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 the auricular auricular deformity with the middle and lower third of the aphrodysplasia and congenital trumpet-ear and shell-ear synthesis. Methods Ⅰ type auricle was repaired by folding and suturing cartilage; Ⅱ type auricle was repaired by local flap transfer; Ⅲ type auricle was repaired by soft tissue dilator combined with autologous costal cartilage scaffold. Results From October 2001 to March 2005, 4 cases of type Ⅰ butterfly pinna were repaired by folding and suturing of cartilage, which completely corrected the hyperextension of craniofacial cortex and reconstructed the ear boat and the ear wheel. The local flaps were used to repair Type Ⅱ butterfly auricle in 6 cases, after the operation, the auricle slightly smaller than the contralateral, the shape satisfactory; soft tissue dilator combined with autologous costal cartilage scaffold repair type Ⅲ butterfly auricle in 9 cases, postoperative graft cartilage, skin survived Good, auricle and contralateral size, shape consistent. Conclusions According to the severity of the deformity of the butterfly auricle, it is classified into Ⅰ, Ⅱ and Ⅲ types. The flap is folded and sutured by the cartilage flap, the local flap transfer method and the soft tissue dilator combined with the autologous costal cartilage scaffold, respectively. The operative effect is good , Suitable for promotion.
