摘　　要：目的:为天幕区手术入路提供可靠的解剖学数据和资料。方法:将成人尸头开颅去脑,分别测量天幕裂孔区相关的颅神经及血管等结构之间的距离。结果:天幕窦通常引流入直窦、窦汇、横窦和岩上窦;动眼神经在前床突的后方(7±4)mm;滑车神经进入小脑幕距小脑幕游离缘为(1.6±0.6)mm;三叉神经感觉根在颅后窝开口的前缘距后床突(15.92±0.62)mm;Labbe静脉从离开颞叶到进入横窦的距离:左侧(2.8±1.3)cm,右侧为(2.4±1.2)cm。结论:在天幕内侧区和中间区的前方很少有静脉窦的存在,此区可以作为天幕切开的部位。天幕区手术时宜注意保护动眼神经、滑车神经、三叉神经感觉根和Labbe静脉。Objective： To provide anatomic data and information for the operations of tentorium cerebelli hiatus region. Methods： Twenty adult cadaver heads were cut along the line of the superciliaries, brain tissues were removed, and the nerves and blood vessels were measured. Results： Tentorial venous sinuses were drained into the straight sinus, the confluence sinus, the transverse sinus and the superior petrosal sinus. The oculomotor never was （7±4） mm behind the anterior clinoid process the distance of the trochlear never through the tentorial notch was （1.6±0. 6） mm to the free edge of tentorium, the distance of the trlgemlnal sensory root through the posterior fossa was （15. 92±0. 62） mm to posterior clinoids, and the distance of the lahhe vein from temple lobe to the transverse sinus was （2.8±1.3） cm in leftside and （2. 4±1.2）cm in right side. Conclusion： Few vein sinus locates in the inner region and the middle region of the cerebellum tentorium which can he used as the incision site of the tentorium. The posterior portion of the temporal lobe is gently lifted and special attention should he paid to maintain discharge of the oculomotor nerve, the trochlear nerve, the trigeminal sensory root and the lahhe＇s vein into the sinus during operation.
