Tinnitus compensation strategies based on the current neuroplasticity theories (systematic review)

Tinnitus is a serious medical and social problem of our time for many people, leading to significant psycho-emotional shock in some cases, disruption of social and professional adaptation. To date, there are several methods of treating tinnitus, the principle of which is based on pathogenetic concepts of brain neuroplasticity. The purpose of this work is to review existing tinnitus treatment methods from the point of view of modern neurophysiological concepts. Materials and methods: A keyword search and analysis of the works found in Russian and foreign databases (elibrary, CyberLeninka, PubMed, Scopus, Google Academic) over the past 5 years was carried out. A total of 387 keyword publications were found, and after eliminating duplicates and those that did not match the subject of the article, 21 papers were selected. Results. The use of non-medicinal tinnitus therapies such as sound therapy, transcranial magnetic stimulation, bimodal stimulation, and psychotherapeutic methods has shown statistically significant effectiveness in a number of systematic reviews and meta-analyses, both as part of monotherapy and as part of complex therapy aimed at retraining in tinnitus, which has shown the best results. The effectiveness of these methods has a neurophysiological explanation based on the neuroplasticity of the brain and the fact that changes occurring during the development of tinnitus can regress with certain measures. Thus, these options can be considered effective pathogenetic methods of treating tinnitus from the point of view of the principles of evidence-based medicine.
