After injury to the intracranial portion of the facial nerve, undegenerated myelinated nerve fibres were seen to form a distinct bundle in the peripheral part of the transverse fascicular area at the level distal to the geniculate ganglion. The numbers and diameters of the fibres were similar to those seen in the nervous intermedius portion of the facial nerve in experimental animals. The average number of these apparently non-motor fibres was 2500. Their average diameter was 2.4 micrometer.
面神经颅内段损伤后,在膝状神经节远侧水平的横束状区域周边部分,可见未退化的有髓神经纤维形成一个独特的束。这些纤维的数量和直径与实验动物面神经中间神经部分所见相似。这些明显非运动性纤维的平均数量为2500条。它们的平均直径为2.4微米。
