The aim of this study was to determine the mean values of bilateral asymmetry of lateral part and auricular surface in sacrum. The measurements of right and left sides of the lateral and posterior breadths of the alae and the maximum height of the auricular surface were taken from a total of 37 male sacra with a millimetric compass. Then the asymmetry was calculated with an equation as: [(left side - right side)/right side)] x 100. As a result of this study, the mean values of the asymmetry of the maximum height of the auricular surface, lateral and posterior breadths of the lateral part were found to be 1.56 +/- 0.4 x 0.16 +/- 0.1 mm and 5.50 +/- 1.1 mm, and respectively. The measurements determined in this study, posteriorlateral ala breadths and maximum auricular surface height, were identified statistically significant larger in the left side but little was found greater in the right side.
