The author evaluated the curative effect of nasal irrigation given collectively to school children with chronic sinus infection. Seventy-five affected children were treated by the nasal irrigation with saline solution for 3 months. At the end of the 3. months' treatment, the findings in the treated group were considerably improved compared with the contrast group, without treatment the difference being significant statistically. However, this difference in the findings in the nose between the two groups disappeared soon after the cessation of the treatment, revealing the fact that the curative effect of the nasal irrigation in chronic sinusitis was no more than a symptomatic.
