Abstract
• Nasal mucociliary function is one of the most important and indispensable mechanisms of the respiratory tract, providing protection against the atmospheric environment. We previously found mucociliary dysfunction in the noses of adult patients suffering from chronic sinusitis. In this study, using the saccharin method, we determined nasal mucociliary function in normal children and in children with chronic sinusitis. The mean (±SD) value of saccharin transit time in the nose was 28.2±19.9 minutes in patients with chronic sinusitis, this being significantly slower than that in the control group of children. The incidence of abnormally slow nasal mucociliary transport time (>30 minutes) in patients was significantly higher than in controls of the same age. Mucociliary dysfunction may initiate a vicious cycle of self-mediated inflammation and may be important in recovery from chronic respiratory inflammation.
