Clinical observation on acupuncture at infusion points of "four seas" on refractory peripheral facial paralysis

Abstract

To observe the clinical effect of acupuncture at the infusion points of "four seas" for refractory peripheral facial paralysis on the basis of conventional acupuncture. A total of 52 patients with refractory peripheral facial paralysis were randomized into an observation group (26 cases, 2 cases dropped out) and a control group (26 cases, 1 case dropped out). On the basis of conventional acupuncture (Yintang [GV 24+] and Yangbai [GB 14], Dicang [ST 4] at affected side, etc.), acupuncture at the infusion points of "four seas", i.e. Baihui (GV 20), Dazhui (GV 14) and bilateral Shangjuxu (ST 37), Xiajuxu (ST 39), Zusanli (ST 36), was delivered in the observation group. On the basis of conventional acupuncture, shallow acupuncture was applied at corresponding non-meridian and non-acupoint points of the infusion points of "four seas" in the control group. The needles were maintained for 30 min, the treatment was given once every other day, 3 times a week for 4 weeks in the two groups. Before and after treatment, the House-Brackmann (H-B) facial nerve grading and the dynamic view score of the facial nerve function scoring system were observed, and the clinical efficacy was evaluated after treatment in the two groups. After treatment, the H-B facial nerve grading was improved compared with that before treatment in the two groups (P<0.05), and the grading in the observation group was superior to that in the control group (P<0.05); the dynamic view scores of the facial nerve function scoring system were increased compared with those before treatment in the two groups (P<0.05), and the score in the observation group was higher than that in the control group (P<0.05). The total effective rate was 91.7% (22/24) in the observation group, and that in the control group was 84.0% (21/25), there was no significant difference in the total effective rate between the two groups (P>0.05). The cure rate was 62.5% (15/24) in the observation group, which was higher than 20.0% (5/25) in the control group (P<0.05). On the basis of conventional acupuncture, acupuncture at infusion points of "four seas" can effectively treat refractory peripheral facial paralysis, improve the facial nerve function and increase the cure rate.
