Efficacy of Treatment to Clean and Widen the Middle Nasal Meatus on Rhinosinusitis.

Ventilation of the paranasal sinuses has been hypothesized to be a critical factor in curing rhinosinusitis, because blockage of the ventilating sinuses can lead to retention of nasal discharge or pus. In this report, we investigated the effect of treatment to clean and widen the middle nasal meatus in outpatients with rhinosinusitis. The outpatients were assigned to two groups: in the first group, cotton wool soaked with epinephrine was applied to the middle nasal meatus for 10minutes after cleaning the meatus at each consultation; in the second group, noepinephrine was used but the other conditions were the same. The treatment results were analyzed using X-rays, and subjective complaints via a the questionnaire survey, and nasal symptoms and X-rays scores were significantly better in the first group compared to the second group (p<0. 0001, p<0.005).
