【摘要】：第—部分 内窥镜下经口咽入路至中下斜坡应用解剖学研究 目的 研究内窥镜下经口咽入路至中、下斜坡局部解剖学并测量相关解剖数据，为临床手术提供形态学依据。方法 交替使用手术显微镜和0°、30°硬质内窥镜研究10例成人尸头，探讨经口咽至中下斜坡手术入路；测量与入路相关的60具成人颅骨标本数据。结果 斜坡常规开窗20mm*30mm，插入内窥镜和各种手术器械，，研究对应脑干侧前方的解剖结构；沿途“路标”构成的路线图为：口咽→咽后壁软组织→骨性标志(枕骨大孔前缘→下斜坡→咽结节→中斜坡)→硬脑膜→非骨性标志(Ⅵ-Ⅱ颅神经、椎基底动脉及其分支，以及其之间解剖毗邻关系)；切牙孔、前鼻棘、后鼻棘、卵圆孔、破裂孔、颈动脉外口及舌下神经管外口的内侧缘至咽结节及后四项至中线的距离分别为(mm)：(71.0±4.1)、(78.3±4.3)、(33.7±4.3)、(27.2±2.1)、(13.2±2.0)、(25.7±2.3)、(19.7±1.3)、(23.3±2.1)、(10.5±2.0)mm、(25.2±3.7)、(17.2±2.7)。结论 应用内窥镜经口咽入路可完成中下斜坡脑干腹侧部位病变的手术治疗，以处理椎基底动脉瘤及体积较小且血供一般的病变为佳。
[Abstract]:Applied Anatomical study of part-part Endoscopic approach from oropharynx to Middle and Lower ClivusObjective to study the local anatomy of middle and inferior Clivus via oropharynx approach under endoscope and measure the relevant anatomical data to provide morphological basis for clinical operation.Methods 10 adult cadaveric heads were studied by using surgical microscope and 0 掳30 掳rigid endoscope. The operative approach from oropharynx to middle and lower Clivus was studied, and the data of 60 adult cranial specimens related to the approach were measured.Results the slope was routinely fenestrated 20 mm to 30 mm and inserted into endoscope and various surgical instruments to study the anatomic structure of the anterior side of the brain stem.The road map of the "road sign" along the way is as follows: the soft tissue of the posterior wall of oropharynx and pharynx (the anterior margin of the occipital foramen below the Clivus tuberculus middle Clivus) and the non-osseous mark of dura mater (鈪
