Traditional three-point reduction may not restore proper projection of the malar prominence following a fracture dislocation of the zygoma if two of the three anterior points of realignment are comminuted. In such cases, reconstruction of the fourth or posterior projection, the zygomatic arch, increases the accuracy of the multidimensional reconstruction. Although the extended access approach required to repair the arch increases operative time and possibly length of hospitalization, its use is justified by the improved results in selected patients with severe injuries of the zygoma.
如果颧弓骨折脱位后三点复位法中的三个前复位点中有两个粉碎，则传统的三点复位可能无法恢复颧骨突出部的正确投影。在这种情况下，重建第四个或后投影，即颧弓，可提高多维重建的准确性。尽管修复颧弓所需的扩大入路会增加手术时间并可能延长住院时间，但对于某些颧骨严重损伤的患者，采用这种方法可获得更好的效果，因此是合理的。
