| Purpose: This study aimed to evaluate the role of using a prebent titanium mesh on a 3D-printed model as an intraoperative guide to reconstruct orbito-zygomatic-maxillary complex (OZMC) fractures. Subjects and method: TThis is a prospective, single-armed case series study carried out on twelve patients with unilateral displaced (OZMC) fracture indicated for orbital floor reconstruction as evidenced by clinical and radiographic examination. Open reduction and internal fixation were utilized to treat those fractures. Patients were collected from the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Tanta University. Post-operative evaluation: all patients underwent regular follow-up for six months. The following parameters were evaluated: visual acuity, the external appearance of the eye including hypoglobus and enophthalmos, diplopia, ocular motility, the aesthetic results, layout angle, gab length, and the zygomatic reconstruction. Results: motility of the affected eye in comparison with preoperative status as (P=0.001). The post-operative CT analysis showed that minimal layout angle and gap length values were highly correlated to obtain accurate reduction and fixation of OZMC. Significant improvements in the external appearance of the eye were obtained, including hypoglobus (P=0.001) and enophthalmos (P=0.003). Also, significant improvement in the limitation of ocular motility of the affected eye in comparison with preoperative status as (P=0.001). The post-operative CT analysis showed that minimal layout angle and gap length values were highly correlated to obtain accurate reduction and fixation of OZMC. Conclusion: The clinical and radiographical data suggested that more accurate reduction and fixation of OZMC fractures can be achieved using a prebent orbital titanium mesh on patient-specific 3D-printed RP orbital models. | ||||
