  fibrous trabeculae
In the articular ends of the false joints, which are often formed after injury of the cerebral cortex, coarse fibrous trabeculae with argyrophil framework are often retained for 200 days.
      
Macroscopically these tumours are usually light brown in colour and commonly exhibit a dense central area of fibrous scarring, with fibrous trabeculae extending from this central zone in a stellate fashion.

Objective:To study the micro anatomical characteristics and related clinical significance of pituitary stalk.Methods:The size,morphology and surrounding structures of pituitary stalk were observed in 15 adult cadaveric heads with an operating microscope.Results:The upper end of pituitary stalk was much thicker than the lower end.The length was about 1 cm.It was abundant in blood vessels.Its appearance was straight,spiral or"V" shaped.Its upper part contained infundibular recess,lower end of which was rather...

Objective:To study the micro anatomical characteristics and related clinical significance of pituitary stalk.Methods:The size,morphology and surrounding structures of pituitary stalk were observed in 15 adult cadaveric heads with an operating microscope.Results:The upper end of pituitary stalk was much thicker than the lower end.The length was about 1 cm.It was abundant in blood vessels.Its appearance was straight,spiral or"V" shaped.Its upper part contained infundibular recess,lower end of which was rather spherical than tapering.There were usually many fibrous trabeculae linking pituitary stalk with surrounding structures.The trabeculae were tigtly crowded between the anterior surface of the upper end of the stalk and optic chiasma.Conclusion:The midpoint of pituitary stalk is always thinner than basilar artery,which can be an important index for diagnosing stalk thickening by image.When operation is performed in chiasmatic cistern,the network of fibrous trabeculae should be managed softly to prevent pituitary stalk from injuring by pulling.In pterion approach,pituitary stalk can be exposed when pushing optic chiasma medially.

目的 :探讨垂体柄的显微解剖特点及相关的临床意义。方法 :采用 1 5个成人尸颅 ,在手术显微镜下观察垂体柄的大小、形态及周围关系。结果 :垂体柄上粗下细 ,平均长度约为 1cm ,血管丰富 ,有径直、“V”形和螺旋状三种形态。其上端含有漏斗隐窝 ,隐窝下端呈圆顶状而非锥状。垂体柄常通过一些纤维小梁与周围结构相连 ,上端前面与视交叉间的连系尤为紧密。结论 :垂体柄中点均较基底动脉细 ,是影像判定垂体柄增粗的重要指标。在视交叉池内操作时 ,对纤维小梁网的处理要轻柔 ,防止垂体柄的粗暴牵拉损伤。经翼点入路手术中 ,内推视交叉利于垂体柄的显露

Objective: To study the microanatomical characteristics and surgical significance of carotid cistern. Methods: The mi-croanatomical characteristics of carotid cistern were observed in 28 sides of cadaveric human heads under an operating microscope. Results: Carotid cistern wrapped up supraclinoid portion of internal carotid artery. The upper wall of the cistern was the bottom of olfactory cistern. The lower wall was the arachnoid covering the upper wall of cavernous sinus. The medial boundary was a layer of...

Objective: To study the microanatomical characteristics and surgical significance of carotid cistern. Methods: The mi-croanatomical characteristics of carotid cistern were observed in 28 sides of cadaveric human heads under an operating microscope. Results: Carotid cistern wrapped up supraclinoid portion of internal carotid artery. The upper wall of the cistern was the bottom of olfactory cistern. The lower wall was the arachnoid covering the upper wall of cavernous sinus. The medial boundary was a layer of arachnoid wall that separated it from the cistern of optic chiasma. The lateral boundary was a layer of arachnoid that separated it from sylvian cistern. There were often some fibrous trabeculae stretching between internal carotid artery and the medial wall of carotid cistern. Internal carotid artery adheres to the arachnoid covering diaphragma sel-lae in a few specimens. A thin branch arose from internal carotid artery to anterior clinoid process in 43% of the specimen. Conclusion: When posterior orbital gyrus and posterior segment of olfactory cistern are raised in pterion approch, the arachnoid which covers anterior clinoid process and anterior petroclinoid fold is shifted medial-superriority. So a man-made lateral-superior wall of carotid cistern is formed. When carotid cistern is being opened, the vessel to anterior clinoid process must be paid attention, because this branch could appear a chorda when it is being pulled. Proper cutting of related fibers could do well to the shift of internal carotid artery.

目的:研究颈动脉池的解剖特征及其手术意义。方法:在手术显微镜下观测28侧尸颅的颈动脉池。结果:颈动脉池包绕颈内动脉床突上段,上壁为嗅池底壁,下壁为铺于海绵窦上面的蛛网膜,内侧与视交叉池常有纤维网壁相隔,外侧与外侧裂池亦常有网膜相隔。颈内动脉与池内侧壁间常有纤维小梁相连,有的与鞍隔上面蛛网膜粘贴。43%的颈内动脉床突上段发出细小的前床突支。结论:翼点入路手术中,抬起眶回及嗅池后部时,亦将覆盖前床突、前岩床皱襞的蛛网膜向上内翻开,形成人为的颈动脉池外上壁。打开颈动脉池时应注意前床突支,可因牵拉而酷似蛛网膜条索。适当的纤维松解有利于颈内动脉的推移。

Objective:To study the construction features and surgical significance of optic nerve and chiasma.Methods:The morphologic characteristics and adjacent relations of optic nerve and chiasma were observed on 15 cadaveric human head specimens under an operating microscope.Results: The length of falciform fold along optic nerve was 0.4~4.6mm.One third of optic nerve bulged.All of the tuberculum sellae were flat.The majority of posterior margins of optic chiasma were posterior to dorsum sella.Optic nerve was mainly...

Objective:To study the construction features and surgical significance of optic nerve and chiasma.Methods:The morphologic characteristics and adjacent relations of optic nerve and chiasma were observed on 15 cadaveric human head specimens under an operating microscope.Results: The length of falciform fold along optic nerve was 0.4~4.6mm.One third of optic nerve bulged.All of the tuberculum sellae were flat.The majority of posterior margins of optic chiasma were posterior to dorsum sella.Optic nerve was mainly supported by superior anterior hypophyseal artery.About half of superior anterior hypophyseal arteries gave out a branch that runs anteriorly along optic never.Superior surface of optic chiasma was supported by anterior cerebral anterior communicating artery complex.Medial part of inferior surface of optic chiasma was mostly supported by superior hypophyseal artery,but lateral part was supported by internal carotid artery and posterior communicating artery.A sheet of arachnoid covered the superior surface of optic nerve.A sheet of pia mater lining inferior surface of gyrus recuts was just superior to the arachnoid.Conclusions: Because the edge of Chinese tuberculum sellae cannot be easily defined,it is difficult to type optic chiasma in traditional methods.So it is proper to judge prefixed optic chiasma or postfixed optic chiasma according to the distance between limbus sphenoidalis and anterior edge of optic chiasms.If a small artery coursing optic nerve was damaged in operation,coagualted must be extraordinarily carefully.Lifting gyrus rectus along optic nerve is a procedure in which dissociaton is done along a less adhesive interface.Fibrous trabeculae presenting in the interface should be cut in half number of cases.

目的 :研究视神经和视交叉的形态结构特点及其临床意义。方法 :在手术显微镜下观测 15个尸体标本的视神经和视交叉的形态特征及毗邻关系。结果 :镰状皱襞沿视神经的长度为 0 .4~ 4.6mm ,1/3的视神经前段隆突 ,鞍结节均较平坦 ,多数视交叉后缘位于鞍背后方。视神经主要由垂体上前动脉供血 ,半数有分支沿视神经前行。视交叉的上面多由前交通动脉复合体供血 ,下面的内侧部多为垂体上动脉供血 ,外侧部多为颈内动脉和后交通动脉的分支供血。视神经上面覆有一层蛛网膜 ,再上面为直回下面的软脑膜 ,二膜间多数分开。结论 :国人鞍结节边界不易确定 ,按传统方法将视交叉分型有困难 ,所以宜按蝶棱与视交叉前缘间距判断前置或后置。手术中易损伤沿视神经行走的小动脉 ,电凝须特别小心。贴视神经上抬直回 ,实际上是沿粘着较少的界面分离 ,有半数需离断一些纤维小梁
