The Primary Study Of Judging The Degree Of Nerve Injury For Idiopathic Facial Paralysis By Electroacupuncture

Objective: To explore a simple and convenient clinical method for evaluating degree of facial nerve injury,as well as a complementary method for testing facial nerve function. Methods:1. Medical Literature SearchingSummarized the knowledge of diopathic facial paralysis,the present searching situation of evaluating system and testing method about the facial nerve function, after reviewing a great deal of medical literature related to ancient and modern TCM and Western Medicine, both in and abroad.2. Clinical StudySelected 71 cases of diopathic facial paralysis, which were divided into 3 groups: light, middle and severe degree according to the compound muscle action potential amplitude of the facial muscle on the affected side. Measured the change of electroacupuncture stimulation intensity on healthy and affected side of facial muscles, analyzed the data, then the correlation between the concerned indexes and the consistency of the concerned results were evaluated.Results:1. 71cases of the diopathic facial paralysis were divided into 3 groups according to the result of ENoG : group A (light), group B (middle) and groupC (severe). Eliminated 6 cases according to the eliminating standard. Counted 65 cases in the statistic range. The various data among the 3 groups were compared as follows:â‘ Age,gender construction:no significant deviation (P>0.05);â‘¡Level of increased extent of electroacupuncture stimulation intensity: group C > group B > group A (respectively,p<0.001,for all)2.In subjects of diopathic facial paralysis in this study, N(variant extent of electroacupuncture stimulation intensity) were significantly negatively correlated with M(the level of compound muscle action potential amplitude of the facial muscle on the affected side)(P< 0.001)3.The graduation of the variant extent of electroacupuncture stimulation intensityResult of the Roc Curve:the boundary between degree 1 and degree 2 was 69.05% while between degree 2 and degree 3 was 87.08%.4.The consistency of the results in electroacupuncture stimulation test and ENoG is quite good, while the discrepancy between them is distinctive. (K=0.793,p<0.001)Conclusions:The electroacupuncture stimulation of facial points can approximately reflect the degree of facial nerve injury in diopathic facial paralysis, which is consistent with the result of ENoG on the whole. This method is so simple and convenient that it can also be a complementary method for testing facial nerve function in clinic.
