Impact of Allergic Rhinitis on Nasal Mucociliary Clearance Time in Children.

Background: Mucociliary clearance is one of the most important protective functions of the airway. Previous studies, checking the influence of allergic rhinitis (AR) on mucociliary clearance time (MCT), were made on small patient groups and brought contradictive results.

Objectives: The aim of the study is to confirm whether AR in children influences MCT.
