Background: The aim of this study is to evaluate the postoperative stability of zygomaticomaxillary complex (ZMC)fractures according to the number of fixation sites and to investigate the direction of postoperative displacement ofthe unfixed part of the fractured segment. Methods: This study was retrospectively performed on 38 patients who were treated by open reduction andinternal fixation of ZMC fractures and were taken postoperative computed tomography (CT) between February2012 and July 2019. The patients were classified into 3 groups: 1-point fixation, 2-point fixation, 3-point fixationaccording to the number of fixations. The postoperative displacement of the fractured segment was evaluated bythe superimposition between postoperative CT and follow-up CT, and the postoperative stability according to thefixation sites was investigated through the amount of postoperative displacement. In addition, it was investigatedin which direction the location of the fractured segment was changed in the unfixed fractured segment accordingto the fixation sites. Results: The amount of postoperative displacement of the fractured segment was 0.75 ± 1.18 mm on average. In the postoperative displacement of the distal area according to the number of fixation of the fracture, there wasno statistically significant difference in the amount of displacement of the fracture (p = 0.574). As for the direction of the change in the location of the fractured segment, 12 patients among 38 patients with thechange in the location of the fractured segment were investigated, and the displacement in the medial direction (n= 11, 91.67%) was the most common in all three fixation methods. Conclusion: In patients with a ZMC fracture who were treated by open reduction and internal fixation, the numberof fixations did not make the difference in the postoperative displacement of the fracture. In addition, the fracturedsegment mainly changes in the medial direction after surgery, and this fact can be used as a reference for thereduction direction during surgery for the stable prognosis.
