Introduction: Voice disorders primarily affect workers in professions with increased voice demands, such as teaching personnel in educational system, singers, lecturers, actors or managers. Severe voice disorders often require a permanent change of work position. Methods: Retrospective analysis of a set of patients with occupational voice disorders who were hospitalized at the Clinic of Occupational Medicine and Toxicology, Martin University Hospital (COMaT, MUH) in the years of 2000–2017. Comparison of the data obtained with the National Centre of Medical Information (NCMI) data on the occurrence of occupational voice disorders throughout the Slovak Republic (SR). Comparison with the retrospective analysis of reported occupational voice disorders in the years of 1967-1996. Case report of a patient with an occupational voice disorder. Results: We point to a long-term low incidence of occupational voice disorders. In the years of 2000-2017, 24 cases of occupational voice disorders were reported in Slovakia, of which 20 cases were reported under item 42-1 and 4 cases under item 42-2 in the List of Occupational Diseases. Through the COMaT, MUH 11 cases of occupational voice disorders were reported during these years, of which 9 cases were listed under item 42-1 and 2 cases under item 42-2. From 1967 to 1996 there were 52 occupational voice disorders reported in Slovakia, of which 45 were under item 42-1 and 7 under item 42-2. Conclusions: As there is a tendency to underestimate the voice difficulties among teaching staff, it is necessary to provide better information about the possible consequences, prevention, and treatment of these diseases. All of this should be in the competency of occupational health services.
