目的：参照小耳畸形患者健侧耳郭影像数据，制作三维耳郭导板，并打印为三维实体模型，为患侧耳郭再造提供手术指导。方法应用Mimics软件对患者健侧耳郭CT数据进行分割、镜像、膨胀等处理，获得患侧耳郭和导板的三维虚拟模型，将其导入3D打印机生产三维实体模型，并应用于临床。结果成功制作出个体化仿真度较高的患侧重建耳郭和导板的三维实体模型，并应用于临床耳郭再造术，用以指导术中精细雕刻耳郭软骨支架，并协助患侧再造耳定位。结论基于Mimics软件和3D打印技术制作的耳郭和导板的数字与实体三维模型，有助于指导术中精细雕刻耳郭软骨支架和定位。

Objective To provide guidance for auricular reconstruction by using three-dimensional auricle and guide plate based on auricular image data of the healthy side, and the three-dimensional solid model was printed. Methods The virtual three-dimensional model of the auricle and guide plate of the affected side was established by segmenting, mirroring and expanding CT data from the healthy auricle using Mimics software, which was further imported into a 3D printer to produce a three-dimensional solid model for clinical applications. Results An individualized and delicated three-dimensional solid model of a reconstructed auricle and guide plate of the affected side was successfully produced. It was used in auricular reconstruction for finer carving and localization of the affected auricle. Conclusion The digital and solid three-dimensional model of the auricle and guide plate obtained by Mimics software and 3D printing technology, may contribute a lot to the fabrication and localization of the affected auricle in microtia surgery.
