[Analysis of voice diseases in patients treated in the Podlaski region].

Analysis of professional dysphonia in 309 patients treated in Phoniatric Outpatient Clinic of the (chair and) Department of Otolaryngology AM in Bialystok was performed. The teachers of primary and lower secondary schools were the majority of the patients. The teachers were compared with the 65 patients of other occupations. Additional harmful factors were excluded in both groups. In all patients' otolaryngologic, phoniatric and videostroboscopic examinations were completed. The analysis paid attention to functional and organic dysphonias. In the group of voice workers there were found early functional laryngeal disorders, which were progressive with the period of work. In other patients organic disorders were more common and occurred earlier than functional ones. The degree of dysphonia depended on laryngeal pathology, especially in case of functional dysphonia.
