摘　　要：目的评价实体眼眶模型及个性化三维预塑成型钛网在眶区骨折重建中应用的价值。方法经眼眶CT扫描数据创建虚拟眼眶模型，将数据输入快速成型机制备出实体眼眶模型，以此为模板预塑个性化三维形态钛网，对12例眶区骨折患者施行眶区整复手术。结果眶重建手术后，9例复视完全消失，3例极周边残存复视，眼球突出度基本一致，取得了较为满意的疗效。结论眼眶实体模型、三维预塑成型钛网技术能够提供更为完备及个性化的术前计划和治疗，有助于略去术中反复塑形以及试验性植入的冗余操作，有助于取得良好的眼眶重建疗效。Objective To evaluate the clinical application of solid physical orbital models and 3- Dimmension pre-bent titanium implants for orbital fractures. Methods 12 patients with orbital fractures were enrolled. First, virtual models were created based on the CT datasets. Next, the virtual model data were converted to the rapid prototyping machine to creat the solid physical models. Then the models were used as templates to cut and shape the titanium mesh plates in 3 dimensions. The 3-Dimmension pre-bent titanium mesh plates were implanted for surgical repair of the orbital fracture. Results Post-operatively, diplopia had been completely eliminated in 9 cases, except that extreme peripheral diplopia remained in 3 cases. Exophthalmometric measurements were approximately equal to each specific patient in the group. The outcome of orbital reconstruction using the pre-bent titanium meshes was favorable. Conclusion Solid physical orbital models and 3-Dimmension pre-bent titanium implants would lead to more predictive preoperative plan and more individualized reconstruction, would omit redundant trials for reshaping and refitting, would help to a- chieve more favorable surgical repair.
