To privde anatomical basis for the surgical operation of endoscope-assisted retrosigmoid approach. 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. 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)°. The measurement provides some useful references for defining the position in operating.
为内窥镜辅助乙状窦后入路手术提供解剖学依据。在20具用福尔马林固定的成人头部尸体（40侧）上，模拟乙状窦后入路手术。检查并测量桥小脑角的解剖特征。乙状窦后缘中点至内耳道孔附近听神经、Meckel腔附近三叉神经、颈静脉孔附近舌咽神经及内耳道后缘的距离分别为(32.8±1.7)mm、(46.3±1.8)mm、(29.4±3.0)mm、(31.2±2.0)mm。正中矢状面角度度数轨迹分别为(32.6±7.7)°、(31.4±4.1)°、(40.2±6.9)°、(32.7±4.9)°。该测量为术中定位提供了一些有用的参考。 （注：原文中“privde”拼写错误，应为“provide”）
