Abstract: Introduction: Foramen Magnum is the largest foramen in the base of the skull which gives passage to vital structures such as medulla oblongata continues as spinal cord along with meninges, spinal arteries, vertebral arteries and spinal accessory nerve. The present study was carried out to determine the sex of the skull based on the morphometric analysis of foramen magnum.

Introduction: Sex determination is one of the principle indicators of identity. The skull is the second best part of the skeleton to be used for sex determination after the pelvis. Sex determination from cranial fragments becomes essential especially when only a part of the skull is brought for identification. Aim: The present study was aimed to demonstrate the sexual dimorphism of the orbit and the foramen magnum (FM) in a sample of Egyptian population in order to increase the number of parameters used for identification, and by consequence, the accuracy when these parameters are combined with each other. Subjects and Methods: The present study was done on 300 cranial CT scans of known gender, 168 males and 132 females, with age ranged from 18 to 65 years, who presented to the Department of Radiodiagnosis, Menoufia University for head computed tomography (CT) as indicated in the course of their management for diagnostic purpose from January to October 2019. The data were tabulated and statistically analyzed. Results: The results showed that the orbital height, width and index differences between males and females were statistically significant (P < 0.001). Significant difference was also observed in FM transverse diameter, FM anteroposterior diameter and FM area. Tetragonal shape of FM was the most common in both sexes of the study sample. Conclusion: The present study shows that Foramen magnum and orbital variables can be considered along with the other parameters of the skull for sex determination in forensic analysis.

Introduction:The foramen magnum (FM) is a large opening in the base of the skull. The dimensions of FM are clinically important because many vital structure passing through it, viz., the lower end of medulla oblongata, the vertebral arteries, and spinal accessory nerves. It may endure compression such as in cases of FM herniation, FM meningiomas, and FM achondroplasia. The knowledge of FM diameter is needed to determine some malformations such as the Arnold-Chiari syndrome, which shows expansion of the transverse diameter. Materials and methods: The present study was carried out on 75 dry human skulls of unknown age and sex belonging to Rajasthan population
