ABSTRACT
The aim of this study was to apply an augmented reality (AR) navigation technique based on a head- mounted display in the treatment of craniofacial fibrous dysplasia and to explore the feasibility and the value of AR in craniofacial surgery. With preoperative planning and three-dimensional simulation, the normal anatomical contours of the deformed area were recreated by superimposing the unaffected side on to the affected side. We completed the recontouring procedures in real time with the aid of an AR navigation system. The surgical outcome was assessed by superimposing the postoperative computed tomographic images on to the preoperative virtual plan. The preparation and operation times were recorded. With intraoperative AR guidance, facial bone recontouring was performed uneventfully in all cases. The mean (SD) discrepancy between the actual surgical reduction and preoperative planning was 1.036 (0.081) mm (range 0.913 (0.496) to 1.165 (0.498) mm). The operation time ranged from 50 to 80 minutes, with an average of 66.4 minutes. The preoperative preparation time ranged from 26 to 36 minutes, with a mean of 29.6 minutes. AR navigation-assisted facial bone recontouring is a valuable treatment modality in managing craniomaxillofacial fibrous dysplasia and shows benefits in improving the efficiency and safety of this complicated procedure.
