目的 评价3D打印眼眶模型辅助预成型钛网修复眶壁骨折的精准性和安全性。 方法 眼眶骨折患者36例，分成两组：A组18例为试验组，采用3D打印眼眶模型辅助预成型钛网修复眶壁骨折。B组18例为对照组采用传统三维预成型钛网修复眶壁骨折，术后观察两组眶CT、眼球内陷、复视改善情况，评价3D打印眼眶模型辅助预成型钛网修复眶壁骨折的治疗效果。 结果 试验组在术后眼眶CT上可见钛网的边缘与骨折边缘精确吻合。眼球内陷矫正率：A组术后2周与3个月、6个月比较，有统计学差异（P <0.05），术后3个月与6个月比较，无统计学差异（ P >0.05）；B组术后各期均无统计学差异（ P >0.05）；复视矫正情况：A组、B组术后2周与3个月、6个月比较，3个月与术后6个月比较，均无统计学差异（ P >0.05）。 结论 应用3D打印眼眶模型辅助预成型钛网可以更加精准安全的修复眶壁骨折，提高眼球内陷和复视的治愈率。 Objective To evaluate the accuracy and safety of 3D printed orbital model assisted preforming titanium mesh in repairing orbital wall fracture. Methods Thirty-six patients with orbital fracture were divided into two groups:18 patients in group A were in the experimental group. 3D printed orbital model was used to assist the pre-formed titanium mesh to repair orbital wall fracture. Eighteen patients in group B were used as the control group to repair orbital wall fracture with traditional 3D preformed titanium mesh. Postoperative observation was made of the improvement of orbital CT, enophthalmia and diplopia in the two groups, and the therapeutic effect of 3D printed orbital model assisted with preformed titanium mesh in repairing orbital wall fracture was evaluated. Results In the experimental group, the edge of titanium mesh was exactly consistent with the fracture edge on postoperative orbital CT. Correction rate of enophthalmia:there were statistically significant differences between group A 2 weeks after surgery and 3 and 6 months after surgery(P <0.05), and there were no statistically significant differences between group A 3 months after surgery and 6 months after surgery( P >0.05). There was no statistically significant difference in each postoperative stage in group B( P >0.05). Corrections of diplopia:There was no significant difference between group A and group B 2 weeks after operation, 3 months and 6 months after operation(P > 0.05). Conclusions Using 3D printed orbital model to assist preformed titanium mesh can repair the orbit more accurately and safely, and improve the cure rate of enophthalmos and diplopia.
