Objective: The study aims to ascertain the prevalence of paranasal sinus variations among healthy adults in Turkish population, as well analyze symmetry these variations. Methods: CTIs 200 adult patients who did not have any trauma, carcinoma, tumor, surgery, or a condition that could affect anatomy, such chronic rhinosinusitis, were included. prevalences Agger nasi cell (ANC), supraorbital ethmoid (SOEC), Haller's (HC), middle turbinate pneumatization, and frontal (FS) agenesis population revealed. Results: Bilateral SOECs found 38.5% patients, at least 53% had on one side. In 21.5% instances, LCs observed both sides; 35% they ANCs bilaterally 68.5% total, rate with ANC side was 84.5%. bilaterality Haller (HC) 24%, it 43% cases. concha bullosa (CB) 19% while CB variation 42%. absence FS be 8.5%, unilateral 2.5%. Conclusion: most common ANC, agenesis. inheritance prevalent SOEC. findings our hold significance for interventional procedures involving region.
