Abstract

In the present study, we investigated whether there is a relationship between sphenoid sinus (SS) types, septation (lobulation) and symmetry; and septal deviation (SD) by multidetector computed tomography (MDCT). Paranasal MDCT images of 202 subjects (131 males, 71 females), between 10- and 88-year-old, were included into the study. SS type (conchal, presellar or sellar), SS symmetry, SS septation (lobulation) and SD were evaluated by MDCT images. In the present study, in both males (83.2 %) and females (85.9 %); and in all age groups (80.4–85.7 %), sellar type sphenoid sinus were more detected. Conchal type was detected in two cases of the males (1.5 %) and none of the females. SS was detected mainly as multi-septated (multi-lobulated) (51.9 % in males and 56.3 % in females; in all age groups as 51.0–56.8 %; and both SD (+) and SD (−) groups as 51.2–56.8 %). In subjects with SD, asymmetric SS was detected in 80.2 %. Whereas in SD (−) subjects, asymmetric SS was detected in 50.6 %. Sellar type SS pneumatization is the most detected type in our cases. Presence of SD was related to the higher SS asymmetry values. In SD (−) subjects, SS was detected as symmetric. Nasal septal deformities such as SD may influence the development of the SS pneumatization and asymmetric septation. For well anatomic orientation of the surgeons, good anatomy knowledge and preoperative detailed examination of the CT scans are very important.
