Abstract：
UNASSIGNED: Preservation of the facial nerve is of great importance in temporal bone surgeries. We intend to investigate the measurements of the radioanatomical factors related to the position of the facial nerve in accessing jugular foramen and internal carotid artery (ICA) in temporal bone of patients who were candidates for temporal high resolution computed tomography (HRCT) scan.
UNASSIGNED: In this correlation cross-sectional study, samples were selected from patients referred to Amir Alam Hospital who were previously candidates for temporal HRCT. Radioanatomic factors were evaluated in three axial, coronal and sagittal views. Analyzes were performed using descriptive statistics, correlation analysis and factor analysis.
UNASSIGNED: A total of 173 samples were investigated. The most reliable radioanatomical factor based on coefficient of variation (CV) was the distance of the 7th nerve to the temporomandibular joint (TMJ) in the inferior to the cochlea in the sagittal view (variable name S2) (CV = 8.1%) and then the distance from the 7th nerve to the TMJ in the inferior section of the cochlea in the axial view (variable name AI3) (CV = 8.4%). Based on correlation analysis and then confirmatory factor analysis, three common latent factors were identified (overall R2 = 0.999).
UNASSIGNED: The results of this study can be used for two purposes. First, the direct use of the estimated measures in surgical operations, and the second is more advanced modeling to choose the approach in the surgical operation and how to implement that approach. For the first aim, the two factors AI3 and S2 were the most reliable radioanatomical factors in different people. For the second aim, the three-dimensional understanding of the obtained measurements and the further identification of the anatomical nature of the latent factors can help in choosing the approach in surgery.

摘要：
■保留面神经在颞骨手术中非常重要。我们打算研究与在颞骨中进入颈静脉孔和颈内动脉（ICA）的位置相关的放射解剖学因素的测量，这些患者是颞骨高分辨率计算机断层扫描（HRCT）扫描的候选人。
■在这项相关性横断面研究中，样本从AmirAlam医院转诊的患者中选择,这些患者以前是颞叶HRCT的候选人.放射解剖因素在三个轴向进行了评估，冠状和矢状视图。使用描述性统计进行分析，相关分析和因子分析。
■研究了总共173个样品。基于变异系数（CV）的最可靠的放射解剖学因素是矢状视图中第7神经到耳蜗下颌关节（TMJ）的距离（变量名称S2）（CV=8.1％），然后是轴向视图中第7神经到耳蜗下段TMJ的距离（变量名称AI3）（CV=8.4％）。在相关性分析的基础上，再进行验证性因子分析，确定了三个常见的潜在因素(总体R2=0.999).
■这项研究的结果可用于两个目的。首先,在外科手术中直接使用估计的措施，第二个是更高级的建模，以选择外科手术中的方法以及如何实施该方法。对于第一个目标，AI3和S2两个因素是不同人群中最可靠的放射解剖因素。对于第二个目标，对获得的测量结果的三维理解以及对潜在因素的解剖学性质的进一步识别可以帮助选择手术中的方法。
