Abstract：
UNASSIGNED: The ZMC has a prominent shape compared to other parts in the midfacial region, thus small injuries will generate fractures in the ZMC. The management of ZMC fracture depends on the fracture deformity and the surgeon\'s considerations. Various studies have revealed the success of ZMC reconstruction with one fixation point to 4 fixation points fitting to the tetrapod shape.
UNASSIGNED: We report two cases of ZMC fractures which comparing the efficacy of 3- and 2-point internal fixations for improving clinical outcomes The first patient underwent ORIF which placed at 2 fixation points, the first point in the left ZF suture and the second point in the left ZMB. The second patient underwent ORIF reconstruction at 3 fixation points, the first point in the right inferior orbital rim, the second point in the right ZF suture, and the third point in the right ZMB.
UNASSIGNED: The most common surgical approach for ZMC fractures is through a gingivobuccal groin incision. This approach is for body exposure of the ZMB, which is the main buttress. The 3-point internal fixation improved the postoperative clinical outcome of fracture fragment stability compared to two-point fixation, but the mean malar height projection, vertical dystopia, and enophthalmos were not different between the two fixation methods.
UNASSIGNED: Three-point internal fixation can improve the clinical outcome of fracture fragment stability compared to 2-point fixation; however, it has a mean operative duration 22.2 minutes longer than 2-point fixation, so its application must be considered during the COVID-19 pandemic.

摘要：
■与中面部区域的其他部分相比，ZMC具有突出的形状，因此小的损伤会在ZMC中产生骨折。ZMC骨折的治疗取决于骨折畸形和外科医生的考虑。各种研究揭示了ZMC重建的成功，其中一个固定点到四个固定点适合四足动物形状。
我们报告了2例ZMC骨折，比较了3点和2点内固定对改善临床结果的疗效。左侧ZF缝合线中的第一点和左侧ZMB中的第二点。第二例患者在3个固定点接受了ORIF重建，右下眶缘的第一点，右边ZF缝线的第二点,和右边ZMB中的第三点。
■ZMC骨折最常见的手术方法是通过牙龈颊腹股沟切口。这种方法是用于ZMB的身体暴露，这是主要的支柱。与两点固定相比，三点内固定改善了骨折碎片稳定性的术后临床效果，但是平均马来人的高度投影，垂直反乌托邦，两种固定方法之间的眼球内陷没有差异。
■与两点固定相比，三点内固定可以改善骨折碎片稳定性的临床结果；但是，它的平均手术持续时间比2点固定长22.2分钟，因此，在COVID-19大流行期间必须考虑其应用。
