方法：选取2011-06/2015-10在我院住院并行眼眶整复的患者33例33眼，术前常规行眼眶三维CT检查，根据患者CT三维数字信息，通过CAD/CAM技术制作三维实体头模，术中利用三维实体头模将修复材料塑形，修复眼眶畸形。术后随访3～12mo，观察疗效。

结果：通过利用CAD/CAM技术修复眼眶畸形患者33例33眼的临床观察，除1眼术后过矫患者要求取出植入物，其余患者术后眼眶形态良好，眶区畸形及凹陷得到矫正，有效率97%，19眼术前伴复视及眼球运动障碍的患者16眼术后症状消失或改善，有效率84%，所有患者无手术并发症产生，手术效果满意。

结论：在眼眶畸形整复中，CAD/CAM技术能够缩短手术时间、提高手术效率、改善手术预后、降低手术风险。但是，实体头模的制作需要一定的费用，对于相对贫困的患者会产生一定的经济压力。

METHODS:Thirty-three patients(33 eyes)were included who were admitted and accepted orbital reconstructionin operation in our hospital from June 2011 and October 2015. The three-dimensional(3D)model was made by CAD/CAM technology, according to the orbital three-dimensional CT examination for each patient preoperatively, and the repairing materials were shaped under 3D entity model in operation. The patients were followed up for 3-12mo, and the orbital shape, enophthalmos, diplopia and eye movement were observed.

RESULTS:Among the 33 cases(33 eyes), except that 1 case required to remove the implants postoperative because of overcorrection, the patients were satisfied with the orbital shape. Enophthalmos were corrected. The effective rate was 97%. Among 19 cases(19 eyes)with diplopia and eye movement disorders, symptoms in 16 cases(16 eyes)were disappeared or improved, the efficiency rate was 84%. There were no operative complications.

CONCLUSION:The CAD/CAM technique is effective and practical in the reconstruction of orbital deformity with shorter operation time, higher efficacy, better outcomes and lower risk, and it is worth to be popularized in clinical application. But the fabrication of 3D model costs certain money which may bring economic pressures to poor patients.
