三维自体肋软骨耳廓支架的构建和应用

目的 探讨应用自体肋软骨构建三维耳廓支架的方法.方法 三维自体肋软骨支架由位于不同层面的耳轮、主体和基座组成,其构建过程包括肋软骨的采集、雕刻和组装.根据肋软骨的发育情况和拟制作耳廓的大小和高度,确定肋软骨采集的根数和雕刻的方法,并进行组装.结果 1992年1月至2006年12月,共收治先天性小耳畸形患者5 248例,形成耳廓6 252只,形态逼真、立体感强.经1～5年的随访,耳廓支架稳定,无变形和吸收.结论 本文所介绍的三维自体肋软骨耳廓支架制作简单,形态逼真、立体感强,最大限度保留了肋软骨的完整性.

Fabrication and application of three-dimensional autogenous cartilage framework in auricular reconstruction

Objective To explore the fabrication and application of three-dimensional autogenous cartilage framework in auricular reconstruction. Methods The process of fabrication of three-dimensional cartilage framework consisted of cartilage harvesting, carving and assembling the cartilage. The rib cartilage was harvested separately. The three-dimensional framework was composed of three main parts:the helix, the base and the pad, at different layer. The framework was fabricated according to the development of rib cartilage and contour and height of the reconstructed ear. Results From January 1992 to December 2006, 5 248 patients of microtia were treated with 6 252 autogenous cartilage frameworks. Conclusions The three-dimensional framework is easily manipulated. The reconstructed ears look natural and had an erect contour. This method can effectively use the cartilage.
