ABSTRACT:

Objective:  The purpose of the present study was to assess the morphometric values of foramen magnum to evaluate sexual dimorphism as well as its clinical importance.

Materials and Methods:  The study was conducted on 100 (Male 56, Female 44) CT scans. Morphometric study was conducted on foramen magnum of occipital bone. From all the CT images the foramen magnum anteroposterior diameter and transverse diameter were measured.  Area of foramen magnum was calculated automatically. Foramen magnum index was calculated by using the formula Ht/Br×100. The data was statistically analysed.

Results: The mean anteroposterior diameter in males and females was 33.9± 2.78, 32.2 ± 2.24, the mean transverse diameter in males and females was 27.7±2.27, 26.7± 2.68 and the area of foramen magnum in males and females was 739.5 ±9.96 , 676.1 ± 8.76,  index of the  foramen magnum in males and females was 82.09±7.86, 83.02±9.55respectively

Conclusion: This study concludes that the parameters measured were higher in males compared to females except foramen magnum index. This was noticed higher in females than males.

KEY WORDS: Foramen magnum, Computed tomographic images, Morphometry.
