神经兴奋性试验（NET）及面瘫程度判定在Bel氏麻痹预后评估中作用的比较研究

Comparation between neural excitatory test and prosopoplegic degree judgement on action of prognostic evaluation of Bell's paralysis

作者对５５例Ｂｅｌ麻痹患者发病３周内的神经兴奋性试验（ＮＥＴ）及面瘫程度评分值进行了测定，并观察一年内患者的恢复情况，得出了ＮＥＴ值及面瘫程度判分在Ｂｅｌ麻痹病人预后评估中的作用。结果表明ＮＥＴ判断预后不良以双侧差值３．５ｍＡ为宜。判定预后良好以双侧差值２．０ｍＡ以下为宜。以上两值的评估正确率在９５％以上。而面瘫程度判分在预后的评估中差别较大，如以重度损害１０分以下，面肌残留功能２５％以下为界，准确率只有４３％。故提出在进行Ｂｅｌ麻痹各种疗效评价优劣时，不能只以临床面瘫程度判分来判断患者病情的轻重，而应以电诊检查作为判断病情轻重的依据，以提高各种治疗方法在疗效比较时的可比性。

55 cases of Bell's neural excitatory test (NET) and marking value of prosopoplegic degree in three weeks and the recovery was observed in one year ,which got NET value and prosopsplegic degree judgement point on action of evaluating Bell's paralysis.The results showed that the double's different value is 3.5 mA for NET to judge unfavourable prognosis and below 2.0mA for judging favourable prognosis ,the correct rate is over 95%.The difference is notable on prosopoplegic of judgement point of prosopoplegic degree which the correct rate is only 43%.It is pointed out that the electrodiagnosis can be as basis for judging patients'condition.
