【摘要】：目的:为微血管减压术治疗三叉神经痛、面肌痉挛和舌咽神经痛选择适当的手术入路提供解剖依据,以达到微创、安全的目的。方法:十例成人头颅湿性标本在手术显微镜下进行解剖和观察。分别选择枕下乙状窦后入路经小脑幕面侧方到达位于桥小脑角上部的三叉神经;枕下外侧入路经小脑岩面下部到达位于绒球下的面神经根;枕下经髁上入路经小脑枕面到达位于桥小脑角下部的舌咽神经。结论:选择不同的手术如路可精确地到达桥小脑角的不同部位,同时最大程度地减少术后颅神经瘫痪。
[Abstract]:Objective: to provide anatomic basis for microvascular decompression in the treatment of trigeminal neuralgia, hemifacial spasm and glossopharyngeal neuralgia. Methods: ten adult head wet specimens were dissected and observed under surgical microscope. The posterior sigmoid sinus approach was selected to reach the trigeminal nerve located in the upper part of the cerebellopontine angle through the lateral side of the tentorial surface of the cerebellum, and the lateral approach of the suboccipital approach to the root of the facial nerve in the subtrochanteric region through the lower part of the cerebellar lithoid. The supracondylar approach leads to the glossopharyngeal nerve at the lower part of the cerebellopontine angle through the occipital surface of the cerebellum. Conclusion: different surgical approaches can accurately reach different parts of the cerebellopontine angle and minimize postoperative cranial nerve paralysis.
