【摘要】：通过探讨正常成人颅脑桥小脑区解剖结构的特点和内窥镜下识别方法及参考标志,及对病理条件下神经内窥镜下桥小脑区解剖结构的特点和识别方法进行比较。为该区的显微手术提供解剖学依据。 具体研究方法为:在8具16侧福尔马林固定的成人尸头标本和4具8侧新鲜成人尸头标本上进行各角度内镜与显微镜对比观察,模拟手术的内镜下血管神经关系的解剖学研究。对15例听神经瘤、1例胆脂瘤,2例三叉神经痛患者显微手术中应用内镜进行该区病理解剖观察。 研究结论为不同角度的内镜在不同层面的观察有独特的作用,30°的内镜既有直视角又有侧视角,尤其适用于观察隐蔽区域,70°的内镜特别适用于听面束行程及内耳道底的观察,并能明确内耳道内容物的关系。可为桥小脑角区解剖提供更多信息。内镜具有侧视角,能越过浅层的阻挡结构,进入桥小脑角深部,观察到手术显微镜下的死角或隐蔽结构,尤其重要的是,无需干扰任何结构,即可明确神经血管之间的关系。应用神经内镜观察桥小脑区病理条件下解剖结构的特点和识别方法,为该区的病变的显微外科治疗提供了解剖学基础,可指导临床操作。
[Abstract]:The characteristics of anatomical structure of cerebellopontine area in normal adults and the identification methods and reference markers under endoscope were discussed. The characteristics and recognition methods of anatomical structure of cerebellopontine area under neuroendoscopy were compared. To provide anatomical basis for microsurgery in this area. The specific methods were as follows: 8 adult cadaveric head specimens fixed with formalin and 4 fresh adult cadaveric head specimens were examined with different angles of endoscopy and microscope. The anatomic study of vascular and nerve relationship under endoscope was carried out on the simulated operation of 8 adult cadaveric heads and 4 fresh adult cadaveric heads. 15 cases of acoustic neuroma, 1 case of cholesteatoma and 2 cases of trigeminal neuralgia were studied by endoscopy. The conclusion is that endoscopy at different angles has a unique effect on different levels of observation. A 30 掳endoscope has both a straight and a lateral angle of view, which is especially suitable for observing the concealed area, and a 70 掳endoscope is especially suitable for observing the distance of the auditory surface bundle and the bottom of the inner auditory canal. The relationship between the contents of the inner ear canal and the contents of the inner ear canal can be clarified. It can provide more information for the anatomy of cerebellopontine angle area. The endoscope has a lateral angle of view and can cross the shallow barrier structure into the deep part of the cerebellopontine angle and observe the dead angle or concealed structure under the surgical microscope. It is especially important that the relationship between the nerve and blood vessels can be clarified without interfering with any structure. The anatomical structure of cerebellopontine area under pathological conditions was observed by neuroendoscopy, which provided anatomical basis for microsurgical treatment of the lesions, and could be used to guide clinical operation.
