低频脉冲电诊断在面神经麻痹评定中的应用价值

摘要

Objective To explore the value and significance of low frequency pulse electrodiagnosis to assess facial nerve paralysis.Method Neuromuscular electrical diagnostic instrument was used to detect curves of time intensity for frontalis muscle,orbicularis oculi muscle,orbicularis oris muscle in 50 cases of facial nerve paralysis,150 curves in all.Results In 50 cases of facial nerve paralysis,there were 7 normal patients,31 cases of part degeneration,12 cases of complete degeneration,with the positive rate of 86％.Among 150 curves of time intensity,there were 2l normal curves,96 curves of part degeneration,33 curves of complete degeneration,with the positive rate of 86％.Conclusion It has a certain value and significance of low frequency pulse electrodiagnosis for facial nerve paralysis evaluation.%目的 探讨低频脉冲电诊断对面神经麻痹评定的价值和意义.方法 采用神经肌肉电诊断仪对50例面神经麻痹患者进行强度时间检测,分别检测额肌、眼轮匝肌、口轮匝肌共150条曲线.结果 50例患者,正常7例,部分变性31例,完全变性12例,阳性率为86％; 150条曲线中,正常曲线21条,部分变性曲线96条,完全变性曲线33条,曲线的阳性率为86％.结论 低频脉冲电诊断对面神经麻痹的评定具有一定的价值和意义.
