Introduction: The sella turcica has gained importance as a stable bony landmark in cephalometric studies.
Aim of the work: The aim of the work was to explore the changes that accompany postnatal ontogeny of the sella turcica until full development, and to verify its contribution in age estimation and sexual assignment among Egyptians.
Subjects and methods: Six selected measurements of the sella turcica of 215 Egyptian patients were assessed using Multidetector Computed Tomography (MDCT). The patients represented different ages and were referred to the Radiodiagnosis and Intervention Department. The gathered data were then subjected to statistical analysis including correlation and regression analysis.
Results: The measurements of the sella showed a strong correlation with age. Three selected measurements demonstrated significant sexual dimorphism (sella width, sella height anterior and median in the subjects aged 20 to 25 years). Six regression equations were derived. The accuracy achieved by the combined parameters in the younger group (aged less than 25 years) was higher than that of the older individuals.
Conclusion: The results achieved from the current study are useful tools in the determination of age and sex in both forensic and bio-archeological disciplines. However, further studies concerning the shape are strongly suggested.
