Sexual dimorphism in frontal sinus volume: A CBCT comparative study

Bones and teeth are parts of human body which are more resistant to decomposition. Owing to highly mineralised biological composition of this structure they tend to be indispensable in terms of forensic evidence. Morphometry of skeleton is the one of the many methods used for sexual dimorphism in forensic identification. Morphometry involves both linear as well as volumetric measurement. Like many other parts of skeleton, Frontal sinus is also of significant interest in forensic identification due to its individual characteristics which make the frontal sinus unique for every individual just as with finger print. This study was done with an aim of assessing the presence of dimorphism in frontal sinus among gender, based on analysis of frontal sinus volume using Romexis software of CBCT. The results showed that there is significant volume difference between males and females. Males are having higher volume when compared to females. So, it can be used in forensic personal identification.
