ABSTRACT
One of the most commonly used cranial landmarks for cephalometric tracing is sella point. The morphology and size of sella turcica is of importance because within its center lies sella point which helps in evaluation of craniofacial morphology. The objective of this study was to measure and describe the size and shape of the sella turcica and find a correlation between males and females and the three different skeletal classes. Lateral cephalometric radiographs of a total of 180 patients above age 15 years were divided equally into class I, IIand III [60 patients in each group] and with equal representation of both genders [90 males and 90 females]. The sella turcica was carefully analyzed and measured in linear dimension of length, depth and diameter. In addition the shape was also described. A student t-test was used to calculate the linear dimension difference, while a One way analysis of variance was done to study the relationship between skeletal type and sella size. Sella turcica presented with normal morphology in the greater part of the subjects [66.7%]. No significant difference was found in linear dimensions between males and females. When skeletal type was compared to sella linear dimensions no significant difference was found in any of the three dimensions as in length, depth or diameter
