The purpose of this study is to figure out the prevalence and the identification of factors that are associated with dysfonia among 236 teachers from Public Schools in Criciúma-SC. The teachers answered a questionnaire about the characteristics of their work place, their vocal habits, self perception of dysphonia, search for professional help, the use of medicine, and about their voice care. The teachers who mentioned three or more vocal symptoms went through a vocal screening. After being screened, the teachers were sent to an otolaryngological evaluation. A chi-square test was made in order to detect association among independent variables and dysphonia. The result showed a range between 17,15% (considering lost of follow-up as non dysphonia) to 46,80% (considering lost of follow-up as dysphonia) of dysphonia prevalence among teachers. The associated factors for dysphonia were the habit of speaking too much, the amount of information on voice good practices, search for expertise help and being an ex- smoker. This study also aimed at pointing at the importance of preventive actions that could be taken with governmental support to prevent this kind of health problems.
