We studied the efficacy of nasal irrigation on the symptoms of Japanese cedar pollinosis, in 15 patients consulting the ENT Department at Dokkyo University School of Medicine Koshigaya Hospital from 2001 to 2002.
All kept a nasal symptom score on untreated sneezing, rhinorrhea, and nasal obstruction in 2001, resulting in 8 serious, 5 moderate and 2 mild cases.
Eight-5 serious, 2 moderate, and 1 mild-of the 15 patients underwent nightly nasal irrigation with 150cc of warm water (40°C) containing Azunol (2g) from the mid of February to the last day of March, while the remaining-3 serious, 3 moderate, and 1 mild-kept untreated nasal symptom score as a control group.
Although the significant effect of treatment for all idividual symptoms was not shown, rhinorrhea and total symptom scores improved significantly (p<0.05), suggesting that nasal irrigation was effective in treating the symptoms of Japanese cedar pollinosis.
