ObjectivesTo introduce the surgical technique of 1-point fixation at the zygomaticomaxillary buttress (ZMB) and to verify its effectiveness using 3-dimensional computed tomography (3D CT).DesignCase series with chart review.SettingAcademic tertiary care medical center.Patients And MethodsThe study included 29 patients who underwent 1-point fixation at the ZMB for zygomaticomaxillary complex fractures without comminution of lateral orbital rim fractures. Preoperative and postoperative 3D CT scans were obtained to evaluate vertical and horizontal changes of the zygoma, which were were analyzed according to preoperative 3D CT findings.ResultsThe ZMB area was fixed with a resorbable system in 26 patients and with a metal system in 3 patients. After surgery, the mean vertical change improved from 1.28° to 0.58° (P < .001), and the mean horizontal change improved from 1.71° to 0.92° (P < .001). Postoperative vertical movement of the zygoma was not significantly affected by comminution of the inferior orbital wall, zygomaticofrontal process displacement, or comminution of the ZMB area and zygomatic arch (P > .05 for each). However, comminution of the ZMB area had an adverse effect on horizontal movement of the zygoma (P = .03). Complications after surgery included facial cellulitis associated with acute sinusitis in 1 patient, who was treated successfully. No patient required revision reduction because of facial deformity.ConclusionOur findings suggest that 1-point fixation at the ZMB provides sufficient stability of the zygomaticomaxillary complex without comminuted fractures of the lateral orbital rim.
