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。
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。
Conclusion The free nerve endings in the dural root sheaths especially those in the DRG sheath are thought to play an important role in cervical radicular pain. 结论颈神经节两端被膜中大量存在的游离神经末梢在颈神经根性疼痛发病机制中可能起到的重要作用。
