摘　　要：目的:为乙状窦后径路小脑桥脑角内镜的应用提供相应的解剖学依据。方法:对20具(40侧)甲醛固定的成人头颅,模拟乙状窦后径路手术,观察颅内相关解剖并测量相关数据。结果:乙状窦后缘中点至听神经(近内耳门处)、三叉神经(近Meckel腔处)、舌咽神经(近颈静脉孔处)、内耳门后缘中点的连线长度和各连线与正中矢状面成角分别为(32.8±1.7)mm、(32.6±7.7)°,(46.3±1.8)mm、(31.4±4.1)°,(29.4±3.0)mm、(40.2±6.9)°,(31.2±2.0)mm、(32.7±4.9)°。结论:此数据为术中准确定位提供了参考。Objective：To privde anatomical basis for the surgical operation of endoscope-assisted retrosigmoid approach.Method：In 20 adult head cadavers fixed with formalin（40 sides）,the surgery via retrosigmoid approach was simulated.The anatomic features of the cerebellopontine angle were examined and measured.Result：The distance from the midpoint of posterior border of sigmoid sinus to acoustic nerve near internal acoustic pore,trigeminal nerve near Meckel′s cave,glossopharyngeal nerve near jugular foramen and the posterior margin of internal acoustic meatus were（32.8±1.7）mm,（46.3±1.8）mm,（29.4±3.0）mm,（31.2±2.0）mm.The tracks of degree of angle of median sagittal plane were（32.6±7.7）°,（31.4±4.1）°,（40.2±6.9）°,（32.7±4.9）°.Conclusion：The measurement provides some useful references for defining the position in operating.
