    Introduction: Foramen magnum is the largest oval aperture transmits medulla oblongata with meninges, vertebral arteries, and spinal branches of accessory arteries. The orbital cavity is an important anatomical space where eyeball and its associated structures were present. Materials and Methods: The analysis of foramen magnum and orbit in 35 dry Indian skulls was measured using Vernier caliper, scale, and marker. Results: The present study has observed the shape of the foramen magnum shows a marked occurrence of tetragonal 15% and oval shape 13% of foramen magnum when compared to the egg shape 3%, hexagonal 3%, and pentagonal 1%. In tetragonal shape, the mean value of vertical diameter was 3.5003 mm and transverse diameter was 3.04333 mm. In oval shape, the mean value of vertical diameter was 3.546923 mm and transverse diameter was 2.99615 mm. In hexagonal shape, the mean value of vertical diameter was 3.3866 mm and transverse diameter was 3.1833 mm. In egg shape, the mean value of vertical diameter was 3.476667 mm and transverse diameter was 3.20667 mm. In pentagonal shape, the mean value of vertical diameter was 3.24 mm and transverse diameter was 2.84 mm. The mean value of orbital index between the right and left was 86.5533 mm and 83.797 mm. Conclusion: The present study shows that there is a more occurrence of tetragonal and oval shape compared to hexagonal, pentagonal, and egg shape. In concern with measurement of axis of foramen magnum, the vertical axis is higher than that of the transverse axis. Besides that, orbital cavity index of our present study has observed no marked changes between the right and left sides.
