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