MORPHMETRIC ANALYSIS OF FORAMEN MAGNUM AND OCCIPITAL CONDYLES IN HUMAN SKULL AMONG EASTERN POPULATION – A CASE STUDY.

Dr. Shweta Solan

Abstract :

The morphometric study of foramen magnum and occipital condyles are valuable aid for anatomical studies. The measurements are helpful for neurosurgeons for performing lateral transcondylar surgical approaches for reaching lesions in the middle and posterior part of cranial base1. These are also used by radiologist to diagnose Cranioverteal abnormalities2. Therefore the assessment of morphometrics of foramen magnum and occipital condyle is essential. The knowledge of foramen magnum diameters is needed to determine some malformations such as Arnold Chiari syndrome, which shows expansion of foramen magnum3.3The stability of cranioverteal junction depends largely on the morphometric data of the occipital condyles. 4,5 Therefore the assessment of morphometrics of foramen magnum and occipital condyle is essential.The aim of the study was to determine dimensions of foramen magnum and occipital condyles, and morphometric assymetry between right and left condyles and with respect to foramen magnum. 60 dry human skulls were studied and necessary diameters were measured using verniers callipers.
