Morphometric Analysis of Sella Turcica Using Cone Beam Computed Tomography

Abstract

The anatomical structure of sella turcica can be studied effectively in CBCT images. Linear dimensions and shape of sella turcica in the current study can be used as reference standards for further investigations.

Morphometric analysis of the sella turcica in Turkish individuals with different dentofacial skeletal patterns

“…In this study, no significant differences were found between genders in respect to the size of sella turcica, except for the diameter, which is in accordance with the literature [4,20,32,35,44]. Females had a greater diameter size of sella turcica than males (p<0.01) ( Table 4).…”

“…Therefore, knowing about the relation betweenthe sella turcica shape and size and the dentofacial skeletal types can be beneficial for providing an accurate decision for the management plan. Moreover, morphometric information about the sella turcica is essential for neurosurgeons to choose the most suitable surgical procedure to prevent damage to structures in relation to the pituitary [44].…”

Sella turcica variations in lateral cephalometric radiographs and their association with malocclusions

“…An enlarged sella turcica may also be observed in empty sella syndrome, where the herniation of the subarachnoid space with cerebrospinal fluid occurs. [6,10,19] Yasa et al [4] used cone beam computed tomography to examine the sella turcica morphology. Using a different classification system, they found that 69.5% of the cases had a circular morphology, 16.4% were flat, and 14% were oval in shape.…”

“…[1][2][3][4][5][6] Development of sella turcica is closely associated with the development of the hypophysis. The size of the sella turcica will vary depending on the normal or pathological development of the hypophysis, [3,4] which is the primary endocrine gland controlling most of the endocrine functions. 25% of the anomalies diagnosed in the lateral cephalometric radiograms by the orthodontists account for the glandular anomalies.…”

“…[2,7] Besides its importance endocrinologically, the hypophysis is also important due to its anatomical location, including its proximity to the hypothalamus, optic chiasm, sphenoid sinus, cavernous sinus and its internal anatomic structures. [4,5] The recent developments in endoscopy allowed transnasal endoscopic approaches performed in the sellar region and its surroundings. The anatomical structures, especially the shape of the posterior clinoid processes, are of importance during this process.…”
