Ear reconstruction using soft tissue expander in the treatment of congenital microtia

目的探讨先天性小耳畸形的手术修复方法。方法1992年至2005年采用皮肤软组织扩张器结合自体肋软骨支架移植的方法进行外耳再造共3 248例。结果经1至13年随访观察,再造耳廓皮瓣色泽红润、柔软、感觉功能无明显异常;移植耳廓软骨支架无软化、吸收、变形;再造耳廓位置、形态、大小和对侧基本一致。结论组织扩张器结合自体肋软骨支架移植的外耳再造方法,疗效满意、并发症少,是先天性小耳畸形理想的手术治疗方法。

Objective To explore surgical procedure of congenital microtia. Methods Ear reconstruction was made using soft tissue skin expander and autogenous rib cartilage framework. Results Long time follow-up showed that the flap of reconstructed ear was ruddy, soft, with normal sensory function ; cartilage framework had no degeneration, absorption and deformation. In addition, the reconstructed ears were coincidence with the normal side on location, form and dimension. Conclusions It was a good method for congenital microtia to use soft tissue skin expander together with autogenous rib cartilage framework at present time.
