Morphometric analysis of sella turcica in North Indian population: a radiological study

Abstract

Background: The purpose of this study was to describe the morphology and measure the size of the sella turcica in North Indian population. Methods: Lateral cephalometric radiographs of 180 individuals (90 males and 90 females) with an age range of 12-65 years were taken. Morphology of sella turcica was studied and various measurements were taken to determine the shape of the sella. Statistical analysis was done to calculate differences in dimensions and to establish if any, relationship exists between age, sex and the morphometry of sella turcica. Results: The study found that sella turcica presented with a normal morphology in only 28 per cent of the subjects. A significant difference in linear dimensions between genders was found in sella height and width. When age was evaluated, some dimensions showed negative correlation with the age. Sella size of the older age group was as a rule larger than the younger age. Conclusion: Pathological enlargement of the pituitary fossa can be detected by this technique and may also be helpful in providing data in the assessment of racial, gender, age specific variation in the skull.

Morphometric assessment of sella turcica using CT scan

“…[4,19] We, therefore, believe that our CT study provides more accurate results than other studies that typically use cephalometric radiography.…”

“…In the study by Najim and Al-Nakib, [13] a statistically significant difference was noted only in sella depth. Chauhan et al [4] reported that sella dimensions were larger in the higher age group compared to the lower age group. Similarly, Preston [18] determined a close correlation between sella area and age.…”

“…[1,4,5] Sella turcica is a bony structure that is closely related with the pituitary gland, and is of both anatomical and clinical importance. The sellar and parasellar regions are anatomically complex structures where neoplastic, infectious, inflammatory, developmental and vascular pathologies may develop.…”

“…It is enclosed by the pituitary fossa in which the pituitary gland is lodged, tuberculum sellae on the front and dorsum sellae in the rear. [1][2][3][4] Two anterior and two posterior clinoid processes form a protrusion on the pituitary fossa, and these are the structures that protect the pituitary gland in the sella turcica. The extensions of the sphenoid bone's ala minor to the anterior and medial form the anterior clinoid processes.…”

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

“…In the studying population, the prevalence of irregularity on the posterior part of the dorsum sellae was reported as 15%, and the bridging of sella turcica was reported as 8%. Unlike the others, Chauhan et al (2014) [13] noted that only 28% of the cases observed had anatomical variations. Anatomical variations included an oblique anterior wall (23%), irregular sella (18%), bridging (17%), and double contour floor (10%).…”
