Background: Acupuncture is widely used in the treatment of tinnitus worldwide because of its good efficacy and safety. However, the criteria for selecting acupoint prescriptions and combinations have not been summarized. Therefore, data mining was used herein to determine the treatment principles and the most effective acupoint selection for the treatment of idiopathic tinnitus. Methods: The clinical research literature of acupuncture in the treatment of idiopathic tinnitus from the establishment of the database to September 1, 2023 in China National Knowledge Infrastructure, China Medical Journal Full-text Database, PubMed, Embase, Cochrane Library and Web of Science databases was retrieved and extracted. Microsoft Excel 2016 was used to establish the acupoint prescription database and the frequency statistics of acupoints, meridians and specific acupoints were carried out. IBM SPSS Statistics 25.0 software was used for cluster analysis of acupoints, and IBM SPSS Modeler18.0 software was used for association rule analysis of acupoints. Results: A total of 112 articles were included, involving 221 acupuncture prescriptions, including 99 acupoints, with a total frequency of 1786 times. The 5 most frequently used acupoints were Tinggong (SI19), Tinghui (GB2), Yifeng (TE17), Ermen (TE21), and Zhongzhu (TE3). The commonly used meridians were Sanjiao meridian of hand-shaoyang, Gallbladder meridian of foot-shaoyang and Small intestine meridian of hand-taiyang. The specific points are mostly Crossing point, Five-shu point and Yuan-primary point. The core acupoint combination of association rules was Ermen (TE21)–Tinggong (SI19)–Tinghui (GB2)–Yifeng (TE17), and 3 effective clustering groups were obtained by cluster analysis of high-frequency acupoints. Conclusion: In this study, the published literature on acupuncture treatment of idiopathic tinnitus was analyzed by data mining, and the relationship between acupoints was explored, which provided a more wise choice for clinical acupuncture treatment of idiopathic tinnitus.
