Abstract

This study, Measurements of Foramen Magnum Using Computerised
Tomography in Sokoto State, Nigeria was aimed at assessing the
anteroposterior diameter and width of the foramen magnum, the
anteroposterior diameter and width of the occipital condyles as well as
the bicondylar distance taken from normal cranial CT scans of subjects
with the aim of determining the sex of the subjects as was previously
employed by Selma-Uysal, et al 2005 in Turkish population. Cranial CT
Scans were obtained from the local data base of the CT machine and
back up compact disc from the CT library. Films were viewed on the
computer monitor. Measurement was made with Dragon V3.1.1 Philips
and Neusoft Medical System Company Limited software, the software
provides a meter rule with which measurements were done. A total of 240
subjects were involved in the study, out of which, 73.75% were males. The
ratio of male to female was 2.8:1. The age range of the subjects used in
this study was 20 to 79 years. The range of the foramen magnum diameters
were 22.3mm to 45.9mm for anterior posterior diameter and 19.9mm to
38.3mm for the width of the foramen magnum. The mean anterior posterior
diameter and width of the foramen magnum were 34.3mm and 30.1mm
respectively. This study reports that the dimensions of the foramen magnum
are greater in Nigerian males than in their female counterparts and are
statistically significant for width of the foramen magnum. The increase in
age of individuals after the age of 20 years will not affect the foramen
magnum diameters.
