ABSTRACT
OBJECTIVE: The purpose of the present study was to investigate the effect of acupuncture on xerostomia in irradiated patients with head and neck squamous cell carcinoma (HNSCC). STUDY DESIGN: A preventive, 2-arm, parallel, single-blind trial was performed. Patients with HNSCC (N = 296) were checked for eligibility, and 107 patients were enrolled in the study. The study comprised 1 group that did not receive the intervention (n = 55) and the interventional group that received traditional and auricular acupuncture (n = 52). The primary outcome was the reduction of the patients' xerostomia after treatment. In addition, the secondary outcome was the reduction of anxiety. RESULTS: The current acupuncture protocol reduced the xerostomia score and increased saliva volume and density without changing salivary pH. Additionally, acupuncture decreased the Beck Anxiety Inventory (BAI) score after radiation therapy. CONCLUSION: Combining traditional and auricular acupuncture reduced xerostomia and increased saliva volume without changing the saliva's pH in irradiated patients with HNSCC. Additionally, the combination of traditional and auricular acupuncture reduced BAI scores.
