META-ANALYSIS OF THE MAJOR CLINICAL FRACTURE RESULTS OF THE
ZYGOMATIC-MAXILLARY COMPLEX WITH 1-POINT FIXATION: SUCCESS RATE AND
Introduction: Fractures of the zygomatic-maxillary complex (ZMC) are common facial fractures. Annually 5.8 million people die from trauma worldwide. According to WHO data, head and face injuries can account for half of traumatic deaths. Objective: To analyze the success rates of fracture stability of the ZMC, incidences of complications and aesthetic satisfaction after 1-point fixation. Methods: This study followed the rules of PRISMA, with publications from 2010 to 2020. The Chi-Square Test and the Poisson's Probability Test were performed in relation to the occurrence of complications Low = 1, Moderate = 2 and NO = 0, adopting the α-level less than 0.05 with a statistical difference for 95% CI. The R-sq (R2) value was also analyzed among the complications variables. Results: The results of these studies showed in a general way that the use of 1-point fixation presented good results in the short, medium and long term, showing fracture stability, with or without open reduction. Complication rates were low and patients' satisfaction with aesthetics was considerable. Conclusion: The success rate of the 1-point fixation procedure for the zygomatic-maxillary complex is high, with minimal complications.
