ABSTRACT:

Introduction: Foramen magnum is a wide opening present in the occipital bone of the cranium. Morphometry of foramen magnum are important because vital structures pass through it and for sex determination of skulls. The aim of the present study was to conduct morphometric analysis of foramen magnum.

Materials and Methods:  Completely ossified 162 adult human dry skulls of unknown age and sex were taken from the Department of Anatomy of Gadag institute of medical sciences, Gadag. The skull samples which were deformed were excluded from the study. The antero-posterior and transverse diameters were measured using a digital vernier caliper graded upto 0.01mm. The statistical analysis was carried out and the results were tabulated.

Results: The longitudinal diameter of the foramen magnum in the present study was between 31 – 36 mm   with a mean of 33 mm + 1.4 (Mean + SD). The transverse diameter was between 25 mm -30 mm with a mean of 27 mm + 1.6.

Conclusion: Knowledge of foramen magnum measurements are useful for anatomists, neurosurgeons, radiologists, and also anthropologists. The data obtained will be useful to the neurosurgeon in understanding the anatomy of craniovertebral junction in a newly described transcondylar approach for brain stem lesion particularly in preoperative assessment.

Key words:  Skull, Foramen Magnum, Morphometry.
