目的:研究颈内动脉和颅神经之间的关系,为临床解剖提供参考资料。方法:显微镜下对海绵窦进行解剖,将ICA、第Ⅲ、Ⅳ、Ⅴ、Ⅵ颅神经暴露,以观察它们的走行和相互关系,同时使用游标卡尺对相关长度和距离进行测量。结果:颈内动脉和海绵窦内颅神经开始入口平面,颈内动脉共有5个连续部分,三叉神经眼支下缘和滑车神经下缘组成帕金森三角。结论:经帕金森三角区入路,能够将动眼神经的后2/3段和颈内动脉后曲部、后升部以及水平部等很好地暴露出来。对前床突进行磨除时,最好能够在硬膜外进行,有利于保护颅神经。
Objective: To study the relationship between internal carotid artery and cranial nerves and provide references for clinical anatomy. Methods: The cavernous sinus was dissected under the microscope. The cranial nerves of ICA, Ⅲ, Ⅳ, Ⅴ and Ⅵ were exposed to observe their movement and correlation, and the related length and distance were measured by vernier caliper. Results: The internal carotid artery and cavernous sinus cranial nerves began to enter the plane, the internal carotid artery 5 consecutive parts of the trigeminal nerve and the lower edge of the trochlear nerve composed of the lower edge of Parkinson’s triangle. CONCLUSIONS: The posterior parietal segment of the oculomotor nerve, the posterior camber, the posterior ascending portion, and the horizontal portion of the internal carotid artery can be well exposed through the Parkinson’s triangle. Abnormal removal of the anterior bed protrusion, the best can be carried out in the epidural, is conducive to the protection of cranial nerves.
