摘要： 目的探讨快速成形技术在全耳再造术中的临床应用。方法螺旋CT扫描获取患者健侧外耳影像数据,经Mimics软件转换成STL格式文件,建模后通过镜像技术应用于快速成形系统,构建患侧外耳三维模型,在二期法全耳再造中用于术中指导一期患侧小耳的自体肋软骨耳支架的雕刻及二期颅耳角的个性化重建。结果自2012年至今采用快速成形技术构建患侧小耳模型9例,重建外耳亚结构单位大于10个,颅耳角成形稳定。随访6~13个月,患者及家属满意。结论应用快速成形技术构建外耳三维模型,相对于传统二维胶片模型更为直观、立体,值得临床应用。

Abstract: Objective To explore the clinical application of rapid prototyping technology in ear reconstruction. Methods Image data of spiral CT scanning of normal side ear was converted into STL format files by the Mimics software. 3D model of affected ear was obtained by rapid prototyping system after modeling through image technique. Then the 3D model was guided for autologous rib cartilage bracket carving in stage one of ear reconstruction and individual reconstruction of cranio-auricular angle in stage two of ear reconstruction. Results Since 2012, 9 models of microtia were built by rapid prototyping technology. More than 10 substructure units of external ear were reconstructed. Cranio-auricular angle was stable. Patients were followed up for 6-13 months and were satisfied with the ear appearance. Conclusion Comparing with traditional two-dimensional film model, using rapid prototyping technology for the reconstruction of 3-D model of external ear is more intuitive and stereoscopic, and is worthy of clinical application.
