Ventilation of the paranasal sinuses is critical in curing rhinosinusitis, because blockage of the natural ostium leads to retention of nasal discharge or pus. In a previous study, we studied the effect of widening the middle nasal meatus in patients with rhinosinusitis. Patients were assigned to two groupes. X-ray densities were significantly better in the meatus-treated group than those in the non treated group.In this study, we focused on efficacy in the same patient. Cotton wool soaked with epinephrine was applied to widen the middle nasal meatus for 10 minutes after cleaning it (widening treatment) . Widening treatment was used on one side, but not on the other. Other conditions such as nebulizer and taking macrolides were the same. We quantified improvement in paranasal sinuses by densitometric X-ray analysis. The improvement ratio was significantly better on the treated than on the non treated side (p<0.05). We verified the efficacy of widening by both interindividual reseach in the past and intraindividual treatment in this study.
