The size and morphology of sella turcica: A lateral cephalometric study

Abstract

Background: Sella turcica is a saddle-shaped concavity in the body of sphenoid bone situated in the middle cranial fossa of skull, clearly seen on lateral cephalometric radiograph. Aim: The purpose of the study was to measure the size and describe the morphology of sella turcica in different age groups and gender. Materials and Methods: Lateral cephalometric radiographs of 200 subjects of which 100 males and 100 females in the age group of 8-30 years were included in the study population. Linear dimensions which include the length, depth, and anteroposterior diameter were measured and the shape of sella turcica was analyzed and skeletal class of malocclusion was noted. Chi-square test and ANOVA test were used for statistical analysis. Results: In the present study, morphology of sella turcica appeared to be normal shape (upper contour of anterior wall of sella turcica appears to be perpendicular to floor) in 46.5% of the study population and morphological variations in shape were seen in 53.5% of study population. Whereas size was considered there was statistically significant increase in the depth and anteroposterior diameter of sella turcica as age advanced. There was no significant difference in the linear measurements of sella turcica between males and females. Conclusion: The most common shape of sella turcica in the study population was normal shape. There is a gradual increase in the size of sella turcica as age advances.

Morphometric assessment of sella turcica using CT scan

“…Similarly, Preston [18] determined a close correlation between sella area and age. Nagaraj et al [16] described increasing sella depth and AP diameter with increasing age. Hasan et al [14] reported that sella turcica dimensions differed significantly between age groups.…”

“…When Hasan et al [14] compared the dimensions of the sella turcica by gender and found no relevant differences between males and females, expect in sella height anterior. Ashraf et al, [1] Shah et al, [8] Najim and Al-Nakib, [13] Olubunmi et al [15] and Nagaraj et al [16] reported that sella morphometry did not differ between males and females. Silverman [17] found differences in the size of sella between genders in the preadulthood period, but no difference between males and Table 2 Comparison of sella turcica morphometry according to the decades.…”

3DCT Morphometric Analysis of Sella Turcica in Iraqi Population

“…There was difference in the linear measurements of depth, and anteroposterior diameter in each age group which increased as age increased and the difference was statistically significant with P < 0.05. Choi et al also reported that lin-ear dimensions of sella turcica had positive inclination with the age 24) . Based on the results of this study, gender differences were statistically insignificant for all linear and area measurements of sella turcica.…”
