Clinical Research Of Dangguisini Decoction In Treating Bell Palsy

Objective:To observe the therapeutic effect of dangguisini decoction on the patients suffering from Bell palsy, so as to find new ideas and effective prescriptions. Methods:60 patients with Bell palsy were randomly divided into the treatment group (dangguisini decoction-group n=30) and the control group (Dahuoluo capsules-group n=30). Both were treated for 21 days. And then being compared with their H-B and FDI (including FDIP and FDIS) measuring scale, percentage of the amplitude loss in electroneurography (ENoG) and the latency of R1-wave in blink reflex (BR) before and after the treatment. Results:The statistic analysis revealed that the total effective rate of the treatment group is 90.00%, while the control group is 73.33%. There was significant difference between them (P<0.05). After the treatment, H-B classification and the improvement of FDIP scores in the treatment group are better than the control group (P<0.05). While there was no significant difference in FDIS scoring changes between the two groups (P>0.05). The treatment group can significantly lower the percentage of amplitude loss in ENoG and shorten the latency of R1-wave in BR (P<0.01), better than the control group. Conclusion:Dangguisini decoction can significantly improve symptoms and signs of face, relieve the patients'pain, and can effectively improve facial nerve function, which is an effective prescription in treating Bell palsy.
