Abstract
To determine the prevalence of incidental maxillary sinus findings and assess their relationships with age and gender. CBCT scans of 412 patients, comprising of 824 maxillary sinuses were evaluated. The maxillary sinuses were observed for increased mucosal thickening, polypoidal-mucosal thickening, opacification and other pathological changes. Correlations of these pathologic findings with age and gender were analyzed. The incidence of the pathological findings in maxillary sinuses observed was 30.1%. The most common abnormality observed as mucosal thickening followed by opacification. No significant correlation was observed between genders and different age groups. Based on the observations of the present study, it can be concluded that the prevalence of incidental maxillary sinus abnormalities in Saudi Arabian observed on CBCT is considerably high.
