颧弓颞根骨折常作为颧上颌骨折的一部分发生。作者介绍了计算机辅助导航在矢状面骨折寰椎弓根拉力螺钉置入术中的应用，利用计算机辅助导航系统的术前规划，设计拉力螺钉的置入轨迹，计算螺钉的置入深度。在术前计划中，螺钉插入轨迹以10 °至15 °（平均：12.24 °）的前倾角放置，螺钉插入深度为9.0 mm至12.0 mm（平均：10.65 mm）。术中根据术前计划，在导航系统的引导下进行矢状骨折螺钉置入固定。术后CT扫描显示所有病例矢状骨折均精确复位和固定。计算机辅助导航是一个有用的工具，拉力螺钉插入在精确固定的矢状骨折颞根的颧上颌复杂骨折。
Sagittal fracture at the temporal root of the zygomatic arch often occurs as a part of zygomaticomaxillary fractures. The authors described the application of computer-assisted navigation in the lag screw insertion for the fixation of sagittal fracture at the temporal root of zygomatic arch. Using the presurgical planning of the computer-assisted navigation system, the trajectory of lag screw insertion was designed, and the insertion depth was calculated. In the presurgical planning, the trajectory of screw insertion was placed with an anterior inclination of 10 degrees to 15 degrees (mean: 12.24 degrees), and the screw insertion depth was 9.0 to 12.0 mm (mean: 10.65 mm). In the operation, the screw insertion in the fixation of the sagittal fracture was performed under the guidance of navigation system according to the presurgical planning. The postoperative CT scan showed exact reduction and fixation of the sagittal fracture in all cases. Computer-assisted navigation is a useful tool for the lag screw insertion in the precise fixation of sagittal fracture at the temporal root of the zygomatic arch in complex zygomaticomaxillary fractures.
