摘要
目的:基于颞骨CT三维重建,研究垂直段及锥曲段面神经管的走行角度,为中耳乳突手术提供量化参考依据。方法:使用软件Able Software 3D-DOCTOR 3.5,对成人轴位CT影像进行三维重建,显示垂直段及锥曲段面神经管的走行。并用软件的自带功能测量及分析垂直段及锥曲段面神经管的走行角度,根据测得的数据研究其规律性。结果:依据三维模型面神经垂直段及锥曲段面神经管的走行角度,发现垂直段及锥曲段面神经管的走行中的不同节段偏斜角度具有一定的规律性。结论:颞骨CT三维重建可以准确地显示垂直段及锥曲段面神经管的走行特点,从临床实用的解剖学角度分析这些部位面神经走行特点及量化各段走行角度数据,有助于乳突手术中保护垂直段及锥曲段面神经免受损伤。
Objective：To study the vertical and pyramidal segment of facial nerve canal based on three-dimensional reconstruction of temporal bone CT,and provide a quantitative data for the middle ear and mastoid surgery.Method：Reconstruction of adult axial CT images shows the vertical and pyramidal segment of facial nerve canal.Using the Able Software 3D-DOCTOR 3.5 to show and measure the angle of the vertical and pyramidal segment of the facial nerve canal and to analyze the features and regularity based on the measured data.Result：According to the angle of the vertical and pyramidal segment of facial nerve canal based on the three-dimensional reconstruction model.A certain regularity has been found in the direction and the angle of different segments of the vertical and pyramidal segment of facial nerve canal.Conclusion：The temporal bone CT three-dimensional reconstruction can accurately show the characteristic and angle of the vertical and pyramidal segment of facial nerve canal.The characteristics and quantitative angle of the vertical and pyramidal segment of facial nerve canal from the anatomical viewpoint for clinical utility could keep the vertical and pyramidal segment of facial nerve from injury in temporal bone surgery.
