Prevalence of the paranasal sinuses among the patients.
After assessing the CT scans, the data showed that the most frequently affected were maxillary sinuses, with a total (31.7%, n = 586) of all positive cases. unilateral maxillary antrum sinusitis was the most frequent pathologies (20.49%, n = 249) of all positive findings, maxillary polyps (Fig 3).

Patients brain CT scans show the incidental detection of paranasal sinuses abnormalities; (A) right maxillary antrum polyp, (B) bilateral maxillary polyp with retention cyst, (C) maxillary antrum polyp and right nasal air fluid level likely abscess, (D) right frontal sinusitis, (E) normal paranasal study, (F) right maxillary antrum mucosal thickening.

Shows the frequencies and percentage of the sociodemographic data as well as the pathological findings of the positive cases.
Table 2.
Shows an association between gender and the types of paranasal sinusitis.
It represents the frequency (%), and yes/no indicates the presence/absence of the abnormality. For the positive findings section, the patient was considered positive if he/she expressed one or more abnormalities.
