AbstractBackground: Foramen Magnum is a large oval shaped opening in the posterior cranial fossa. It is a very important feature in bipeds. The knowledge of the dimensions and the shape of the FM has important clinical implication in prognosis and treatment of various neurological pathologies like Arnold-Chiari Syndrome and posterior cranial lesions. Morphometric parameters of FM are of great importance to Orthopaedician, Neurosurgeon, Radiologist and Anthropologist to achieve the best exposure with appropriate surgical outcome.
Methods: a total of 30 dried human skulls were procured from the department of Anatomy, GMC Jammu from June 2021 to January 2022. The anterio-posterior diameter and the transverse diameter were measured using Vernier calliper. A detailed morphometric analysis and the shape of FM is then noted and analysed.
Results: The mean Anteroposterior diameter of FM was found to be 35.11±2.211mm and the mean Transverse diameter of FM was found to be 25.19±2.78mm. The average FMI was found to be 1.39±0.13. Out of 30 skulls, the shape of FM which was most frequently observed was Oval, found in 12 skulls, 6 were Hexagonal in shape. The 2nd commonest shape was tetragonal, seen in 8 skulls and the least common was Round, seen in only 4 skulls.
Conclusion: Although the sample size was small and there was no gender discretion. Still the study can prove to be helpful to Anatomists, Radiologists and Surgeons. As the morphology of foramen magnum is variable, it is also important in evolution. It is also important for treatment of the Arnold Chiari’s Syndrome, where the dimensions are needed prior to cut-off the Foramen magnum in posterior cranial fossa lesions
