Abstract

Establishing the Identity of a person is one of the biggest challenges faced by forensic pathologist in cases where the body has either decomposed or has been mutilated by the perpetrator of a crime. Without the establishment of the identity of the body the investigation cannot proceeds further. When a mutilated or decomposed body have been recovered then the Identification of the individual can be done in a step by step approach, in that identification of sex is one of the most important steps. Sex can be established by various methods. Determination of the sex by bones is one of the important steps when a bag of bones have been recovered. Most bones are used to identify the sex of the unidentified bag of bones. Most of the bones shows sexual dimorphism and various studies have been conducted using various bones. In the present study we have used Hyoid bone for correlating the bone with the of sex of the individual. In this study 116 hyoids were studied which were collected from the autopsies conducted at the mortuary of a Medical College in Western Maharashtra. The collected hyoids had 58 Males and 58 Females. The minimum age of the subjects was 20yrs and the maximum age was 80yrs. Present study was able to establish the sexual dimorphism of the hyoid bone with respect to the five parameters measured. In the present study the discriminant function analysis developed using all the five variables showed 91.4% accuracy in classifying male hyoids correctly and 100% accuracy in classification of female hyoids. This discriminant function can be used for determination of sex of the recovered hyoid bone.

Keywords: Hyoid bone, Sex determination, Discriminate Function, co-relation.
