dural sheath

Objective To find out the distribution of nerve endings in the dural sheath of cervical nerve roots and to study the mechanism of cervical radicular pain.

目的调查人颈髓神经根硬膜性被膜内神经末梢的数量分布，探讨颈神经根性疼痛的发病机制。

Results The distance from the temporal tip dural fold to the nerve-vascular common sheath of SOF was 5.52 ± 1.09 mm.

结果从颞极硬膜索带外侧缘到眶上裂神经血管共同鞘的距离为5.52±1.09mm。

OCT width could be increased doubly by opening the roof of the optic canal and incising dural sheath of optic nerve, with allowable retraction on the mobilized optic nerve medially.

打开视神经管上壁及视神经硬膜鞘后，向内侧轻轻地牵拉可移动的视神经，在OCT的宽度方面能增加接近2倍。
