Characterization and Measurement of Sella Turcica among Sudanese using CT

Abstract

This is a descriptive analytical study on the sella turcica , describes its shape and measures the linear dimension; length, depth and diameter in normal Sudanese subjects. Brain CT scan scout of 50 individuals (25 males and 25 females) with a mean age of 37.5 years were taken and studied according to gender, age, height and weight. The sella turcica on each radiograph was analyzed and measured to determine the shape of the sella, in addition to the linear dimensions of length, depth, and diameter. Excel 2007 program is used for the analysis of the data. The main objectives of this study were to characterize the sella turcica in sudan, and describes its shape and measures the linear dimension; length, depth and diameter in normal Sudanese. The results showed that the mean of the linear dimensions of the sella turcica in Sudanese were; (10.1± 1.6mm) for length, (7.7± 1.8mm) depth, and (11.8± 1.9mm) for diameter. The sella turcica presented with a normal morphology in the majority of subjects (56 percent). No significant differences in linear dimensions between genders could be found (T values>0.05). When age was evaluated, significant differences were found between the older and the younger age subjects, the sella length increases by 0.03mm starting from 8.9mm, the depth decreases by 0.04mm starting from 7.9mm, and the diameter increases by 0.02mm starting from 11.08mm, as the age increase by one year. When subjects height compared with the linear dimensions of sella the study found that the length increases by 0.02mm starting from 7.24mm, the depth increases by 0.01mm starting from 6.42mm, and the diameter ‫‪increases by 0.02mm starting from 9.05mm, as the height‬‬ ‫‪increases by 1 cm.The study also found that the length increases‬‬ ‫‪by 0.04mm starting from 7.88mm, the depth increases by 0.02mm‬‬ ‫‪starting from 6.65mm, the diameter increases by 0.03mm starting‬‬ ‫.‪from 10.23mm, as subject weight increases by 1kg‬‬
