目的探讨微型钛板塑形内固定整复术，在三维CT重建技术的指导下，治疗眼眶骨折的临床效果。方法术前行横断面、冠状面二维CT扫描和三维CT重建，根据三维CT重建图像，采用微型钛板塑形内固定，对17例眼眶骨折患者进行骨折复位及眼眶骨缺损整复手术。结果17例术后复视及眼球运动障碍均消失，眼球内陷纠正，视力无损害，且面部外观满意，无植入体轮廓阴影或阶梯状畸形。CT扫描复查眼眶骨折及缺损处修复良好，软组织完全回纳，钛板无移位。术后随访3个月~1年，钛板无排斥反应、移位、感染及其他不良反应。结论微型钛板塑形内固定整复术，充分利用钛板具有的良好生物相容性、坚固强度大、可塑形但又不易变形、体内植入可永久留置等特点，达到眶缘结构良好的固定作用。同时在三维CT重建技术的指导下，眶骨骨折诊断更准确，手术更精确，盲目操作风险性更小，手术时间缩短，大大提高了手术安全性。

Objective To explore clinical effects of moulding internal fixation plasty with titanium mini-plate on orbital fracture under the guidance of 3D reconstruction technology. Methods Before the operation,cross-sectional,coronal 2D CT scan and 3D CT reconstruction were performed. Based on the 3D CT reconstruction image,moulding internal fixation plasty with titanium mini-plate mold was applied to 17 patients for repair of their orbital fracture and tissue defect. Results After the operation,diplopia and eyeball movement disorder of the 17 patients disappeared,enophthalmos was corrected,visual acuity was not damaged,and facial appearance was satisfactory;there was no implant outline shadows or ladder-shaped deformity. CT scan reexamination showed that the orbital fracture and soft tissue defect were repaired well,soft tissue was completely recovered,and the position of titanium plate did not change. The patients were followed up for three months to one year,during which,no rejection,infection and other adverse reactions caused by titanium plate were found. Conclusion Moulding internal fixation plasty with titanium mini-plate makes full use of the good biocompatibility and high strength of titanium plate,which can be molded but not easily deformed,and can be kept in human body permanently,achieving good fixation of the orbital margin structure. At the same time,under the guidance of 3D CT reconstruction technology,orbital fracture can be diagnosed more accurately and operation can be carried out more precisely,and blind operation risk becomes smaller and operation time can be shorten,which greatly improves the operation safety.
