To explore the clinical effect of Jingjin needling method in the treatment of refractory peripheral facial paralysis from multiple dimensions.

From January 2017 to December 2018, 110 patients with intractable facial paralysis who met the inclusion criteria of this study were selected the outpatient and inpatient department of acupuncture and moxibustion department of Chongqing traditional Chinese medicine(TCM) hospital, and randomly divided into treatment group and control group, including 55 patients in each group. The treatment group were treated with Jingjin needling method, and the control group were treated with facial three-line needling. The course of treatment was 4 weeks. The TCM symptom and sign scale was used to evaluate the clinical efficacy. The rank sum test was used to compare House-Brackmann (H-B) facial nerve function grading (H-B grading) score and clinical efficacy between the two groups before and after treatment. The Chi-square test was used to compare the incidence of facial paralysis complications between the two groups after treatment for 4 weeks. At the same time, the two groups were examined by facial electroencephalogram (ENoG).

(1) According to House-Brackmann scale both group had symptom improvement(Z=-6.083, -2.089, all P<0.05), and trial group was significant superior to control group (Z=-3.580, P<0.05). (2) There were significant differences between the treatment group and the control group in the efficacy of patients with different H-B grades(χ²=15.107, 8.953, all P<0.05), and the treatment group was significant superior to control group in the patients with level VI(χ²=0.025, P<0.05). (3) After treatment, the score of TCM symptoms in the treatment group was (7.85±3.26), which was significantly lower than that in the control group (12.57±4.18) (t=-6.068, P<0.05). (4) The treatment group(5.77%) had less complications than control group(19.61%) (χ²=4.471, P<0.05). (5) After treatment, two groups had no significant difference according to ENoG(Z=-0.415, P>0.05).

Acupuncture can obviously improve the symptoms of patients with refractory peripheral facial paralysis and reduce the incidence of facial paralysis complications. The Jingjin needling method curative effect is superior to facial three-line needling method. The ENoG by testing the neural function of refractory facial paralysis may have certain hysteresisand may not be suitable for the evaluation criteria of curative effect in patients with refractory peripheral facial paralysis.
