Abstract

The examination of skeletal remains is a most challenging task of forensic investigations. Determination of sex plays an important role in the skeletal examination since it reduces the field of search to 50% as the other sex in the missing population can be discarded from the study. This can be achieved by using various anthropometric methods based on measurements of bones. But most of the times the skeletal remains in question may berecovered in a broken or fragmented state. Hence it is important to use denser bones which are often recovered intact. The maxillary sinus is one of such bones present in the body.The present study was performed to discover the possibility of sex determination from radiologic measurements of dimensions of maxillary sinus among a known cross-section of South Indian population. In this study, by the use of Multidetector Computed Tomography (MDCT) scan, eight maxillary sinus measurements were assessed in 90 living non-pathologic South Indians comprising 46 males and 44 females aged 17 - 60 years referred to the Radiology Department. The data subjected to statistical analysis revealed the three variables (right antero posterior, left transverse and left cephalo-caudal of maxillary sinus) showing significant differences. In conclusion, MDCT measurements are useful feature in sex determination in South Indians.
