Forensic Significance Of Symmetry Through Testing Bony Landmarks On Skull

Objective:To study the symmetry of 11 bony landmarks on skull and ensure it’s misregistration. This study was designed to test the scale of misregistration of symmetry of skull with 11 bony landmarkes.Method:Image of 84 male skulls and 21 female skulls were captured with bony land marks signed with the device of photographic superimposition. All images reached flip horizontal with the same software. Distance between the relevant bony landmarks was measured after superposing the folded (left or right) half image with the other half according to the central line.Result:Skulls tested were not strictly symmetrical according to the central line that there is certain misregistration between landmarks of two sides. The bony landmarks reached general symmetry expect the gonion and mental foramen point. Additionally, the frontotemporal point, orbitofrontal zygomatic point, temporal zygomatic, orbital tubercle and frontal temporal ridge reached considerable accurate symmetry with misregistraiton less than 1mm.Conclusion:Symmetry of Frontotemporal points, orbitofrontal zygomatic points, temporal zygomatic, orbital tubercle is considerable accurate in skull which suggesting that those landmarks could be used to repair and revise broken or incomplete skull as functional indicators for repair and correction use.
