The shape and size of sella turcica in skeletal class I, II and III Pakistani subjects.
Pak J Surg Jan ;37(4):283-90.

The purpose of this study was to establish relationship between the shape and size of sella turcica and its correlation with skeletal class I, II, and III Pakistani subjects to determine the differences in gender, age and skeletal patterns. In this study, lateral cephalometric radiographs of 350 individuals between the ages 7-60 years were selected. Manual tracing was used to calculate the length, depth and diameter of sella turcica. Morphological aberrations types were identified. Results showed variation in morphological appeaarance in majority of subjects (76 percent). No significant difference in linear dimensions between genders could be found. When age was evaluated, significant differences were found. Sella size of older age group was larger than in the younger age group. Signifi cant difference was found in diameter of sella between class II and class III subjects. Larger diameter values were present in class class III subjects, while smaller diameter sizes were apparent in class II subjects(multiple comparison test). When gender, age and type were all compared with the size of sella (regression analysis), age was significantly related to change of length, depth and diameter. Results of the current study can be used as a reference standards for further investigations involving the sella turcica area in Pakistani subjects.
