【摘要】 目的为了研究创伤性面神经损伤动物模型的神经电图（Electrograph,ENo）改变.方法我们对68只家兔136侧面神经颊面干分别造成六种常见损伤，测定伤后不同时间ENoG。结果结果显示，ENoG反应的恢复时间随损伤程度的加重而延迟，恢复达正常的时间也相应延迟；其中，损伤后即刻测定牵拉、压榨、挤压3组轻中度损伤，ENoG各指标与正常对照值无显著性差异；除90天外，一定时间各损伤ENoG表现差异显著；除暴露组外各损伤不同时间相同指标有显著差异。结论我们认为家兔创伤性面神经损伤的ENoG改变模型有一定临床诊断价值.更多还原

【Abstract】 Objective To study the electrography (ENod ) change of the experimental animal model ontraumatic facial nerve injury. Methods Six patterns of injury (exposure , comperssion , crushing, stretching, division andpostdivision anastomosis were created in 136 sides of facial nerve buccal branches in 68 rabbits and changes of ENoG aldifferent time intervals were studied. Results The more severe the injury was, the longer time it took to respond toENoG.There wase no significant ENoG difference between the normal control group and the slight and medium injurygroups when determined immedialely after injury. Significant ENoG difference was found in different injuries at all timeintervals except at 90 days. The same index at different time intervals showed significant difference except in exposure injury.Conclusion The experimental animal model of ENoG on traumatic facial nerve injury is helpful for clinicaldiagnosis.更多还原
