Introduction: Sella turcica is a saddle-shaped concavity located in the middle cranial fossa of the skull. The exact dimensions of sella turcica are an important consideration in the diagnosis, prognosis, and treatment of diseases related to the pituitary gland and brain. The sella turcica size and morphology is different from person to person. Thus, obtaining any data in this regard will be a great help in detecting abnormalities within this anatomic area. Aim: The objective of this study was to find out the correlation between the morphological variations of sella turcica with age and gender. Materials and Methods: Study sample consisted of 311 cephalograms of patients with age ranging 6–40 years. The contour of the sella turcica was traced and the linear measurements – length, depth, and diameter of sella turcica – were measured according to Silverman. Results: Morphology of sella turcica appeared to be normal shape in 27.3% of the study population followed by combination (26.7%), irregular (15.8%), pyramidal (10.6%), bridge (10%), oblique anterior wall (5.5%), and double contour (4.2%). Gender-wise comparison of the linear measurement was not statistically significant. Among the linear measurement, the parameter depth and diameter were statistically significant (P < 0.001) when correlated with age. On comparison of shape of sella turcica with linear measurements, the parameter length was statistically significant (P < 0.001). Conclusion: There is no significant relationship between the linear measurements and gender. There exists a significant relationship between the mean depth and mean diameter with age. That is, as age increases, the depth and diameter increase. There is a significant relationship between the length and the different shapes of sella turcica.
