Abstract
In the article, 20 scientific works were analyzed as sources, of which 6(30%) authors belong to the CIS countries, while the remaining 14(70%) belong to authors from abroad. The results of the analysis showed that the use of questionnaires that assess the quality of life (QOL) in the diagnosis of ENT diseases, including patients with chronic middle otitis, is of great help in improving the effectiveness of diagnosis and treatment. With COMQ-12 аnd COM-5 in different languages, it is possible to assess the course of the disease and its outcomes in different social and cultural settings around the world. This makes it possible to obtain a more complete and objective picture of the disease under investigation, and a tool for its evaluation. The high prevalence of CОМ, the serious complications of this pathology and the ambiguity of the surgical treatment approaches make it necessary to study this medical problem and find possible ways of optimizing the care of patients. The contradictions described by different authors in the evaluation of the results of the intervention are the consequence of the lack of a single tool for interpreting the obtained data and do not allow for a unified treatment approach.
