[Digital surgical technology in reconstruction of orbital frame].

Abstract

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.
