[Modified acupuncture at sphenopalatine ganglion for allergic rhinitis: a randomized controlled trial].

Objective: To observe the effect of modified acupuncture at sphenopalatine ganglion for allergic rhinitis (AR).

Methods: A total of 80 patients with AR were randomly divided into an observation group and a control group, 40 cases in each group. In the observation group, modified acupuncture at sphenopalatine ganglion was given, 30 min each time, 2 times a week and with an interval of 3-4 days. In the control group, budesonide nasal spray was given. Both groups were treated for 4 weeks. The total nasal symptom score (TNSS) and total non-nasal symptom score (TNNSS) were observed before treatment, after first treatment, after last treatment and 4 weeks after treatment; the scores of visual analogue scale (VAS) and rhinoconjunctivitis quality of life questionnaire (RQLQ) were observed before treatment, after last treatment and 4 weeks after treatment; the recurrence condition was evaluated 4 weeks after treatment; the clinical efficacy was evaluated after last treatment in the two groups.

Results: Compared with before treatment, the total scores and each score of TNSS, TNNSS scores after first treatment, after last treatment and 4 weeks after treatment were decreased in both groups (<0.01, <0.05). After first treatment, the total score, stuffy nose score, itchy nose score of TNSS and TNNSS score in the observation group were lower than the control group (<0.01, <0.05). After last treatment, the total score, stuffy nose score, itchy nose score of TNSS in the observation group were lower than the control group (<0.01). Four weeks after treatment, the total score and each score of TNSS, TNNSS score in the observation group were lower than the control group (<0.01, <0.05). Compared with before treatment, the scores of VAS and RQLQ after last treatment and 4 weeks after treatment were decreased in both groups (<0.01), and those in the observation group were lower than the control group (<0.01). The recurrence rate was 13.5% (5/37) in the observation group, which was lower than 44.8% (13/29) in the control group (<0.01). The total effective rate was 92.5% (37/40) in the observation group, which was higher than 72.5% (29/40) in the control group (<0.05).

Conclusion: Modified acupuncture at sphenopalatine ganglion could effectively improve symptoms and quality of life in patients with AR, and the recurrence rate is lower.
