Abstract

Background: The foramen magnum is a critical anatomical landmark at the skull base, facilitating the passage of the brainstem, spinal cord, and associated blood vessels. Its dimensions and shape are known to vary across populations. Cranial morphology, encompassing the overall form and size of the skull, can also exhibit population-specific characteristics. This study aims to explore the potential correlation between foramen magnum size and shape with cranial morphology in a sample of dry human skulls from Central India.
Materials and Methods: A defined sample size of dry 56 human skulls of known Central Indian origin will be obtained. Ethical considerations regarding informed consent will be addressed if applicable. 1. Foramen magnum: Anteroposterior and transverse diameters will be measured using standard osteometric instruments (e.g., calipers). The foramen magnum shape will be categorized based on established criteria (e.g., oval, round, pentagonal). 2. Cranial morphology: Standard cranial measurements will be taken following established protocols to capture overall cranial size and shape (e.g., cranial base length, breadth, cranial vault measurements).
Statistical Analysis: The collected data will be subjected to appropriate statistical tests to assess potential correlations between foramen magnum dimensions/shape and cranial morphology.
Results: The analysis revealed the average size and shape of the foramen magnum in the North Indian population sample. The study explored correlations between foramen magnum dimensions (area, index) and cranial measurements. The results shed light on potential variations in foramen magnum morphology and its connection to overall skull form in this specific population group.
