    The fibrous trabeculae were few in most cisterns. Conclusions Fibrous links were few in most lamina terminalis cistern, so it could not be difficult to enter the cistern. But careful and sharp dissection was important between anterior communicating artery and optic nerve/ chiasma.
    结论 多数终板池内纤维连系少,不难进入,但前交通动脉同视神经/交叉间需小心锐性分离。

  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.
      
The subcutaneous fat exhibited an almost echolucent zone with weak echoes from the fibrous trabeculae or large blood vessels.
      
In the early stages, large amounts of granular, yellowish-orange ceroid pigment are frequently found in the proliferating fibrous trabeculae.
      


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 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

Objective: To study the microanatomical characteristics and surgical significance of sphenoidal segment of cistern in lateral fossa of cerebrum (Sylvian cistern). Methods: The anatomical characteristics of sphenoidal segment of Sylvian cistern were observed on 28 sides of cadaveric human head specimens under an operating microscope. Results: Sphenoidal segment of Sylvian cistern was posterior inferior to sphenoidal ridge.It was between front lobe and temporal lobe.Its roof wall was the pia mater lining the...

Objective: To study the microanatomical characteristics and surgical significance of sphenoidal segment of cistern in lateral fossa of cerebrum (Sylvian cistern). Methods: The anatomical characteristics of sphenoidal segment of Sylvian cistern were observed on 28 sides of cadaveric human head specimens under an operating microscope. Results: Sphenoidal segment of Sylvian cistern was posterior inferior to sphenoidal ridge.It was between front lobe and temporal lobe.Its roof wall was the pia mater lining the lowr surface of posterior orbital gyrus.Its wall was the pia mater lining the superior surface of temporal lobe.The posterior pole was the folding line of pia mater lining the inferior wall and superior wall.The medial end was the most space.There were separating membranes between Sylivian cistern and carotid cistern in 57.1% of the specimens.The veins in the cistern varied greatly.Most of superficial middle cerebral veins run in anteriorsuperior part of the cistern.Deep middle cerebral veins run along the posterior inferior aspect of Ml segment of middle cerebral artery or across the compartment of the cistem.The smallest number of fibrous trabeculae in the cistern was more than 10 strips; the greatest number ranged from 30 to 50 strips that arranged in a crisscross pattern.Superior and inferior walls were adhered by short and compact fibrous pieces of membranes anterior to middle 1/3 segment of M1 in 35.7% of Sylvian cisterns. Conclusions: When anterior wall of Sylvian cistern is being cut in pterion approach, it is not easy to injury M1.A quarter of the veins in sphenoidal segment of Sylvian cistern are wrapped up in arachnoid sheath and should not be taken as arachnoid to break.This kind of vein can be identfied by the appearace of well stacked tube like sheath. In separation of superior and inferior walls, the adherence of small area should be sharply sectioned in tangent line.The separating membrane between Sylivain cistern and carotid cistern is not a trustworthy mark of the medial end of Sylvian cistern.

目的 :研究大脑外侧窝池蝶部的显微解剖及其手术意义。方法 :在手术显微镜下观测 2 8侧标本大脑外侧窝池蝶部的解剖结构。结果 :大脑外侧窝池蝶部位于蝶骨嵴后下方及额、颞叶之间 ,顶壁为后眶回下面的软膜 ,底壁为颞叶上面 ,后极为上下壁软膜的反折线。池内侧端最宽大 ,57.%同颈动脉池间存在象片性的隔膜。池内静脉变异较大 ,大脑中浅静脉多行走于池的前上部 ,大脑中深静脉行于M1段后下面或穿行于池中。池内纤维小梁少者仅 1 0余条 ,多者纵横交错达 30~ 50条。 35 .7%池的上、下壁在M1段中 1 /3前方 ,通过短而密的纤维片膜相粘合。结论 :经翼点入路手术中 ,切开大脑外侧窝池前壁时 ,不易伤及M1段主干。大脑外侧窝池蝶部的列脉约 1 /4有蛛网膜鞘包裹 ,勿当作蛛网膜切断 ,可以其饱满的管状鞘膜索样鉴别。分开大脑外侧窝池蝶部上、下壁时 ,小区域粘合处宜沿切线方向锐性切开。大脑外侧窝池与颈动脉池间的隔膜不是池内侧端的可靠标志
