To describe an endoscopic perspective of the surgical anatomy of the trigeminal nerve.
Nine adult cadaveric heads were dissected endoscopically.
Opening the pterygopalatine fossa is important because many key anatomical structures (V2, pterygopalatine ganglion, vidian nerve) can be identified and traced to other areas of the trigeminal nerve. From the pterygopalatine ganglion, the maxillary nerve and vidian nerve can be identified, and they can be traced to the gasserian ganglion and internal carotid artery. An anteromedial maxillectomy increases the angle of approach from the contralateral nares due to an increase in diameter of the piriform aperture, and provides excellent access to the mandibular nerve, the petrous carotid, and the cochlea.
Identification of key anatomical structures in the pterygopalatine fossa can be used to identify other areas of the trigeminal nerve, and an anteromedial maxillectomy is necessary to expose the ipsilateral mandibular nerve and contralateral cranial level of the trigeminal nerve.
描述三叉神经外科解剖结构的内镜视角。
对9个成人尸体头部进行内镜解剖。
打开翼腭窝很重要，因为许多关键解剖结构（V2、翼腭神经节、翼管神经）可以被识别并追溯到三叉神经的其他区域。从翼腭神经节可识别出上颌神经和翼管神经，并可将它们追溯到半月神经节和颈内动脉。由于梨状孔直径增加，前内侧上颌骨切除术增加了从对侧鼻孔进入的角度，并能很好地显露下颌神经、岩部颈动脉和耳蜗。
识别翼腭窝中的关键解剖结构可用于识别三叉神经的其他区域，前内侧上颌骨切除术对于显露同侧下颌神经和对侧三叉神经颅段是必要的。
