Introduction:Computerized tomographic scan (CT scan) has been much useful mean for the study of calvarial thickness on living subjects. one of important advantage of using CT for the study of calvarial thickness on living subjects is one can assess, if any, gender and racial variation. CT has been much useful mean for the study of calvarial thickness on living subjects. one of important advantage of using CT for the study of calvarial thickness on living subjects is one can assess, if any, gender and racial variation.
Methods: It was a cross-sectional study. Multistage random sampling method was adopted for selection of samples. One hundred adult people, over 20 year,s age were studied. Out of them 56 were male and 44 were female. Those people who were referred in radiology department for CT Scan of head were studied. However those who had trauma to skulls, bony pathology of skull bones were excluded in the study. Thickness of frontal and occipital bone at various points in lower, middle and upper thirds and parietal bone in anterior, middle and posterior thirds were measured with the help of CT scan.
Results: The mean and standard deviation of thickness of Frontal bone was calculated as 5.8 ± 2.1 mm, Parietal bone as 5.4 ± 2.2 mm and Occipital bone as 8.6 ± 2.9 mm. In all cases there was no significant difference between right and left side points (p>0.05) showing that there was no bilateral variation in calvarial thickness in Nepalese. The present study observed, in all cases, no significant difference between male and female (p>0.05) proving that Nepalese calvaria showed no sexual dimorphism.
