title: [Clinical study of the paranasal sinuses of patients with Japanese Cedar pollinosis].
abstract: To clarify paranasal sinus change in patients with Japanese cedar pollinosis, we studied reactions to medical treatment via X-ray images of patients during the 2000 cedar pollen season. Medication was administered to 577 patients consulting facilities in 3 regions--Kyoto, Fukui and Osaka--having different pollen counts i.e., 4555/cm2 in Fukui, 801/cm2 in Kyoto and 531/cm2 in Osaka. The paranasal sinus was X-rayed by Water's method, and the degree of positivity was classified by Katagiri'shadow classification. Patients were grouped into 334 suffering extensive Fukui pollen dispersion and 243 suffering relatively limited Kyoto and Osaka pollen dispersion. At 3-4 weeks after pollen dispersion, contrast shadow positivity was 22.2%, with no difference before pollen dispersion (22.2%) in Kyoto and Osaka. In Fukui, positivity was 39.7%, a clear increase over pre pollen dispersion (19.2%). In the initial treatment group, positivity was 25.8% in Fukui and 28.6% in Kyoto and Osaka. Our results suggest that the incidence of sinusitis in patients with Japanese cedar pollinosis tended to increase with exposure to extensive pollen dispersion and to be suppressed by initial treatment.
