Post-Auricular Skin Expansion for Microtia Reconstruction
-
摘要: 目的 探讨耳后皮肤扩张法施行耳再造的效果.方法 通过耳后皮肤埋置扩张器,注水扩张,第二期切取肋软骨制作耳支架,用扩张的皮瓣包裹,持续负压吸引耳廓成型,三期手术时进行耳垂转位,加深外耳道,完成耳廓再造.结果 用该方法完成小耳畸形耳廓再55例,随访6个月至2 a,除有5例出现扩张器外露、感染及耳软骨外露效果不佳外,除50例效果满意,再造的耳廓位置、大小、角度、外形与对侧耳廓基本对称.结论 耳后皮肤扩张的方法可有效解决耳造皮肤不足的问题.Abstract: Objective To evaluate the effect of retroauricular skin expansion forthe purpose of ear reconstruction. Methods In this technique called three-stage method: 1st soft tissue expander implantation under the skin close to the microtic ear, 2nd the autogenous rib cartilage is harvested, the ear framework is prepared and covered with expanded skin. 3rd the pseudomeatus, tragus and lobule are formed.Results 50 patients out of 55 patients were satisfied with their result and patients were followed up from 6months to 2 years and no complain were received, There were few case with minor complication of(Exposure of expander, Deflation or Infection, Exposure of framework, Steel wire extrusion, Hypertrophic scar, Chest wall deformities) and the complications were treated accurately and carefully and patients were discharged after recoveries.Conclusion The three-stage method is very useful in microtia by using costal autogenous rib cartilage.
