TRANSITION OF CLINICAL PICTURE OF CHRONIC PARANASAL SINUSITIS

Abstract

In order to clarify transition of the clinical picture of chronic sinusitis intranasal findings at the first consultation were recorded periodically at Nagoya City University Hospital from 1959 to 1972 and the following results were obtained.
1. The percentage of cases with chronic paranasal sinusitis among all the outpatients decreased slightly since 1968. But no change was observed in the absolute number of such patients.
2. Clinical findings and X-ray examinations showed the disease become somewhat milder in nature since 1966.
3. It appeares that the incidence of purulent type of this disease decreased since 1962 as seen from the fact that the frequency of purulent discharge showed an evident decline among these patients.
4. The incidence of polyp formation in the middle nasal meatus tended to decrease slightly since 1962 but it still is found in about 20% of the patients.
