Efficacy of Needling GB20 with'Wen Tong Acupuncture'in Treatment of Acute Facial Paralysis and Its Influence to Facial Nerve Motor Conduction
Objective:To observe the clinical efficacy difference between needling Fengchi(FB20)with'Wen Tong Acupuncture'and with conventional treatment in treating acute facial paralysis and its impact on facial nerve motor conduction.Methods:70 patients with facial paralysis due to wind-cold attack were randomly divided into the study group and the control group,with 35 patients in each group.The study group was treated with needling GB20 by'Wen Tong Acupuncture',electro-acupuncture(EA)and Western medication;the control group was treated with EA and Western medication.Both groups were observed for 6 weeks maximum,and the treatment would stop if the patient was healed.H-B Scale and Sunnybrook Scale were compared between the two groups before the treatment,after the treatment and during the 3-month follow-up.Clinical efficacy was compared between the two groups after the treatment.Facial nerve motor conduction was compared between the two groups after 2 weeks and after 4 weeks of treatment.The treatment course of the healed cases was compared between the two groups.Results:The grade of H-B Scale and the score of Sunnybrook were significantly improved after the treatment and during the follow-up compared with those before the treatment in the two groups(P＜0.01).The study group was better than the control group in terms of the grade of H-B Scale after 4 weeks of treatment(P＜0.05),but there was no statistical difference between the two groups during the follow-up(P＞0.05).The scores of Sunnybrook were higher in the study group than those in the control group after four weeks of treatment and during the follow-up(P＜0.05).The total effective rate of the study group was 82.86％(29/35)and the remarkable effective rate was 71.43％(25/35),which were significantly higher than 65.71％(23/35)and 45.71％(16/35)of the control group(P＜0.05).The healing rate of the study group was 37.14％(13/35),which was significantly higher than 14.29％(5/35)of the control group(P＜0.01).The healing time was significantly shorter in the study group than that in the control group(P＜0.05).After 4 weeks of treatment,the neuromotor evoked action potential,the latency of orbicularis oculi(ms),the amplitude of orbicularis oculi and orbicularis oris(mv)were significantly different between the two groups(P＜0.01),and the latency of orbicularis oris(ms)were also statistically significant between the two groups(P＜0.05).Conclusion:Compared with the conventional EA plus Western medication therapy,needling GB20 with'Wen Tong Acupuncture'is a more effective method for acute facial paralysis due to wind-cold attack.The method can improve grade of H-B Scale and score of Sunnybrook,increase remarkable effective rate,shorten treatment course and incubation periods of orbicularis oculi muscle and orbicularisoris muscle,and improve their M wave amplitude.
