Objective: to estimate the incidence of teacher dysphonic disease in order to subsequently delineate prevention programs. Methods: a representative sample of teachers from different institutes in Catania, i.e. nursery, elementary, secondary and high school, were admitted to a test program.
Results: The analysed cards were 379. 46% of teachers frequently showed an alteration of the characters of the voice, 43% rarely showed it while only 11% did not show such alteration. The dysphonic disease was present in teachers that reported one or more of following pathologies: allergies, gastric disturb and thyroid pathologies. On the contrary this disease was not present in those who were not suffering from such a pathologies. 24% of teachers have reported to have been absent from school because of dysphonia. Conclusions: this study puts in evidence that teacher vocal sickness is only partially referable to the specific professional activity, but it is largely due to a psycho-physics predisposition. More studies are however necessary in order to specify the role of working and extra working factors in this group of voice practitioners.
