Abstract This study was conducted on 20 patients with unilateral ZMC fracture to evaluate clinically, radiographically the validity of using two-point fixation technique in the management of zygomaticomaxillary complex fractures by using the zygomatic buttress as a key point of fixation and either the infraorbital rim or the frontozygomatic suture area as a second point of fixation. Radiographic assessment of the CT scans was done by measuring the malar width, malar projection, and malar height in the fracture side and in the normal side both preoperatively and postoperatively after 1 week and after 1 month. Asymmetry index comparing the normal side with the fracture side was measured both preoperatively and postoperatively to determine the accuracy and validity of the 2-Point Fixation technique in stabilizing the reduced ZMC fractures. Esthetical and functional clinical findings were recorded and evaluated both preoperatively and postoperatively after 1-week and 1-month to prove the reliability of this technique in management of ZMC fractures. Conclusion 1- ZMC is a key component to facial form and function, as it contributes to orbital volume, facial width, and malar prominence. Adequate diagnosis and treatment can readily restore facial and orbital harmony, but at the same time, inadequate treatment can leave the patient with severe deformities that are difficult to correct secondarily. 2- Stable fixation result and adequate esthetic outcome can be obtained by using 2-point fixation technique in non-comminuted ZMC fractures. 108 3- The zygomatic buttress as a key point of fixation through intra oral access have the best esthetic and functional outcome. 4- When the orbital floor needs reconstruction, Infraorbital rim used as the second point of fixation, otherwise the frontozygomatic suture area can be used as a second point of fixation. Recommendations 1- Adequate diagnosis and treatment planning using radiographic analysis and STL model surgery reduced time of surgery and points of fixation required. 2- Two-point fixation technique was reliable method in management of ZMC fractures and should be used when indicated. 3- Studies included a greater number of patients and longer follow up periods with quantitative analysis of postoperative symmetry are recommended. |
