A 23-year-old man presented with an 8-year history of unilateral hemifacial microsomia. A three-dimensional model of the maxillofacial bones was generated after acquisition of helical computed tomographic data. A customised implant model was designed by projecting a mirror image of the healthy mandible on to the three-dimensional model. A resin model of the implant was then made using a rapid prototyping machine. A polymeric biomaterial was sculpted according to the model and implanted into the affected side of the mandible to restore his facial symmetry. The hemifacial microsomia was corrected and a symmetrical facial contour obtained. No complications developed during the 6-year follow-up.
一名23岁男性，有8年单侧半侧颜面短小畸形病史。获取螺旋计算机断层扫描数据后生成了颌面骨的三维模型。通过将健康下颌骨的镜像投影到三维模型上设计了定制的植入物模型。然后使用快速成型机制作了植入物的树脂模型。根据该模型雕刻了一种聚合生物材料，并将其植入下颌骨的患侧以恢复面部对称性。半侧颜面短小畸形得到矫正，获得了对称的面部轮廓。在6年的随访期间未出现并发症。
