Morphometric assessment of sphenoid sinus ostium by cone-beam computed tomography: A retrospective study

Objective: The aim of this study was to evaluate the sizes of the sphenoid sinuses ostia, the distance between them, and the distance between the lateral margin of the sphenoid sinuses ostia and the anterolateral wall of the sinuses in the Turkish population. Methods: The analysis was performed as a retrospective study of 240 cone-beam computed tomography scans of patients using NNT Viewer software program (CeflaGroup, Verona, Italy). Patients over 18 years old with no pathologies present in the sphenoid sinuses were included in the study. Patients who had suffered from head trauma or undergone nasal, orbital, or cranial basis surgery were excluded from the study. Results: The mean size of both sphenoid sinuses ostia was 2.18 ± 0.42 mm for females and 2.26 ±0.53 mm for males. The mean distance between both sphenoid sinuses ostia was 6.19 ± 2.10 mm for females and 6.87 ± 2.10 mm for males. The mean distance between the lateral margin of the sphenoid sinuses ostia and the anterolateral wall of the sinuses was 9.66 ± 2.06 mm for females and 10.61 ± 1.95 mm for males. There was no statistically significant difference between the right and left ostium sizes of males and females. Right ostium diameters of cases over 45 years of age were statistically significantly higher than those under 45 years of age. Conclusion: Intraoperative identification of sphenoid sinus ostium is difficult, and its inadequate excision could lead to potential iatrogenic complications. Therefore, detailed morphometric measurements in populations are needed to perform safe and effective procedures. Keywords: Anatomy, CBCT, morphometric, sphenoid sinus, spheonid sinus ostium
