Examination of 3D sella turcica models in three species of ruminants

Abstract

AbstractSella turcica is an important anatomical structure that contains the pituitary gland. Changes observed on the sella turcica facilitate the identification of diseases such as Down syndrome, Seckel syndrome and tuberculum sellae meningioma in humans. Therefore, studies in this region are critical for a better understanding of sella turcica. The crania of six adult male tuj sheep, five adult male hair goats and five adult male gazelles were used in the study. Cross‐sectional images of the cranium were captured using computed tomography. Cross‐sectional images were used to model the sella turcica region in 3D, and the region was analysed morphologically and morphometrically. It was observed in the study that fossa hypophysialis, dorsum sella and processus clinoideus caudalis were clearly observed on the sella turcica. The processus clinoideus caudalis in some animals was not split into two. In morphometric analysis, the sella turcica length and sella turcica height (rostral border) parameters were statistically significant between the groups (p < 0.05). Consequently, this study morphological and morphometric examinations were carried out on the sella turcica of different ruminant species, and the differences between the groups were discussed. This study is expected to contribute to the very limited number of related studies, taxonomy and clinical studies in this field.
