【摘要】：目的研究颅神经微血管减压术的枕下乙状窦后入路相关解剖,为临床手术提供解剖学资料。方法 10%甲醛固定并灌注乳胶的中国人成人头颅湿性标本8例,模拟手术入路,逐层解剖、观察桥小脑角区解剖和主要血管神经,重点研究上、中、下神经血管复合体的解剖和毗邻关系。结果三叉神经入脑干区与乙状窦横窦移行处的距离为(4.4±0.2)cm,面神经出脑干区与乙状窦横窦移行处距离为(4.1±0.2)cm,桥小脑池的宽度为(0.2±0.1)cm,小脑绒球高度为(0.3±0.1)cm。结论通过经枕下乙状窦后入路,解剖桥小脑角区神经血管,研究骨窗、岩静脉,上、中、下神经血管复合体,充分认识各个重要神经和血管结构毗邻关系,对手术有重要指导意义。
[Abstract]:Objective to study the related anatomy of suboccipital retrosigmoid sinus approach after microvascular decompression of cranial nerve, and to provide anatomical data for clinical operation. Methods 10% formalin fixed and perfused latex were performed in 8 Chinese adult cranial wet specimens. Anatomic study of the cerebellopontine angle area and the main vessels and nerves were carried out with emphasis on upper and middle. Results the distance between the trigeminal nerve entering the brain stem and the transposition of the sigmoid sinus was 4.4 卤0.2mm. The distance between the brainstem area of facial nerve and the transposition of sigmoid sinus was 4.1 卤0.2 cm, and the width of pontine cistern was 0.2 卤0.1 cm. The height of cerebellar villus is 0.3 卤0.1 cm. Conclusion the neurovascular complex of bony window, petrosal vein, superior, middle and inferior nerve is studied by transoccipital retrosigmoid sinus approach in the cerebellopontine angle region. It is of great significance to understand the adjacent relationship of the important nerve and vascular structures.
