目的 观察家兔面神经急性损伤后髓鞘和轴索的组织病理变化。方法 用丝线结扎茎乳孔以外的面神经总干，观察结扎后1天、3天及5天面神经的组织病理改变。结果 家兔面神经受损后，先后在髓鞘和轴索出现轻重不等、程度不同的形态学改变。结论 结扎家兔面神经后，其髓鞘及轴索会出现相应的病理改变，且随着结扎天数的增加，面神经损伤亦呈加重的趋势。
目的 觀察傢兔麵神經急性損傷後髓鞘和軸索的組織病理變化。方法 用絲線結扎莖乳孔以外的麵神經總榦，觀察結扎後1天、3天及5天麵神經的組織病理改變。結果 傢兔麵神經受損後，先後在髓鞘和軸索齣現輕重不等、程度不同的形態學改變。結論 結扎傢兔麵神經後，其髓鞘及軸索會齣現相應的病理改變，且隨著結扎天數的增加，麵神經損傷亦呈加重的趨勢。

Objective To investigate histopathological changes of acutefacial nerve impairment. Methods Ligation of facial nerve outside stylomastoid foramen with 3-0 silk, observation of histopathological changes of facial nerve on the 1st day, 3rd day and 5th day after ligation. Results The facial nerve showed all kinds and various degrees of histopathological changes, from swelling to degeneration, in myeline and axon respectively. Conclusion All kinds and various degrees of pathological changes have been observed in myeline and axon after the ligation of facial nerve in rabbits. This study demonstrates that such injuries to the facial nerve become increasingly serious as the ligation lasts day after day.
