We aimed to determine the position and size of the sphenoid sinus (SS) in our study and compare the results of the measurements relative to age, gender, and the presence of pituitary adenoma using multidetector computerized tomography (MDCT).


We retrospectively evaluated the paranasal sinus computerized tomography (CT) images of 200 individuals (age range of all the individuals 4–84 years; 101 females, 99 males; age range of individuals with pituitary adenoma 15–63 years; 15 females, 9 males) with 24 pituitary adenomas. The shape of SS were identified and classified, volume were measured by MDCT also for individuals with pituitary adenoma.


It was determined that the volume averages were significantly affected by the type of SS. Among all the individuals studied, the sellar type of SS was most frequently observed (41.5%), followed by the postsellar type (38.5%), and the least observed was the presellar type (9%). The volume of the SS is bigger in males than females although the volume is not affected by the presence of pituitary adenomas. The development of the SS continues until the age of nine.


The morphology and morphometry of the SS show individual differences. These anatomic variations are important for decision making and application for surgical interventions (especially transsphenoidal surgery).
