目的:研究三脑室的神经内镜解剖学特点,探讨其临床应用价值。方法:在15例尸颅标本、10例脑积水患者手术中用神经内镜观察三脑室的解剖结构。其中在尸颅标本采用经侧脑室额角、枕角和三脑室后部入路观察脑室;在脑积水患者中均采用经额角入路。结果:经额角入路可以观察三脑室底部、后部;经三脑室后部可以观察三脑室前壁的漏斗隐窝、视交叉隐窝和A2。结论:经额角入路观察范围最大,是到三脑室内神经内镜手术的最常用入路,经此入路可以同时完成多种手术。经三脑室后部是观察三脑室前壁的最佳角度。
Objective: To study the neuroendoscopic anatomy of the third ventricle and to explore its clinical value. Methods: The anatomic structures of the third ventricle were observed with neuroendoscopy in 15 cases of cadaveric skull specimens and 10 cases of hydrocephalus. Including in the corpse cranial specimens by the lateral forehead forehead, occipital horn and three ventricle posterior approach to observe the ventricle; in patients with hydrocephalus are by forehead approach. Results: The bottom of the third ventricle and the posterior part of the third ventricle can be observed by forehead approach. The anterior crypt of the third ventricle can be observed by the posterior part of the third ventricle. Conclusion: The largest observation range by the forehead is the most common approach to endoscopic neurosurgery in the third ventricle. After this approach, multiple operations can be completed simultaneously. After the third ventricle is the best observation of the anterior third ventricle wall angle.
