Effect of Auricular Point Acupressure Therapy on Noise-Induced Tinnitus: A Retrospective Analysis

Objective: This retrospective analysis aimed to assess the effectiveness of auricular point acupressure therapy as an adjunct to conventional treatment for noise-induced tinnitus. Methods: The study retrospectively analyzed the data of patients with noise-induced tinnitus admitted to the Sandun branch of Zhejiang Hospital from June 2020 to June 2023 and included 100 patients for analysis. Based on the different treatments, the patients were divided into a conventional therapy group (methylcobalamin tablets for 4 weeks, n = 52) and an auricular point acupressure therapy group (methylcobalamin tablets and auricular point acupressure therapy for 4 weeks, n = 48). The baseline characteristics, tinnitus loudness, hearing thresholds, Tinnitus Handicap Inventory (THI), Tinnitus Evaluation Questionnaire (TEQ), and clinical efficacy were assessed before and after treatment. Results: After 4 weeks of treatment, compared with the patients in the conventional therapy group, those in the auricular point acupressure therapy group had an advantage in tinnitus loudness, hearing thresholds, and THI and TEQ scores, and the differences were statistically significant (P < 0.05). The clinical effectiveness in the auricular point acupressure therapy group was significantly higher than that in the conventional therapy group (P < 0.05). Conclusion: Auricular point acupressure therapy has a substantial effect on the treatment of noise-induced tinnitus. It is superior to conventional therapy in reducing tinnitus loudness and hearing thresholds. As a noninvasive therapy, auricular point acupressure has the potential to be an adjuvant therapy for noise-induced tinnitus.
