Results:(1) Spin-echo sequence included axial, coronal and sagittal images. In T1-weighted images,the medulla oblongata is isointense,the cistern is hypointense; in T2-weighted images,the medulla oblongata is isointense, CSF shows hyperintense, and the arteries of posterior fossa appear hypointense flow voids. The cisternal cranial nerves are not clearly demonstrated in the routine spin-echo images. In 3D-time of flight images, the brain tissue shows isointense, CSF is hypointense, the artery shows hyperintense,and the cranial nerves show linear isointense.

2，结果：(1)常规SE序列横断面、冠状面及矢状面T1WI显示延髓等脑组织呈等信号，延髓周围池脑脊液呈黑色低信号，T2WI显示脑组织为等信号、脑脊液为白色高信号，脑底动脉在池内高信号背景下由于&流空效应&而表现为低信号，常规序列由于成像参数关系而不能直接显示脑池内颅神经；三维时间飞跃(3D-TOF)成像序列显示脑组织为等信号，脑脊液为低信号，而脑池内脑底动脉则呈高信号、脑池内后组颅神经为线状等信号。

Results:(1)The Anterior clinoid process is a posterior and medial continuation.

By drilling the anterior and posterior clinoid process in the orbitozygomatic-cavernous sinus approach, the exposure of superior segment of the basilar artery can be increased.

在经眶颧-海绵窦入路手术中磨除前床突和后床突，可增加对基底动脉上段的显露。

Results The superior wall of cavernous sinus, longitudinal trapezoid in shape, was limited laterally by anterior petroclinoid ligament and lateral margin of anterior clinoid process, and medially by the dura of the diaphragma sellae, anteriorly by the base of anterior clinoid process and the falciform dural fold, and posteriorly by the posterior petroclinoid ligament.

结果 海绵窦上壁呈纵长的四边形。外侧界为前床岩韧带和前床突外缘；内侧界为鞍隔的硬膜缘；前界为前床突基底部和镰状硬膜皱褶；后界为后床岩韧带。

Along the membrane, the cavernous sinus can be reached. After drilling the posterior clinoid process, exposing the dorsum sellae and the upper clivus, the superior segment of the basilar artery can be exposed.

结果 磨除前床突后形成的间隙为床突间隙；前床突下颈内动脉与动眼神经间的膜为颈内动脉动眼神经膜，沿此膜可进入海绵窦；磨除后床突后，暴露鞍背、上斜坡，即可显露基底动脉上段。

Results With orbitozygomatic approach, drilling the anterior clinoid process got a space called the clinoid space. The membrane between the internal carotid artery beneath the anterior clinoid process and the oculomotor nerve is called carotidoculomotor membrane. Along the membrane, the cavernous sinus can be reached. After drilling the posterior clinoid process, exposing the dorsum sellae and the upper clivus, the superior segment of the basilar artery can be exposed.

结果 磨除前床突后形成的间隙为床突间隙；前床突下颈内动脉与动眼神经间的膜为颈内动脉动眼神经膜，沿此膜可进入海绵窦；磨除后床突后，暴露鞍背、上斜坡，即可显露基底动脉上段。

Grinding the ossea of the Kawase triangle can expose clivus from the floor of the middle cranial fossa and come into posterior cranial fossa.

磨除Kawase三角的骨质可以从中颅窝底暴露上中斜坡，从中颅窝底进入后颅窝，可以施行椎动脉瘤的夹闭术。

Comclusion: transpetrous presigmoid retrolabrinth approach was rational approach for surgery on petroclivus and -4- CPA; it抯 important for accomplish the surgery to study and master the anatomy and variance of this approach; there was relative anatomical relationship among those structure on posterior of petrous bone; AAMP was the extracranial mark of inflexion of TS and SS; LAM and PSC were obvious bone marks for operation; we can confirm the abraded range of petrous bone lean upon LAM and/or GSS beside abrading step by step as literature, and it抯 unnecessary and unrational to emphasize to show PSC if the surgical space was enough; preceding sigmoid sinus and high jugular bulb often appeared at right and would bring disadvantage effect; interspace ,between CN V and CNVII or CNVII and CNJXI, were available to reach clivus and manage the mass on the range.

经SS前迷路后入路是处理岩斜坡区、桥小脑角区病变理想的手术入路；研究和熟悉手术入路中的解剖结构及部分变异对指导手术十分必要；岩骨内测面的骨性结构之间有着相对稳定的空间关系；顶乳缝前角是SS和TS转接处在颅外的标志；IAM和PSC等结构可以作为手术中的重要骨性标志；以PSC确定岩骨的磨除范围是较安全和可靠的，但亦可以结合影像检查，以内耳道和乙状窦前缘为基点判定切除范围，如果操作空间足够，过分强调磨出半规管是不适当的；右侧GSS的宽度和深度较对侧大，SS前置和颈静脉球高位较对侧多见，这些都对右侧入路有不利的影响，但仍可以进行手术操作；三叉神经和面神经间隙及面l 神经和舌咽神经间隙方便到达斜坡并处理病变。l
