Morphometric evaluation of Sella Turcica on cone beam computerized tomographic images

Sella turcica is an important anatomical formation that contains glandula pituitaria in corpus ossis sphenoidale. Sella turcica was given this name, which means 'Turkish saddle' because it is similar to the saddle the Turks invented. It is important to know the morphometry and morphology of sella turcica as it has many vital structures around it and it is a transit point during the surgical interventions to this area. The aim of this study is to contribute to literature by determining morphometric reference values of bone structures belonging to sella turcica in Cone Beam Computed Tomography (CBCT) images of individuals living in Anatolia who do not have pathology in the sellar region between the ages of 18-65. For this purpose, CBCT images of 400 individuals, 200 women and 200 men, were evaluated retrospectively. A total of 8 parameters were examined, 6 in sagittal section and 2 in transverse section and sella turcica morphology was evaluated in two different categories. In the sagittal plane; length of sella turcica 10.19±1.77 mm, diameter of sella turcica 11.6±1.69 mm, anterior height of sella turcica 7.88±1.56 mm, media height of sella turcica 8.18±1.42 mm, posterior height of sella turcica 6.98±1.31 mm, width of sella turcica was determined as 11.10 ± 1.6 mm. In the transverse plane distance of processus clinoideus anteriors 24.93 ± 2.57 mm, distance of processus clinoideus posterior was 14.92 ± 2.46 mm. The most common form in sella turcica morphologies was 'normal sella turcica' (59%) and in another category, 'circular' (48.75%). It is thought findings will contribute to the literature in the study of sella turcica and surrounding structures.
