ABSTRACT:
Introduction: Determination of sex is of crucial importance in forensic investigations, when only a part of the body or skeletal remains are available. The present study focussed on the sexual dimorphism of hyoid bone in Telangana population by using morphometric analysis.
Materials and methods: The present study was carried out on a total of 60 hyoid bones in which 30 were of male and 30 were of female individuals. The bones were obtained from the department of Anatomy, Osmania Medical College and Deccan College of Medical Sciences, Hyderabad. Damaged and deformed bones were excluded, and only fully intact bones were included in the study. Lengths of greater horns, lengths of lesser horns, total hyoid length, and distance between distal ends of right and left greater horns, width of the body, length of the body and the thickness of the body of hyoid bone were measured by using sliding calipers.
Results: All parameters showed significant difference between the male and female groups. The measurements of all the parameters were significantly higher in males than in females.
Conclusion: All parameters used in the present study confirmed sexual dimorphism in hyoid bone. Hence, hyoid bone can be considered in forensic investigations or anthropological studies to determine the sex of an individual.
Key words: Sexual dimorphism, Hyoid bone, greater horn, Lesser horn, Sex determination.
