Brief Summary

Sexual dimorphism from skeletal remains a crucial step towards biological profile reconstruction since these are some of the last structures to remain after death. Paranasal sinuses remain intact even in extreme situations and are able to resist adverse environmental conditions due to their unique properties. The maxillary sinus is the largest of all paranasal sinuses and is considered as characteristic entity like human fingerprints for each person. Also, sphenoid air sinus is located deeply in the skull and is enveloped by different structures inside the sphenoid body. It is the least possibly affected by external deteriorating factors. Owing to limited research on the Egyptian population on the role of 3D volumetric assessment of paranasal sinuses in forensics, this study will be designed to investigate the significance of the volume of both sphenoid and maxillary sinuses in sexual discrimination.
