This study represents the morphology and measures the size and shape of the sella turcica in Bangladeshi populace and contrast with accessible global information. A sum of 166 (108men and 58 ladies) Bangladeshi subjects who went through Computed tomography (CT) scan at the Radiology Department were taken. A 3D imaging software (Mimics 11.02 Materialise) was utilized to process the CT images. Morphometric strategies were utilized to evaluate size and shape. The parameters for conventional measurements were three dissimilar sella height (anterior, posterior and median), sella length, diameter and width, where all of them deliberated in relation with Frankfort reference line (FH). Total area of sella turcica also considered. No important contrasts in size of the sella were found between sexes. The study found that sella turcica gave three unique shapes which were considered flat (28.3%), ovoid (48.1%) and circle (23.4%). In another morphological classification sella turcica represent 6 different variations. Those were normal sella (69.2%), oblique anterior wall (4.8%), double contour of sella floor (6.6%), sella turcica bridge (0 %), irregularity (notching) in the posterior part of the dorsum sella (16.2%) and pyramidal shape of dorsum sella (3.0%). Sella shape and measurements reported in the present study can be useful in giving reference information in the orthodontic determination, appraisal and treatment arrangement and evaluation of sex dimorphism in Bangladeshi subjects.
