Aims The current study was performed to find out an easiest fixed bony landmark on computerized tomographic scans for localizing the sphenoid sinus ostium before embarking on to the FESS and Pituitary Surgery. Methods It was a retrospective study in which computerized tomographic (CT) scan axial cut of sinuses from 166 patients were reviewed to determine average distance between Posterior Maxillary Wall (PMW) and the Front of Sphenoid (FOS) in both right and left sides. Results Mean age of the patients was 41.18±14.75 (95 per cent CI=38.92–43.44) years. Males (n=88, 53.01 per cent) and females (n=78, lcsh:R5-920, 46.99 per cent) were almost equally participated in the study. The average anterior-posterior distance from the PMW to the FOS was on the right side 7.1mm and on the left side 7.9mm, medicine.diagnostic_test, business.industry, Key Words Sphenoid sinus, General Medicine, Anatomy, pituitary surgery, Ostium, medicine.anatomical_structure, minimally invasive, lcsh:Medicine (General), business, 030217 neurology & neurosurgery
