MRI Anatomy and Neurovascular Relationships of the Proximal Cisternal Segment of the Trochlear Nerve

脑池段滑车神经的MRI影像解剖及神经血管关系

The nerve lay in 4.5 ± 2.1 mm medial to trochlear nerve in the middle part of cavernous sinus .

在窦的中部，位于滑车神经内侧4.5±2.1mm。

The course of the intra-cavernous trochlear nerve had three types : straight , convex and intercrossed type .

滑车神经CS段行程形状分三型：直型、凸型和交叉型。

The sheath of internal carotid artery is also the landmark for the entrance site of the oculomotor and trochlear nerve .

颈内动脉鞘亦可以作为动眼神经入口和滑车神经入口的标志点。

Microsurgical Anatomy of Trochlear Nerve

滑车神经的应用显微解剖研究

The vertical distance from the point of trochlear nerve entering CS to ophthalmic nerve was ( 5 52 ± 1 06 ) mm .

滑车神经入窦点与眼神经垂直距离为（552±106）mm。

And measure the cisternal segment of oculomotor nerve , trochlear nerve , trigeminal nerve , abducent nerve and facial nerve .

以及测量动眼神经、滑车神经、三叉神经、展神经、面神经脑池段。

The point of intersection of post bedrock folds and tentorial edge can be targeted the point of Trochlear nerve into the tentorial .

后岩床皱襞与小脑幕缘的交点为标志点可定位滑车神经入小脑幕点。

Conclusion Use of 3D-CISS and 3D-TOF sequences enables accurate identifying the proximal cisternal segment of the trochlear nerve and its neurovascular relationships .

结论3D-CISS序列结合3D-TOF序列能清楚显示脑池段滑车神经的走行特点及神经血管关系。

Conclusions The trochlear nerve should be protected through the space between superior oblique and the superior levator , rectus muscles into the optic and orbital apex .

结论经颅开眶，在上斜肌与上睑提肌、上直肌之间的间隙入路手术时应注意保护滑车神经。

Objective : To study the microanatomy of trochlear nerve for purpose of searching the anatomical landmarks of the entrance site of trochlear nerve in the middle incisural space .

目的：通过滑车神经行径特点的显微解剖，寻找天幕裂孔侧方区域滑车神经入口的定位解剖标志点。

Results ( 1 ) The trochlear nerve entered into the orbital side of one third of superior oblique muscle , it was neighboring frontal nerve when it crossed superior levator muscle ;

结果（1）滑车神经多在上斜肌后1/3段的眶面入肌，在滑车神经与上睑提肌交叉处，额神经紧邻滑车神经外侧；

The trochlear nerve and the superior division of oculomotor nerve were ( 0.35 ± 0.12 ) mm and ( 0.39 ± 0.22 ) mm inferior to the upper margin of SOF respectively ;

滑车神经和动眼神经上支距眶上裂上壁下缘分别为（035±012）mm和（039±022）mm；

Objective To obtain MRI sectional anatomical data of the proximal portion of the cisternal segment of the trochlear nerve , and to assess the anatomical features and vascular relationships of the trochlear nerve .

目的获得滑车神经的MRI断层影像解剖资料，研究滑车神经的解剖走行特点及与神经血管关系。

Result : There are 9 cases of oculomotor nerve palsy , 3 cases of abducens nerve palsy and 1 case of trochlear nerve palsy in the total 15 cases . The rest 1 case have both oculomotor and abducens nerve paralysis .

结果：15例患者均为单眼，单动眼神经麻痹9例，单外展神经麻痹3例，单滑车神经麻痹1例，动眼神经合并外展神经1例，15例患者瞳孔均正常。

Results 3D-CISS MR imaging depicted the proximal cisternal segment of the trochlear nerve in the transverse , sagittal , and coronal planes in 74 ( 93 % ), 66 ( 82 % ) and 63 ( 79 % ) of 80 nerves respectively .

结果80条滑车神经在横断位、矢状位、冠状位分别以74条（93%）、66条（82%）和63条（79%）的几率显示。
