The two most commonly used surgical techniques to setback a prognathic mandible include the bilateral sagittal split osteotomy and the vertical ramus osteotomy 二种最普遍使用正颚手术方法来改善下颚骨前突症的方法是双侧矢向面骨切开术及垂直下颚枝骨切开术。
Objective : to study the chordae and arachnoid granulations in the lumen of superior sagittal sinus and torcular herophili by endoscope and microscope 摘要目的：通过内窥镜及显微镜观察成年人上矢状窦、窦汇窦腔及其内的纤维索、蛛网膜颗粒结构的解剖学形态特征。
Choosing appropriate angled pedical screws according to preperative measurements , rf can always create sagittal physiologic curvature which is planned tocreate preoperatively 只要根据手术前的计划及测量，选择适当角度的椎弓根钢钉就可创造出所需要的生理曲线。
Results : the chordae in the lumen of superior sagittal sinus was divided into three types : valvelike ( 47 . 1 % ) , trabecular ( 30 . 6 % ) and lamellar ( 22 . 3 % ) 上矢状窦最后段近窦汇区有纵行板层状纤维索结构，将上矢状窦最后段管腔分为左右两个单独管道，有分流和支撑作用。
Many descriptions are made using imaginary planes passing through the body in the anatomical position . there are median , sagittal , coronal and horizontal planes 人们根据解剖方位，设想有多个平面贯穿人体，并由此作出多种描述，即正中面、矢状面、冠状面和水平面。
The sagittal planes . these are any vertical planes passing through the body parallel to the median plane . these sagittal planes divide unequally the body to right and left portions 矢状面。与正中面平行、贯穿人体的垂直面。矢状面将人体分为不对待的左、右两部分。
Conclusions : comparing with routine anatomy method , endoscope is better in studying the integrity characteristic of structure of superior sagittal sinus and torcular herophili directly 结伦：内窥镜较常规解剖手段可以更直接地观察窦汇及上矢状窦腔内结构的完整形态特征。
Summary of background data . although arious cerical sagittal alignment assessment methods are widely used , their relatie reliability and intercorrelation hae not been reported 背景资料的摘要：虽然不同的颈椎矢状面评估方法被广泛应用，他们的相关可靠性和相关性还没有被报道。
Objectie . the aim of this study was to obtain proteoglycan distribution in human lumbar discs with high position resolution in the : 1 ) sagittal , 2 ) coronal , and 3 ) axial directions 目的：本实验的目的是获得蛋白多糖在人类腰椎间盘矢状位、冠状位和轴状位上分布的高解析度位置。
This magnetic resonance imaging ( mri ) scan of the pelvis in sagittal view demonstrates a large discreet leiomyoma of the upper posterior myometrium , seen just anterior to the rectosigmoid colon Mri示盆腔矢状面，于后上方子宫肌层可见一体积大，界限清楚的子宫肌瘤，后方紧邻乙状结肠。
