The purpose of the present study was to explore the treatment and outcomes of bilateral craniomaxillofacial post-traumatic deformities with surgical planning, 3-dimensional (3D) model surgery, and preshaped implants.
We analyzed the preoperative computed tomography (CT) data and designed preliminary surgical plans for 3 patients with bilateral craniomaxillofacial post-traumatic deformities. 3D resin skull models were produced using rapid prototyping technology, and 3D model surgery was performed to determine the location, reduction direction, and shift distance of the osteotomy and to optimize the surgical plans. Titanium plates or mesh were preshaped on the models and then implanted into the patients. The complications, symmetry of the maxillofacial regions, mouth opening, and occlusion were observed 1 month postoperatively.
The patients had good recovery of their facial contour, occlusion, and mouth opening and acceptable symmetry of the bilateral maxillofacial regions. No complications were observed.
The combination of surgical planning, 3D model surgery, and preshaped implants can provide surgical accuracy and efficiency and good therapeutic outcomes in the treatment of bilateral craniomaxillofacial post-traumatic deformities.
本研究的目的是探讨采用手术规划、三维（3D）模型手术和预成型植入物治疗双侧颅颌面创伤后畸形的方法及效果。
我们分析了3例双侧颅颌面创伤后畸形患者的术前计算机断层扫描（CT）数据，并设计了初步手术方案。采用快速成型技术制作3D树脂颅骨模型，并进行3D模型手术，以确定截骨的位置、复位方向和移位距离，优化手术方案。在模型上对钛板或钛网进行预成型，然后植入患者体内。术后1个月观察并发症、颌面区域对称性、张口度和咬合情况。
患者面部轮廓、咬合和张口度恢复良好，双侧颌面区域对称性可接受。未观察到并发症。
手术规划、3D模型手术和预成型植入物相结合，可为双侧颅颌面创伤后畸形的治疗提供手术准确性和效率，并取得良好的治疗效果。
