Efficacy of tinnitus retraining therapy in the treatment of tinnitus: A meta-analysis and systematic review.

Abstract

PURPOSE\nTo evaluate the efficacy of Tinnitus Retraining Therapy (TRT) in the treatment of tinnitus.\n\n\nMATERIALS AND METHOD\nComputer retrieval of PubMed, Embase, The Cochrane Library, Web of Science, China National Knowledge Internet (CNKI), Wanfang data, etc., were conducted. According to the inclusion and exclusion criteria, the literature s quality was evaluated, and useful data was extracted. All statistical analyses were performed by RevMan5.3 software.\n\n\nRESULTS\n13 eligible RCTs with a total of 1345 patients were included in this meta-analysis. The meta-analysis results showed that the 1-month response rate, 3-month response rate, 6-month response rate, and overall response rate of TRT with drugs for tinnitus were higher than that of drugs only (P\xa0<\xa00.05). The results demonstrated that the THI scale after the treatment period of TRT with medications for tinnitus was lower than that of drugs only (P\xa0<\xa00.05).\n\n\nCONCLUSIONS\nAnalysis of limited studies low-quality evidence with a high risk of bias showed that the TRT was an effective treatment for tinnitus, which could improve the response rate of tinnitus and reduce the THI scale. However, more multicenter RCTs with a large sample number and high quality should verify the conclusion mentioned above.
