Background: The morphometric analysis of foramen magnum (FM) plays a crucial role in forensics and paleontology in identifying the gender of the unknown skeletal fragments. However, the reliability of these parameters vary among populations and races. The present study was conducted to investigate the reliability of the four foramen magnum parameters ie, foramen magnum transverse diameter, foramen magnum sagittal diameter, foramen magnum area and foramen magnum circumference in this native population. Methods: A total of 60 subjects belonging to both genders aged between 20 – 50 years who were undergoing computed tomography (CT) examination of head and neck region were selected for the study. The study sample comprised of 30 males in group A and 30 females in group B. The measurements were obtained from reformatted axial sections using helical CT scan. The FM sagittal diameter (FMSD) and the FM transverse diameter (FMTD) were measured by the greatest anteroposterior dimension and the greatest width of the foramen. The circumference (FMC) and the area (FMA) were obtained after tracing the bony margin of the FM on the CT image using CT workstation. Results: Mean values of all four parameters were found to be significantly higher in males compared to female subjects (P <0.001). Further, the accuracy of sex determination analyzed using the discriminant equation was 70% for males and 80% for females with overall accuracy of 75%. The predictability of gender was higher in female subjects than in male subjects. Conclusion: The dimensions of the foramen magnum can be used in gender determination of skeletal fragments with considerable accuracy. The Helical CT scan plays a pivotal role in providing accurate dimensions of the foramen magnum that could be useful in forensic testing.

Introduction: Foramen magnum is a large opening located in the occipital bone of the skull. The morphometric analysis of foramen magnum is clinically and surgically important because vital structures passing through it may suffer compression such as in cases of achondroplasia, brain herniation and meningiomas. Objectives: To study morphometric analysis of foramen magnum in dry human skulls and to measure its anteroposterior diameter, transverse diameter and foramen magnum index. Material & Methods: 100 dried human skulls of unknown age and sex were obtained from Department of Anatomy, Rama Medical College and GSVM Medical College, Kanpur, Uttar Pradesh, India. Deformed samples were excluded. Different parameters were measured with the help of Vernier caliper. Results: The mean antero-posterior diameter of foramen magnum was 33.79mm. The maximum antero-posterior diameter of foramen magnum was 40mm and minimum antero-posterior diameter was 28.2mm.The mean transverse diameter of foramen magnum was 28.30mm.The maximum transverse diameter of foramen magnum was 36mm and minimum transverse diameter was 21.5mm.The mean index of foramen magnum was 84.14mm. Conclusion: The morphometric analysis of foramen magnum and its variation is important not only for anatomists but also important to the anesthetists, neurosurgeons, orthopedicians and radiologists ; while planning and performing cranio-vertebral junction procedures.

Background: The Foramen magnum is an important landmark present at the base of the skull, it serves as a transitional zone between spine and skull. It is closely related to vital structures such as medulla oblongata, meninges, anterior and posterior spinal arteries, vertebral arteries and spinal accessory nerve, passing through it hence thorough knowledge of foramen magnum is required. These structures passing may undergo compression in case of foramen magnum herniation, meningiomas and foramen magnum achondroplasia. Aims: The present study aims in performing the morphometric analysis foramen magnum and to classify it based on its shape. Materials and methodology A total number of 64 adult dry human skulls were evaluated from the Department of Anatomy, ESIC MC & PGIMSR, Rajajinagar, Bengaluru, Karnataka. Results: The mean antero-posterior diameter was found to be 34.10 ± 2.63 mm, mean transverse diameter was 28.07 ± 1.87 mm, with mean area of 752.07 ± 111.97 mm2 and foramen magnum index was 1.21 ± 0.12. The foramen magnum shapes were classified as oval (30%), circle (12%), hexagonal (3%), pentagonal (5%), egg (17%), leaf (6%), irregular (27%). Conclusion: The morphometry along with other parameters can be used for sex determination in partially damaged skull bones of unknown individuals. The obtained data is useful not only for anatomists but also the neurosurgeons, otorhinolaryngologist and radiologists. Keywords: Foramen Magnum, Morphometry, Meningioma, Achondroplasia, Antero-Posterior Diameter, Transverse Diameter, Foramen Magnum Area, Foramen Magnum Index.

The objectives of the present study were to determine the type and morphometric measurements of Foramen magnum (FM) in dry human skulls of Dakshina Kannada district of Southern India. Material and Methods: The present study included 50 adult human skulls of which 32 were males and 18 females. The type of foramen magnum observed macroscopically. Antero-posterior (APD) and transverse diameters (TD) were measured by using stainless steel electronic digital callipers. Foramen magnum Index (FMI) was calculated by using formula FMI = APD/TD. Results: Present study observed 4 types of shapes of foramen magnum, among them ovoid type was found higher frequency (48%). Antero-posterior diameter is a distance between Basion and Opisthion 34.95 mm in males and 34.58 mm in females out of 34.81 mm. The transverse diameters 28.66 mm in males and 28.84 mm in females out of 28.73 mm. Foramen magnum index ≥ 1.2 was considered as ovoid and found in 56% of skulls. Conclusion: We believe that the present study provided additional information about the morphology and morphometric analysis of foramen magnum which is important to radiological, and neurosurgical literature.
