Gender determination of unknown - A CT guided study on the dimensions of frontal sinus
Journal Title: Medpulse International Journal of Forensic Medicine - Year 2018, Vol 5, Issue 1
Abstract
Background: Gender and age estimation is considered as an important problem in the identification of an unknown skull. The paranasal sinuses by origin shows a significant variations among individuals. The frontal sinus dimensions were considered to be particularly significant. It is considered to be a useful tool for gender determination of unknown human skulls in the field of forensic medicine. Aim: To evaluate the fundamental importance and reliability of Frontal sinuses using CT measurements to aid in gender identifications Methodology: CT images of 106 individuals (male – 50 nos., female – 56 nos.), with the age ranging from 20 years to 50 years, were selected for the study. Anthropometric measurements of their frontal sinuses were studied. The width and the height of the frontal sinus were measured. Results: Discriminative Analysis predicted the gender with an accuracy of 30% in males and 100% in females with an overall accuracy rate of 54.6%. Gender determination using width and height of the frontal sinus on both sides showed that left frontal width is statistically significant. Conclusion: Gender determination with a fair degree of accuracy can be predicted using the various parameters of the frontal sinuses using Computed Tomography (CT), especially when the skull is the only source of evidence in the absence of whole skeleton.
