A MORPHOMETRIC STUDY OF FORAMEN MAGNUM IN DRY ADULT HUMAN SKULL
Author: Kopal Saini
Aim: To study the morphology and morphometry of foramen magnum in dry adult human skull.
Materials and method: Ninety eight skulls were investigated for foramen magnum. The shape of foramen magnum was noted and classified into oval, round, tetragonal and asymmetrical. The length (antero-posterior) and width (transverse) of foramen magnum was measured using pair of dividers and ruler.
Results: 44 foramina magna were observed to be oval, 20 were tetragonal, 18 were round and 13 were found to be asymmetrical. The average length was 34.8 ± 2.45 (29-42) mm and average width was 30 ± 2.29 (26-36) mm. 3 skull showed occipitalization of atlas vertebra.
Conclusion: These data may be of use as a morphometric database for description of “normal” variants of foramen magnum morphology.
Keywords: Foramen magnum, Craniovertebral junction
