皮瓣转移法、软组织扩张器结合自体肋软骨支架法修复,手术效果好,适于推广。

Objective To classify and repair ＂Butterfly Ear＂ deformity which presents characters of dysplasia of inferior auricle of ear and congenital bat ear. Method The repairment procedures include： type Ⅰ： auricular cartilage flap inversion folding technique, type Ⅱ ： local ear skin flap . type Ⅲ ： soft tissue expander autogenous, fib cartilage framework. Results The method was used in 19 cases from October 2001 to March 2005. Postoperative follow-up showed satisfactory results in all cases. Conclusion According to ＂Butterfly Ear＂ deformity classification, different technique could be applied.
