To evaluate the application of digital surgical technology in reconstruction of orbital frame and assess the treatment outcomes.
Seven patients with post-traumatic orbital defect were included in this study. Images of the orbit were obtained for each individual through computed tomography (CT). Preoperative design was finished according to rapid prototyping, computer-aided design and computer-aided manufacturing (CAD-CAM) and other digital surgical techniques. Surgical fracture reductions with internal fixation and implant of Medpor were used in operation to reconstruct orbit as well as correct enophthalmos and diplopia.
Accurate realignment of the displaced orbital rim was obtained in all the 7 patients, and enophthalmos and diplopia were corrected in 4 and 2 patients, respectively.
Digital techniques provide a precise means for preoperative design and operation implementation during orbital reconstruction. As a result, complications can be reduced, and the patient's facial appearance can be maximally improved.
评估数字外科技术在眼眶框架重建中的应用并评估治疗效果。
本研究纳入7例创伤后眼眶缺损患者。通过计算机断层扫描（CT）为每位患者获取眼眶图像。根据快速成型、计算机辅助设计和计算机辅助制造（CAD-CAM）及其他数字外科技术完成术前设计。术中采用手术复位骨折并内固定，植入Medpor重建眼眶，同时矫正眼球内陷和复视。
7例患者均实现了移位眶缘的精确复位，分别有4例和2例患者的眼球内陷和复视得到矫正。
数字技术为眼眶重建的术前设计和手术实施提供了精确手段。因此，可以减少并发症，并最大程度改善患者面部外观。
