摘要
目的:为神经内镜下经胼胝体-穹隆间入路切除第三脑室病变提供相关解剖学资料。方法:在手术显微镜及神经内镜下对25例国人尸头模拟经胼胝体-穹隆间入路,并测量相关解剖学数据。结果:冠矢点下方胼胝体厚度(7.22±0.32)mm,冠矢点前2cm下方穹隆至胼胝体下缘(8.65±1.64)mm,出现透明隔间腔19例(76%),6例中间块缺如(24%)。神经内镜经穹隆间进入第三脑室,脉络丛、前后连合、漏斗隐窝、中间块、中脑导水管开口等是第三脑室的重要"路标"。结论:神经内镜下经胼胝体-穹隆间入路有利于第三脑室和松果体区术野暴露,减少手术损伤,从而最大限度保留正常的解剖和神经功能。
Objective： To offer anatomical data for transcallosal- interforniceal approach in neuroendoscopic surgery. Methods： The relative anatomical structures were observed and recorded in 25 adult antiseptic cadaveric head specimens imitating transcallosal-interforniceal approach by operating microscope and neuroendoscopic. Results： The thickness of callosum was about （7.22±0.32）mm under bregma. The distance was about （8.65± 1.64）mm from fomix to inferior margin of callosum. Camera septi pellucidi was found in 19 cadaveric heads （76%）. Adhesio interthalamica was absent in 6 heads （24%）. The anatomic features of the third ventricle were observed by interforniceal approach. The important ＂road mark＂ in the third ventricle included choroid plexus, anterior and posterior commissure, infundibular recess, interthalamic adhesion, the opening of aqueduetus mesencephali and so on. Conclusions： The structures of the third ventricle and pineal area could be shown clearly by using neuroendoscop.The normal anatomic structures can be protected by transcallosal- inteffomiceal approach under neuroendoscope.
