Abstract
Objective: The aim of our work was to study the prevalence of maxillary sinus abnormalities in asymptomatic Saudi adult population using computed tomography. Materials and methods: It was retrospective study in King Khalid Hospital in Al-Kharj. It was designed to evaluate all patients who underwent brain CT scanning for any reason unrelated to maxillary sinuses abnormalities. 1442 patients underwent CT scans in past ten months from July 2020 to early May 2021 and evaluated by two examiners for identification of any abnormalities. All demographic data and radiological features related to maxillary sinuses were evaluated. Results: Retrospective CT scan analysis for incidental maxillary sinuses abnormalities revealed that about 495(34.33%) of the cases had positive findings, where the majority were males 517 (67.1% of the positive findings) while the females represented around 254 (32.9% of the positive findings). Of all these findings, the most frequently maxillary sinuses pathology found was Mucosal thickening 575 (39.88%) of all cases. Conclusions: Spread of incidental maxillary sinus abnormalities is more in the asymptomatic patients.
