三种修复全耳廓缺失术式的临床应用分析

目的 探讨3种修复全耳廓缺失术式的最佳适应证,观察并比较其临床疗效.方法 对960例全耳廓缺失者分别采用皮肤软组织扩张术结合自体肋软骨支架法(786例)、皮肤软组织扩张术结合Medpot耳支架法(355例)、置桩赝复体法(24例)修复,分析不同术式的适应证,并对其临床效果分别进行评估.结果 3种术式均可获得满意的耳廓外形,肋软骨耳支架法适用于乳突区皮肤完好的30岁以下患者;Medpor耳支架法适合成年、特别是30岁以上,或局部皮肤有轻度炎性反应之患者;置桩赝复体法适用于耳后乳突区皮肤损伤严重,或不愿接受其他再造方式之患者.结论 根据适应证合理选择术式,方可获得满意的临床疗效.

Clinical application of three methods for total car reconstruction

Objective To investigate the indication and rosults of three methods for total ear reconstruction. Methods 960 cases of total ear defect were treated with skin expansion and autogenous rib cartilage framework(n=786), or skin expansion and Medpor framework(n=150), or ear prosthesis( n = 24). The indication and results of the three methods were analysed. Results Good cosmetic results were achieved with all three methods. Autogenous rib cartilage framework was suitable for patients under 30 years old with unaffected skin at mastoid region. Medpor framework was good for grown-up, especially over 30 years old, or with mild infection at mastoid region. Patients with severe skin injury at mastoid region or unwilling to accept surgery should choose ear prosthesis. Conclusions Satisfactory results can be achieved with suitable methods for total ear reconstruction.
