Objective:
To evaluate the application of digital surgical technology in reconstruction of orbital frame and assess the treatment outcomes.
Methods:
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.
Results:
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.
Conclusions:
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.
