Topic > Meaning of the sella turcica

The sella turcica is a saddle-shaped depression visible on the upper surface of the sphenoid bone and is located between the two anterior and two posterior clinoid processes. It is composed of three parts: the tuberculum sellae, the pituitary fossa consisting of the pituitary gland and the dorsum of the sella [1, 2]. The morphological appearance of the sella turcica is established in the initial embryonic structure. Variations in the shape of the sella urcica have long been reported by many researchers. The shape of the sella turcica was classified as circular, oval, and flattened or saucer-shaped, and the majority of subjects had a circular or oval sella. Other classifications were based on the contours of the floor of the sella, the angles formed by the contours of the anterior and posterior clinoid processes and the tuberculum sellae, and the fusion of both clinoid processes as the bridge of the sella turcica [3,4]. There are six main types of sella turcica as investigations: normal sella turcica, oblique anterior wall, double-profile sella, irregularity (notch) in the back of the sella, pyramidal shape of the sella dorsum, and sella turcica bridge. plagiarism.

Get an original essay Cases of larger sella turcica in the hyperfunctioning pituitary gland and smaller sella in the hypofunctioning pituitary gland have been reported in the literature. During embryonic development, the sella turcica area is the key point for the migration of neural crest cells to the frontonasal and maxillary developmental fields. The formation and development of the anterior pituitary gland, sella turcica, and teeth have in common the involvement of neural crest cells, and dental epithelial progenitor cells differentiate through sequential and reciprocal interaction with neural crest-derived mesenchyme . Based on this, it can be hypothesized that the pituitary gland acts as the functional matrix of the sella turcica. The development of the sella turcica is closely related to that of the pituitary gland, which must be completed before the sella turcica can form. A deviation in the development of the pituitary gland can lead to a deviation in the morphology of the sella turcica. Changes in the size of the sella turcica are related to any pathology of this region. Dimensional enlargement unaccompanied by bone erosion is usually found in intrasellar adenomas and empty sella syndrome. Other not-so-common causes, often enlargement, can include Rathke's cleft cysts and aneurysms. While in other diseases such as primary hypopituitarism, growth hormone deficiency and William syndrome, a small sella turcica may be observed. Forensic Significance: Forensic medical examination of unknown corpses is a complex identification process. The need for personal identification arises in cases of putrefaction, skeletonization and destruction of corpses when identification is complicated or impossible. Age, race, sex, portrait and other characteristics can be estimated by examination of the skull, teeth and post-cranial skeleton [12,13]. Skeletal remains do not change their characteristics over time and have sufficient information. However, the size of the sella turcica, and the smaller size of the sella turcica in particular, may cause pituitary dysfunction due to changes in the structure of the pituitary gland or may be associated with certain genetic or acquired endocrine disorders. In this study, 20 cephalometric radiographs each of males and females belonging to the 10-30 years category were analyzed to identify the morphological difference between individuals.
