Abstract：Objective：To observe the clinical effect of electroacupuncture density wave for facial palsy in acute stage. Methods：A prospective study was conducted on 100 patients with acute facial paralysis， who were divided into the control group and the observation group according to the random number table method，with 50 cases in each group. Both groups received routine symptomatic treatment combined with electroacupuncture； the control group received continuous wave therapy and the observation group received density wave therapy. Both groups were treated for four courses， with 6 consecutive days of treatment and 1 day of rest being one course of treatment. Patients were followed up by phone for 6 months during the sequelae period. The curative effects after follow- up were evaluated in the two groups. The latency time of facial nerve F- wave movement， amplitude of compound muscle action potential (CMAP)，and facial nerve conduction velocity were compared before treatment (T0)，on the first day of recovery period (T1)， and on the first day of sequelae (T2). The facial disability index (FDI) before treatment and after follow- up， and the levels of immunoglobulin A (IgA)， immunoglobulin G (IgG)， and immunoglobulin M (IgM) in serum before and after treatment were compared between the two groups. Results：The total effective rate was 98.00% in the observation group，higher than that of 86.00% in the control group (P＜0.05). At T1 and T2， the F- wave duration and amplitude in the observation group were lower than those in the control group (P＜0.05)，and the nerve conduction velocity on the affected side was higher than that in the control group (P＜0.05). After the follow-up，the physical function scores in the two groups were increased when compared with those before treatment，and the social life dysfunction scores were decreased when compared with those before treatment (P＜0.05)；the physical function score in the observation group was higher than that in the control group，and the social life dysfunction score was lower than that in the control group (P＜0.05). After treatment，the levels of IgA，IgG，and IgM in serum in the two groups were decreased when compared with those before treatment (P＜0.05)，and the levels of IgA， IgG， and IgM in serum in the observation group were lower than those in the control group (P＜0.05). Conclusion：The intervention of electroacupuncture density wave has a good curative effect in patients with acute facial paralysis， which can effectively reduce the degree of facial paralysis， reduce the body's inflammatory response， improve nerve edema， promote nerve injury repair， and thereby improve facial muscle function.
