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.
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。
