[Rhinitis medicamentosa in cytological assessment of the nasal mucosa].

Long term use of topical vasoconstrictors for the nose may result in rhinitis medicamentosa, the rebound swelling of the nasal mucosa. Usually discovery of any underlying reason for decongestant use is impossible, therefore treatment could be problematic. The aim of this study was to establish the nasal mucosal cytology of patients with rhinitis medicamentosa and evaluation of usefulness of exfoliative cytology in diagnostics of underlying reason of nasal decongestants overuse.
