目的：探讨强度－时间（Ｉ／ｔ）曲线对周围性面瘫诊断的意义。方法：测定１１６例患者额肌、眼轮匝肌、口轮匝肌的Ｉ／ｔ曲线３３９条，同时比较１５例面神经手术探查情况。结果：在判断Ｉ／ｔ曲线时，时值（Ｃ）和利用时（ＵＴ）具有诊断价值，而基强度（Ｒｂ）无诊断意义，Ｉ／ｔ曲线失神经支配程度与临床表现呈正比，即病情越重，Ｉ／ｔ曲线的变性程度越大，三块肌肉的瘫痪程度及其Ｉ／ｔ曲线变性程度以口轮匝肌最大。结论：Ｉ／ｔ曲线对面瘫具有一定的诊断价值。
Objective: To investigate the significance of intensity-time (I / t) curve in the diagnosis of peripheral facial paralysis. Methods: A total of 339 I / t curves of the frontalis, orbicularis oculi or orbicularis oris of 116 patients were measured, and 15 cases of facial nerve exploration were compared. Results: Time (C) and time of use (UT) had diagnostic value in determining I / t curve, while base intensity (Rb) had no diagnostic significance. The denervation degree of I / t curve was directly proportional to clinical manifestations The more severe the disease, the greater the degree of degeneration of the I / t curve. The degree of paralysis of the three muscles and the degree of degeneration of the I / t curve were the largest in the orbicularis oris. Conclusion: I / t curve has some diagnostic value for facial paralysis.
