OBJECTIVE: To observe the clinical efficacy of Tongtiao acupuncture-moxibustion method for long COVID-19 olfactory dysfunction. METHODS: A total of 28 patients with long COVID-19 olfactory dysfunction were selected and treated with Tongtiao acupuncture-moxibustion therapy (regulating orifices, invigorating the brain, and regulating qi and blood). Acupoints included Yintang (GV24⁺), Baihui (GV20), Fengfu (GV16), Qihai (CV6) and bilateral Yingxiang (LI20), Fengchi (GB20), Xuehai (SP10), Zusanli (ST36). Deep needling to the periosteum of the nasal bone was performed at Yintang (EX-HN3), with warming needle moxibustion applied. Each treatment lasted 40 min, administered once daily for 6 days per week, followed by a 1-day rest, over 4 consecutive weeks. T&T olfactory test scores, TCM symptom scores, serum cortisol levels, Hamilton depression scale (HAMD) scores, and Hamilton anxiety scale (HAMA) scores were compared before and after treatment. Clinical effect was evaluated based on T&T olfactory test grading. RESULTS: Compared before treatment, the T&T olfactory test scores, each TCM symptom scores, HAMD scores, and HAMA scores were decreased after treatment (P<0.01, P<0.05), while serum cortisol level was increased (P<0.01). The total effective rate was 96.4% (27/28). CONCLUSION Tongtiao acupuncture method could effectively alleviate symptoms of long COVID-19 olfactory dysfunction, increase serum cortisol level, and relieve anxiety and depressive symptoms.
