A Comparative Study of Radiographic Images of Maxillary Sinusitis

상악동염에 관한 방사선학적 비교 연구

The purpose of this study was to evaluate the Waters' views, panoramic and periapical radiograms as well as clinical symptoms in the diagnosis of maxillary sinusitis. The author analyzed the types of mucosal thickenings, the types of bony wall changes, the pathologic changes of antral floors and total amount of agreement on radiograms in 495 patients with 505 maxillary sinuses which demonstrated radiographic changes. The results were obtained as follows : 1. 125 cases (24.8％) showed the mucosal thickening of antral floor and lateral wall (Type II), 106 cases (20.9％) showed the mucosal thickening around the whole antral wall (Type N) and 75 cases (14.8％) showed increased radiopacity of whole antrum. 2. Among 505 cases of mucosal thickenings, 319 cases<63.2％) showed the bony wall changes: 114 cases (35.9％) showed the thinning of lateral walls, 105 cases (32.8％) showed the thickening of lateral walls and 47 cases(14.7％) showed indistinct antral walls. 3. Among 6 types of mucosal thickenings, the incidence of bony wall changes was high in type VI(73.3％) and in type IV(71.6％). 4. 139 cases(25.1％) showed no pathologic change of antral floor, 127 cases(22.9％) showed the indistinct antral floor and 122 cases (22.1％) showed the halo appearance of antral floor on panoramic and periapical radiograms. 5. 449 cases (88.9％) showed apparent increased radiopacity and 47 cases(9.3％) showed suspicious increased radiopacity on Waters' views. 280 cases (71.6％) showed apparent increased radiopacity and 88 cases (22.5％) showed suspicious increased radiopacity on panoramic radiograms. And 141 cases (31.6％) showed apparent increased radiopacity and 133 cases(33.4％) showed suspicious increased radiopacity on periapical radiograms.
