Abstract:
Objective:The purpose of this study was to evaluate the effect of computer-assisted surgical navigation in the reduction and fixation of unilateral zygomatic complex fractures.Methods:A retrospective analysis was performed on the patients suffering from unilateral zygomatic complex fractures treated by computer-aided surgical navigation technology in the Department of Oral and Maxillofacial Surgery, Hospital of Stomatology, Wuhan University from January 2013 to December 2017. Spiral CT was used before surgery, the data was imported into BrainLAB navigation workstation or AccuNavi—a navigation workstation to design the surgery plan, and then the surgery plan was imported into the surgical navigation workstation to assist the reduction and fixation of the zygomatic complex fracture. Three-dimensional CT was used within 1 week after surgery to measure the reference values of the postoperative healthy and affected zygomatic prominence, which were analyzed by the paired t-test. At the same time, the reduction of the fracture was evaluated by the difference of the bilateral reference values of the zygomatic prominence, and the absolute value of the difference less than 2 mm was judged as exact reduction. All patients underwent postoperative follow-up, and wound healing and facial appearance and functional recovery were evaluated. Results:A total of 45 patients were involved in this study, including 39 males and 6 females, aged 21-68 years old. The postoperative zygomatic prominence values of the healthy side and affected side were (80.78±6.14) mm and (80.85±6.10) mm, respectively. There was no statistical significance ( t=0.362, P=0.719) between the reference values of the bilateral zygomatic prominence after operation. The absolute value of the difference between the zygomatic prominence of the healthy and the affected sides after operation was (0.92±0.68) mm. Fourty-three cases achieved exact reduction of the fracture. In the other 2 cases, the absolute value of the zygomatic prominence difference was 2.3 mm and 2.2 mm, respectively. The surgical incisions of all patients healed well without complications such as infection, accompanying with satisfactory facial appearance and function recovery. Conclusions:The application of computer-aided surgical navigation in unilateral zygomatic complex fracture surgery can effectively ensure the accuracy of fracture reduction, and it is a valued application.
