ABSTRACT

Background: Morphometric analysis of the foramen magnum of dry human skulls in North Indian population was carried out to demonstrate the anatomical variations in morphology. The dimensions of the foramen magnum are clinically important because vital structures passing through it may endure compression in diseases associated with foramen magnum like herniation, meningiomas and achondroplasia.

Objectives:  The knowledge of various dimensions of the foramen magnum and foramen magnum diameters are needed to determine some malformations like Arnold Chiari syndrome in which the transverse diameter is increased.

Materials and Methods: 298 dry skulls of adult human being were studied. Anteroposterior and Transverse Diameter were measured by using a Digital Vernier caliper. The cranial base was visually assessed for the shape of foramen magnum. Additionlly, the area and index of foramen magnum were also calculated.

Results: The mean anteroposterior and transverse diameter of the foramen magnum were 34.13±2.44 mm and 28.32±2.042mm.The mean area and index of the foramen magnum were 754.32±105.6 mm and 83.14±6.33mm  respectively

Conclusion: The anteroposterier diameter of foramen magnum was more than the transverse diameter  and around 66%  seen in foramen magnum  are oval shaped.

Key words: Morphometry, Antero-Posterior Diameter, Transverse Diameter, Foramen Magnum.
