A consecutive series of 107 patients with dysosmia in the Department of Otolaryngology, Mie University Hospital during the four years from 1974 to 1977 was studied clinically. The pernasal olfaction test with exponentially diluted odors of five kinds (beta-phenyl ethyl alcohol, cyclotene, iso-valeric acid, gamma-undecalactone and scatol), which had been standardized by the task group for olfaction in Japan, was employed for evaluating the olfactory acuity of the patients. Of the 107 patients, 76 were anosmic, 23 were hyposmic and 8 were parosmic. Pathogenesis of dysosmia were analysed by the patient's history and symptoms, rhinoscopic and radiographic findings of the nose and the intravenous olfaction test, and could be classified into the four groups of respiratory disturbance (R), peripheral nerve disturbance (P), combination of respiratory disturbance and peripheral nerve disturbance (R+P) and central nervous disturbance (C). There were 20 patients with R, 14 with P, 53 with R+P and 20 with C. For patients with R or R+P, therapy with nasal drops containing steroid solution was conducted while the patient was lying supine with the head bent far backward. By this treatment, 85% of the patients with R and 75.5% of those with R+P were improved. However, there were no efficacious therapies for patients with C or P.
