Fractures of the zygomatic-maxillary complex (ZMC) are common facial fractures. After adequate fracture reduction, it is important to maintain stability and rigid fixation to avoid functional impairment and aesthetic sequelae. In this sense, the fixation of just one point can provide sufficient stability of the ZMC fracture when the ZMC fracture is not crushed.
To analyze the success rates of fracture stability of the ZMC, incidences of complications, and aesthetic satisfaction after 1-point fixation.
This study followed the rules of PRISMA, with publications from 2010 to 2020. The chi-square test and the Poisson probability test were performed 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 -sq ( ) value was also analyzed among the complications variables.
The results of these studies showed in a general way that the use of 1-point fixation with open reduction presented good results in the short, medium, and long term, showing fracture stability. Complication rates were low and patients' satisfaction with aesthetics was considerable.
The success rate of the 1-point fixation procedure for the zygomatic-maxillary complex is high, with minimal complications.
颧上颌复合体（ZMC）骨折是常见的面部骨折。在进行充分的骨折复位后，维持稳定性和坚固固定以避免功能障碍和美学后遗症非常重要。从这个意义上说，当ZMC骨折未粉碎时，单点固定即可为ZMC骨折提供足够的稳定性。
分析ZMC骨折单点固定后的骨折稳定性成功率、并发症发生率和美学满意度。
本研究遵循PRISMA规则，纳入2010年至2020年的出版物。对并发症的发生情况进行卡方检验和泊松概率检验（低=1，中=2，无=0），采用α水平小于0.05，95%CI有统计学差异。还对并发症变量之间的-sq( )值进行了分析。
这些研究结果总体表明，切开复位单点固定在短期、中期和长期均取得了良好效果，显示出骨折稳定性。并发症发生率低，患者对美学效果的满意度较高。
颧上颌复合体单点固定手术成功率高，并发症极少。
