Abstract

The aim: Radiographic evaluation of intraoral maxillary vestibular approach to the zygomaticomaxillary buttress and anterior arch fracture reduction technique with fixation versus without fixation for anterior arm of the arch. Patients and methods: Twelve male patients with unilateral zygomaticomaxillary fracture involving the zygomatic arch, reduction, and fixation applied by an intraoral maxillary vestibular approach. Group A comprised 6 patients with fractured zygomatic complex reduced and fixation with reduction of the zygomatic arch without fixation, Group B comprised 6 patients whose fractured zygomatic complex reduced and fixation with reduction of the zygomatic arch and fixation of anterior arm of the arch. CT scans performed, preoperatively and immediately postoperative, to assess the accuracy of reduction to the zygomatic buttress and anterior part of the arch. Results: The preoperative anteroposterior dimensions on the axial cuts of the CT scans for both groups showed the mean values of points A and B on the intact side to that of the fractured side no statistically significant difference. Comparing the mean values of point C on the intact side to that of the fractured one stated statistically significant difference between them. The immediate postoperative axial cuts comparing the mean values of the points A, B, and C on the intact side and the reduced side, there was no statistically significant difference between them for groups A and B. Conclusions: Reduction without fixation in uncomplicated cases where minimal intervention is sufficient, whereas fixation is crucial for achieving stability and reliable outcomes in more complicated scenarios.
