Objective To explore the best therapeutic method in the treatment of peripheral facial paralysis. Methods One hundred and twenty cases were randomized into a conventional acupuncture group [Yangbai （阳白 GB 24）, Sibai （四白 ST 2）, Yingxiang （迎香 LI 20）, etc.], a Renying （人迎ST 9） acupuncture group and an operation ＋ acupuncture group [acupuncture at ST 9 as the main acupoint and the stellate ganglion block （SGB）], 40 cases in each one. The treatment was given once a day, 7 treatments made one session. After 3 sessions of treatment, the latency and the amplitude of the direct stimulation evoked potential of the facial nerve （ENoG） were compared before and after treatment in three groups, as well as R2 and R2 values of blink reflex （BR）. The total clinical efficacy was assessed. Results The latency of ENoG was shortened and the amplitude was increased significantly in three groups. After treatment, ENoG latency was lower significantly in the operation ＋ acupuncture group as compared with that in the conventional acupuncture group （P〈0.05）. In the Renying （人迎 ST 9） acupuncture group, the amplitude of ENoG was increased as compared with P〈0.05）. After treatment in three groups, those in the other two groups （all R2 and R2 values were decreased significantly. The differences in R1 and R2 values in the Renying （人迎 ST 9） acupuncture group and the operation ＋ acupuncture group before and after treatment were bigger than those in the conventional acupuncture group （all P〈0.05）, and the difference in R2 value in the operation ＋ acupuncture group was bigger than that in the Renying （人迎 ST 9） acupuncture group （P〈O.05）. The clinical markedly effective and curative rate was 87.5% （35/40） in the operation ＋ acupuncture group, which was superior to 77.5% （32/40） in the Renying （）人迎 ST 9）acupuncture group and higher significantly than 65.0% （26/40） in the conventional acupuncture group （P〈0.05）. Conclusion
