In the present study an attempt has been made to establish standards for sex determination from the various direct and indirect measurements of the cranium. A total of 100 cranium (50 of either sex) were measured for nine direct measurements pertaining to Mastoid triangle and Opisthion-Bimastoid triangle. These measurements were used further to calculate four indirect measurements pertaining to the calculation of Opisthion-Bimastoid triangle area and angles. %26lt;br%26gt;Analysis of data reveals that the male crania exhibit greater values for all the measurements except the angle right Mastoidale-Opisthion-left Mastoidale. The sex difference has been observed to be statistically significant for all the measurements except for the angles of the Opisthion-Bimastoid triangle. Sectioning point was calculated for the diagnosis of sex based on the mean values of these measurements; the accuracy of sex determination varied from measurement to measurement. The highest value for determining sex was obtained for Asterion-Mastoidale length of right side i.e. 80%, followed by Bimastoid breadth i.e. 75%. This suggests that these measurements could be used with relatively high degree of accuracy in determining sex of the unknown crania.
