By staining with toluidine blue and vital staining with methylene blue, the topographical orientation of the stapedial nerve fibers in the facial nerve trunk was visualized in adult guinea pigs. The stapedial nerve with its perineural sheath emerges from the facial nerve trunk in the posteromedial aspect of the upper part of the vertical portion. Toward the horizontal portion, the stapedial nerve fibers gradually ramify, lose their investments, and intermingle with other nerve fibers inside the facial nerve trunk. In the labyrinthine portion, the stapedial nerve fibers are distributed diffusely near the surface along the posterior, medial, and anterior margins of the facial nerve trunk. These findings lead to the conclusion that the stapedial nerve fibers of guinea pigs do not form a single funiculus throughout the intratemporal course of the facial nerve.
通过甲苯胺蓝染色和亚甲蓝活体染色，在成年豚鼠中观察到面神经干内镫骨神经纤维的局部定位。镫骨神经及其神经束膜在垂直部上部的后内侧从面神经干发出。朝向水平部，镫骨神经纤维逐渐分支，失去其被膜，并与面神经干内的其他神经纤维混合。在迷路段，镫骨神经纤维沿面神经干的后缘、内侧缘和前缘在表面附近分散分布。这些发现得出结论，豚鼠的镫骨神经纤维在面神经颞内段全程中不形成单一的索。
