Allergic Laryngitis and Pollinosis from Japanese Cedar Pollen

Abstract

The clinical symptoms of allergic laryngitis are persistent paroxymal cough, itching, pain and irritation of the throat. The etiology of this disease might be an allergic reaction and hypersensitivity of the sensory nerve system in the mucosa of the pharynx, larynx and trachea. 76% of our patients with Japanese cedar pollinosis had some kind of laryngeal symptoms. The lower respiratory tract in these patients showed a methacoline hypersensitivity of approximately 70%.
