Methods (1)We observed the serial sheet sections of the optic apex region obtained using collodion microtomy in 4 adult cadaver heads;(2)High resolution CT scanning and three dimensional images of the optic apex region were observed and measured in 10 adult volunteers;(3)High resolution magnetic resonance images of the optic apex region were obse.

①采用火棉胶切片技术对4例(8侧)成人眶尖区标本进行连续薄层断层解剖学观察；②使用高分辨力CT及三维重建技术观测10例(20侧)志愿者眶尖区；③观测5例(10侧)志愿者眶尖区高分辨力MRI断层扫描图像；④对30例(60侧)成人干颅骨标本和15例(30侧)成人湿性头颅标本的眶尖区结构进行显微解剖；⑤在手术显微镜和内窥镜下对3例成人头颅湿性标本模拟眶内经颅入路。

Her height and head girth were excessive. Some degree of psychomotor retardation was present. Physical features included macrocrania, dolichocephaly, frontal bossing, hypertelorism, high-arched palate, large hands and feet. Cerebral ventricles were mildly dilated on brain computerized tomography. The diagnosis lied mainly on clinical characteristics.

最常见的颅面畸形包括额头隆突，高弓腭，两眼过距，长头症，尖下巴和过早发牙，其他较通常的发现还有发展障碍，大手大脚，高骨龄，细微运动调节之缺乏及新生儿适应或餵食困难，本症之诊断主要靠临床诊断，但由於过去在台湾鲜为人所提及，故易与水脑症混淆。

Based on the retrosigmoid approach, the suprameatal tubercle and partial petrosal apex were drilled. The CT and the manual measurements were used for determining the extension of the suprameatal tubercle and petrosal apex in three dimensions before and after the resection of them. The exposed field of the middle fossa and superior clivus and the length of the exposed trigeminal nerve were also measured.

经乙状窦后入路开颅，磨除内耳道上结节和部分岩尖，采用实体和CT相结合的方法测量内耳道上结节、岩尖的切除范围，记录内耳道上结节、岩尖切除前后颅中窝、上斜坡的显露面积和三叉神经的显露范围。

The distance between the line tom the intersecting point of the mandibular nerve and greater superficial petrosal nerve to the lateral lip of the internal acoustic meatus and the porus trigeminus was (8.04±0.99)mm.

颅中窝手术入路操作中，在下颌神经与岩浅大神经交点和内耳门后缘的连线的内侧磨除岩尖部骨质时，不容易损伤耳蜗。

Objective: To explore valuable methods and landmarks for locating cochlea, and provide anatomic data for drilling petrous pyramid during the middle cranial fossa approach.

目的：探讨耳蜗的定位方法和定位标志，为颅中窝手术入路中磨除岩尖及耳蜗在颅底外科的临床应用提供解剖学资料。

Glossopharyngeal Nerve crosses the deep surface of the stylopharyngeus muscle 23 to 47 mm cephalic to the bifurcation of the carotid artery and 7 to 15 mm from the tip of the styloid process .

在颗下窝区，茎突根部、鼓板下缘、寰椎横突、乳突尖以及下领角等可作为舌咽神经颅外部分的参考标志。3在乳突尖到下领角轴线区，切除二腹肌后腹时应注意区别和保护舌咽神经。

A representative from this alien species is a bipedal humanoid with blue-gray skin, double rows of cheekbones, a long, tapered proboscis, four conelets atop the skull, three-fingered hands, and a pair of dark, glassy eyes.

这个人形种族的代表性特征是：两足，皮肤灰蓝，双层的颊骨，尖细的长喙，颅顶生有四个锥角，手上三趾，眼睛黑色透明。
