Abstract:
This study aims to analyze the morphological dimensions of sella turcica to determine if differences exist due to gender, age or in subjects with different skeletal patterns. Methods: A total of 100 (43 males and 57 females) sella turcica cephalometric radiograph was traced. Linear dimensions of sella turcica (length, depth, and diameter [in mm]) were measured and skeletal shape/type (normal, bridging, double contour, oblique, irregular, and pyramidal) was assessed. A Student’s t-test was used to calculate the mean differences in linear dimensions of sella turcica between males and females and between different age groups, skeletal types. A Chi-square test was used to test the interrelationship of gender, age and skeletal types with the shape of sella turcica. Results: In low angle group subjects, 80% of the subjects had normal sella and 20% of the subjects had variations in morphology and in high angle group subjects, 76% of the subjects had a normal sella, and 24% of the subjects had variations in the morphology. Conclusions: The shape of the sella turcica was normal in 78% of the subjects, and there was a significant difference in length between high and low angle subjects, where the length of sella was larger in the low angle subjects and the distribution of shape of sella turcica was found to be significantly different among both high and low angle types.
