Background: Determination of sex of the skeletal remains plays a vital part in the identification of an individual. This study is focused on the morphometric measurement of the foramen magnum region and examining the accuracy of sexual dimorphism in the Nepalese population. Methods: Measurements were obtained from 3D computed tomography (CT) scan of 261 Nepalese adult cranial bases with known age and sex. Length and breadth of the foramen magnum, length and breadth of right and left occipital condyles and maximum and minimum intercondylar distance were measured on the base of the skull CT images. Results: The mean values for all parameters were higher in males than females except for the maximum intercondylar distance. Sex prediction done with discriminant function scores could classify the skull with an overall accuracy of 70.5%. Conclusions: It can be concluded from the results that the morphometric study of the foramen magnum is not suitable for sex determination in the Nepalese population. ; The measurements thus obtained were then noted into a proforma and then entered into IBM SPSS Statistics software v 25 and analyzed. The normal distribution of the data was determined by normality plots. The continuous variables were presented as mean ± standard deviation (SD). Male-female differences were tested using an independent t-test and the significance level of the test was defined at p<0.05. Pearson test was applied to examine the correlation between the measured foramen magnum dimension in both sexes. The foramen magnum dimensions were further analyzed using discriminate function analysis using a step-wise method for sex predictability. ; The present study was a descriptive cross-sectional study conducted upon the three-dimensional computed tomography (3DCT) images of the base of the skull of 261 Nepali individuals whose age and sex were known. All the CT images during the study period were from adults who presented to the Department of Radiology of Lumbini Medical College Teaching Hospital, Palpa for the ... |
