Background: Radiography plays a key role in forensics for the identification of humans especially in cases where the body is decomposed, fragmented, or burned. Radiography can help in giving accurate dimensions with the help of using certain formulae which can be applied for gender determination. It is reported in literature that maxillary sinuses remain intact, although the skull and other bones may be badly disfigured in victims who are incinerated and therefore, that maxillary sinuses can be used for identification of gender and age. Aim: This study has been carried out to check the accuracy and reliability of maxillary sinus in gender determination using morphometric parameters. Materials and Methods: Lateral cephalogram of 50 subjects (25 males and 25 females) were taken and morphometric parameters of maxillary sinus were analyzed using CS Imaging Version (8.0.20) software. Results: The mean area and perimeter of maxillary sinus in males was 1.7261 cm2 and 5.2885 cm whereas, the mean area and perimeter in females was 1.3424 cm2 and 4.3901 cm. Conclusion: It can be concluded that morphometric analysis (area and perimeter) of maxillary sinus using CS Imaging Version (8.0.20) software which can assist in gender determination.
