Radiological Study of the Sinuses of Patients with Japanese Cedar Pollen Allergy

Abstract

We examined 131 patients with Japanese cedar pollinosis in our hospital from 1986 to 1989. Paranasal sinusitis was found by x-ray in 30%. The incidence of sinusitis in these patients tended to increase with the duration of exposure to the pollen. The results suggest that sinusitis in patients with Japanese cedar pollinosis is a reversible disorder caused by exposure to the pollen.
