借助硬质HoPkins杆状光导纤维内窥镜，对10例尸体作桥小脑角解剖学检查，分0、25和110度三种不同视角，卤素光源，窥镜直径4mm，经乳突进路沿小脑前缘插入，迷路后径路较乙状窦后径路为好，其优点是到达底池距离短，且对小脑压陷小。桥小脑角呈V形，底为脑桥臂，顶为小脑幕，在 With rigid HoPkins rod optical fiber endoscopy, 10 cases of corpus cavernosum anatomical examination for the angle of 0,25 and 110 degrees three different perspectives, halogen light source, endoscopic diameter 4mm, the mastoid process along the cerebellum The insertion of the leading edge, labyrinthine path than the sigmoid sinus posterior approach is better, its advantage is to reach the short distance of the pool, and the cerebellar depression small. Cerebellum angle was V-shaped bridge, the end of the pons, the top of the tentorium in
