Objective: The objective of the present study was to record the prevalence of incidental maxillary sinus pathologies in patients using cone beam computed tomography (CBCT) scans performed for maxillofacial diagnostic purposes. Methods: This study was carried out retrospectively on CBCT records from January 2017 to July 2019. Pathologic findings were categorized as mucosal thickening, opacification, polypoidal mucosal thickening, others (such as antrolith, septa, or discontinuity of the sinus floor), and no pathologic findings. The incidence of maxillary sinus changes and their correlation with age and gender was analyzed. Results: A total of 683 scans were identified out of which 252 cases met the inclusion criteria. Pathologies were similar across age groups with a slight male predilection. The incidence of maxillary sinus pathologies overall was 68.2%. Both sinuses showed changes in 39% cases, and 29% cases had unilateral findings while 32% cases had no sinus abnormalities. Mucosal thickening, opacification, and polyps were higher in males on both left and right sides. Females showed an increase in incidence in other findings such as antroliths, septa, and discontinuity of the sinus floor more on the right side. The results were not statistically significant. Conclusion: Incidental maxillary sinus abnormalities are highly prevalent in asymptomatic dental patients. Oral radiologists should be aware of these incidental findings and comprehensively evaluate the entire captured CBCT volume, which can help in early diagnosis, treatment, and follow-up of the patient.
