Abstract

Background

Allergic rhinitis is a common respiratory disease. Acupuncture is used to treat it in traditional Chinese medicine, and generally, the L120, ST2 and ST36 acupoints are selected in clinical practice. We report a new method of acupuncture at the sphenopalatine acupoint (SPA) for treatment of persistent allergic rhinitis (PAR). The effect of this treatment was investigated using two different needling depths. The efficacy of this treatment was associated with accurate stimulation of the sphenopalatine ganglion (SPG).

Methods/Design

A total of 61 patients diagnosed with PAR were randomly allocated to either the acupuncture or the sham acupuncture group. The difference between the groups was the needle depth when acupuncture was administered, which was 50 mm and 20 mm. Alteration in total nasal symptom score (TNSS) was the primary outcome. Quality of life, medication dosages and adverse events were secondary outcomes, measured using the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ). Confidence assessment was performed to evaluate data from the treatment and follow-up periods.

Results

Results were: (1) average TNSS in the treatment group was significantly lower than in the control group at week 4 (median and 25th and 75th percentiles were 5.00 (4.00, 7.00) and 8.00 (7.00, 10.00), respectively (P < 0.001)). However, scores in the two groups were not significantly different at week 12; (2) quality of life (RQLQ) was significantly improved at week 2 in the treatment group compared to the control group (scores of 35.47 ± 8.20 and 45.48 ± 8.84; P < 0.001); (3) during the follow-up period, the medication dosage in the treatment group was much lower than in the control group (3.64 ± 1.45 and 6.14 ± 2.34; P < 0.05); and (4) no adverse events were observed in either group during treatment.

Conclusions

This pilot study revealed a profound effect of acupuncture at the SPA on prevention of PAR development. The TNSS in the treatment group (needle depth 50 mm), was significantly lower than in the control group (needle depth of only 20 mm). Our result demonstrates that performing acupuncture directly at the SPA to stimulate the SPG is an effective method to treat PAR.
