IntroductionThe purpose was to determine the incidence of voice disorders in a group of professional actors and singers, to compare the two groups, and to investigate the potential causes of their voice problems.Methods65 actors and 63 singers from professional theatres and choirs were included. The data concerning voice problems, their possible causes, and factors adversely affecting voice quality were obtained through a questionnaire. The results were compared between the groups of professional singers and actors, and between the subgroups of singers and actors both with and without frequent voice problems.ResultsThe incidence of frequent voice problems over the entire career in singers and actors was lower than reported in the literature. Professional actors displayed more inappropriate life and vocal habits than the singers. Significant risk factors for voice disorders in singers turned out to be loud speech (p=0.029) and the presence of allergies or asthma (p=0.048). No such significant risk factors were found in actors.ConslusionThe study confirmed the importance of preventive examination of the vocal tract function before enrolling in studies for an elite voice user. Professional singers and especially actors demonstrated insufficient knowledge of proper voice care. The results suggest that elite voice users require additional information on voice hygiene and occasional professional help from college to the end of career. Speech and language therapists can play a crucial role in such voice care in order to effectively prevent voice problems in elite voice users.
