    Introduction: Facial anthropometry plays an important role in forensic investigations especially in identification of decomposed bodies from skeletal remains. Dimensions of nasal bone is one such parameter that can be used to determine sex. The main aim of the study is to compare the morphological measures of nasal bone between genders using computed tomography. Method: Retrospective study including the patients visiting the Dept. of Radio-diagnosis and Imaging, Kasturba Hospital, Manipal. Based on the inclusion and exclusion criteria 240 subjects (120 males and 120 females) who were referred for routine CT OMC were included in the study. The axial sections were converted into coronal and sagittal slices using the multiplanar reconstruction tool. Three anthropometric parameters were measured. Results: A total of 240 (120 males and 120 females) data was obtained with age group ranging from 20-50 years. Mean and Standard deviation was calculated. The data was normally distributed hence independent sample T test was performed to find the difference between males and females. Null hypothesis stated that there was no significant difference based on the anthropometric measurements between the males and females since the (p>0.05). Alternate hypothesis stated that there is significant difference noted between the males and females as (p<0.001). Conclusion: In present study, three measurements of the nasal bone were taken such as the nasofrontal angle, pyramidal angle and the linear distance out of which two variables i.e. the pyramidal angle and the linear distance were good discriminators which contributed high accuracy in comparison to the other parameter.
