目的：探讨计算机导航技术在复合性眼眶骨折整复术中的应用。

方法： 对我院2014-01/2018-03收治的19例19眼复合性眼眶骨折患者施行计算机导航辅助骨折整复术。分析手术进程、术后患者骨折复位情况、眼球突出度、眼球运动、复视、眶下神经支配区感觉障碍、填充物位置及并发症等情况。

结果：所有患者手术过程顺利，术后随访6～18mo。术前所有患者均有眼球内陷，术后14眼完全矫正，5眼残存轻度内陷。术前10眼存在眼球运动障碍，术后7眼恢复正常，3眼好转。术前13眼存在不同程度复视，术后10眼完全矫正，2眼改善，1眼无明显变化。4眼术前存在眶下神经支配区感觉障碍，均于术后6mo内恢复。所有患者未出现严重并发症，骨折复位满意，填充物位置及深度理想。

结论：计算机导航技术应用于复合性眼眶骨折整复术，可提高手术精确性，手术安全有效。

METHODS: A retrospective review of 19 patients with complex orbital fractures were conducted. They underwent the reconstructive surgery assisted by image-data-based computer navigation. The pre- and postoperative data of enophthalmos, eyeball movement, diplopia, infraorbital numbness, and orbit CT image were recorded and analyzed.

RESULTS: The processes of pre-operation planning and intraoperative navigation were successful. During the 6 to 18mo postoperative follow-up, enophthalmos was completely corrected in 14 cases, while 5 patients had slight residual enophthalmos. Eyeball movement restriction was completely corrected in 7 cases, and was also improved in 3 cases. Diplopia was disappeared in 10 patients and improved in 2 patients, but still maintained in 1 patient postoperatively. Infraobital numbness was found in 4 cases, and dissappeared in 6mo postoperatively. No serious complications such as optic nerve lesion and vision loss were observed. Postoperative CT scans demonstrated that the fractures were corrected in all cases. The accuracies of the surgeries were satisfying.

CONCLUSION: Computer navigation system is a safe and effictive technique in assisting diorthosis in complex orbital fracture.
