Treatment of peripheral facial paralysis with acupuncture at Renying (ST 9) mainly cooperated with stellate ganglion block: a randomized controlled trial / 中国针灸

ABSTRACT

<p><b>OBJECTIVE</b>To explore the better therapy for peripheral facial paralysis.</p><p><b>METHODS</b>One hundred and twenty patients were randomized into three groups a common acupuncture group acupuncture at Yangbai (GB 14), Sibai (ST 2) and Yingxiang (LI 20) as main acupoints, a ST 9 group acupuncture at Renying (ST 9) as main and a ST 9 plus SGB group acupuncture at Renying (ST 9) as main cooperated with stellate ganglion block (SGB). Once daily, 7 treatments made one session. After three sessions of treatment, the latency period and amplitude of evoked potential in ENoG, R1 value and R2 value of blink reflex were compared before and after the treatment in different groups separately. The total therapeutic effect was evaluated after treatment.</p><p><b>RESULTS</b>All the treatments shortened the latency period of ENoG, and elevated the amplitude evoked potential significantly. After treatment, the latency period in ST 9 plus SGB group was reduced significantly as compared with common acupuncture group (P < 0.05). The amplitude of evoked potential in ST 9 group was increased significantly as compared with the other two groups (both P < 0.05). After treatment, in each group, R1 and R2 values were shortened significantly. The difference values of R1 and R2 in ST 9 group and ST 9 plus SGB group were all significantly higher as compared with common acupuncture group (both P < 0.05). Additionally, the difference value of R1 in ST 9 plus SGB group was higher significantly than that in ST 9 group (P < 0.05). The clinical cured and remarkably effective rate was 87.5% (35/40) in ST9 plus SGB group, which was higher than 77.5% (31/40) in ST 9 group, and 65.0% (26/40) in common acupuncture group (P < 0.05).</p><p><b>CONCLUSION</b>As compared with common acupuncture group, ST 9 group and ST 9 plus SGB group achieve the much superior efficacy on peripheral facial paralysis. The treatment with ST 9 acupuncture and SGB can better repair the early reflex induced by the injury of facial nerve.</p>
