获得性耳廓缺损的修复

Surgical treatment of acquired ear defect

目的 探讨获得性耳廓缺损的手术修复方法。方法 采用组织扩张器结合自体肋软骨支架移植或Medpor支架置入、耳赝复体等多种方法进行修复。结果 长期随访观察，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；Medpor支架偶有外露；再造耳廓位置、形态、大小和对侧基本一致；耳赝复体外形佳，固定牢靠。结论 组织扩张器结合自体肋软骨支架移植的方法，疗效满意、并发症少，是获得性耳廓缺损的主要治疗方法；组织扩张器结合Medpor支架置人和耳赝复体制作治疗是其有益的补充。

Objective To explore surgical procedure for the treatment of acquired ear defect. Methods The ear reconstruction was carried out by using soft tissue skin expander and autogenous rib cartilage framework, Medpor framework, auricular prosthesis, and so on. Results The long-term follow-ups showed that the flap of reconstructed ear was ruddy, soft, with normal sensory function. The cartilage framework had no degeneration, absorption and deformation. The Medpor framework had no deformation. The contour of auricular prosthesis was vivid and the implant system was stable. In addition, the reconstructed ears were coincidence with the normal side on location, form and dimension. Conclusions It may be a major method for traumatic ear reconstruction that the soft tissue skin expander with autogenous rib cartilage framework could be applied at present time. In some special circumstances, the soft tissue skin expander with Medpor framework and auricular prosthesis may be other helpful choices.
