[The functional status of the upper respiratory tract in the long-term smokers].

The objective of the present study was to evaluate the functional status of the upper respiratory tract in 50 long-term smokers based on the results of comprehensive medical examination, determination of mucociliary transport time, endoscopic study of the oral cavity and nasopharynx, anterior active rhinomanometry, computed tomography of the nasal cavity and paranasal sinuses, fibroendoscopic study of the larynx, and stroboscopy. It was shown that the most significant changes in the nasal cavity were associated with various forms of chronic rhinitis whereas chronic catarrh and hyperplastic laryngitis caused the most pronounced changes in the larynx.
