Abstract
To observe the effect of different acupuncture frequency and duration of needle retention on idiopathic facial paralysis, and optimize the acupuncture treatment plan. A total of 140 patients were randomized into a group A (37 cases, 3 cases dropped off), a group B (35 cases, 3 cases dropped off), a group C (34 cases, 1 case dropped off) and a group D (34 cases, 1 case dropped off). Under the same basic treatment, acupuncture intervention time (day 8 of morbidity), acupoint selection [Cuanzhu (BL 2), Yangbai (GB 14), Taiyang (EX-HN 5), Yingxiang (LI 20), Jiache (ST 6), Dicang (ST 4) on the affected side, Chengjiang (CV 24) and Hegu (LI 4) on the unaffected side] and electroacupuncture intervention, different acupuncture interval time and duration of needle retention were applied. In the group A, the treatment was given 20 min once a day, while the group B 30 min once a day, the group C 20 min once every 2 days, the group D 30 min once every 2 days. Totally 20-day treatment were required. The House-Brackmann (H-B) facial nerve function grading system was used to evaluate the improvement of clinical symptom, the situation and latency periods of the R1 wave in blink reflex and facial nerve motor conduction before and after treatment were observed in the 4 groups. After treatment, the cured rates in the 4 groups were 44.1% (15/34), 46.9% (15/32), 57.6% (19/33) and 51.5% (17/33), there was no significant difference among 4 groups (P>0.05). The situation and latency periods of the R1 wave in blink reflex and latency periods and amplitude of facial nerve motor conduction after treatment were improved in the 4 groups (P<0.01, P<0.05), there was no significant difference among 4 groups (P>0.05). Acupuncture 20 min once a day, 30 min once a day, 20 min once every 2 days and 30 min once every 2 days have significant effect on the recovery of idiopathic facial paralysis, and the effect is comparable.
