Abstract

Background: Foramen magnum is situated in the posterior cranial fossa in anteromedian position. It is of great importance  in anthropology, forensic medicine and skull base surgeries.

Objective: Calculate anteroposterior (AP), transverse diameter(TD), area of foramen magnum and to observe its various shapes.

Materials and Methods: 50 dry human skull bones of unknown sex was obtained from anatomy department. Measurements were taken by vernier calipers .SPSS 16 was used to calculate mean and standard deviation.

Results: Mean AP diameter was found to be 33.64±0.228 mm, mean TD was   27.040±0.214 mm and Mean area was 714.99±0.844 mm2. Oval shaped foramen magnum was the most common variety (46%). 20% was tetrahedral,16% round ,14% egg shaped 2% hexagonal and 2% irregular.

Conclusion: Present study focuses on morphometric and morphological variation in foramen magnum. This will be useful for anatomists , forensic experts , radiologists and  neurosurgeons.

Key words: Foramen magnum, Anteroposterior, Transverse, Diameter,  Area.
