[Rhinolaryngological functional diagnosis in exposure to irritants]

2,601 workers with exposure to irritant noxae received a standard occupational rhinolaryngeal check up supplemented with higher specialized methods. The measurements of mucociliary clearance, the screening--olfacto-/gustometry, the cytological investigations of the nasal mucous membranes with the smear technique, and the sonography of paranasal sinuses, too, were qualified for occupational practice. The significance of leading symptoms and the unity of upper and lower respiratory tract are to emphasize.
