In this study, the material was collected through the patient who visited the Dept. of Otolaryngology, S.N.U.H. for rhinologic problems. The total number of the patient was 102. The patients filled out the questionare first, and a careful search was made for intranasal pathology, especially nasal discharge and middle turbinate change. Two X-ray films were taken with patient sitting. They were Water's view and Caldwell's view. The intranasal findings and the X-ray finding were classified as to severity. Following results were obtained. 1) X-ray shadow was more evident in cases with purulent nasal discharge than cases with mucoid discharge, especially in Water's view. 2) In cases with middle turbinate change and radiologic abnormalities on X-ray films, the degree of the X-ray change was proportional to the degree of the edematous change, hypertrophic change and polypoid change. This phenomenon was more prominent in ethmoid sinus. 3) In cases with normal intranasal findings, normal X-ray findings were observed in 67.9% and the radiologic findings suggesting subclinical sinusitis were observed in 35.1%. Definite findings were found in 10.8% of the cases. 4) When there was no discharge or when the discharge was watery or mucoid, the change of middle turbinates were not evident, but the change of the middle turbinate was marked in the cases with purulent discharge. 5) Chief complaints of chronic maxillary sinusitis were headache (64.9%), nasal stuffiness (55.4%) and rhinorrhea (47.3%) in order. 6) The early edematous change of middle turbinate in sinusitis progressed into the stage of hypertrophy and polypoid change, associated with the duration of the disease.
