AbstractIntroduction: Morphometric and morphological study of cranium can be helpful in sexual dimorphism. Cranium is the second to pelvis in determining the sexual dimorphism. Fractures of the skull bones are common. Among the fractures nasal bone fractures are more common. Then comes the maxilla and mandible. Various factors can influence the facial bone fractures. They are motor car accidents, sports injury and boxing. Many works have been done on skull bones. The contribution on the study of anterior nasal spine was very less. Only two such case reports have been reported. Considering all these factors an attempt is made to correlate the anterior nasal spine between male and female dried skulls as well as in cadavers. Material and Methods: The study was conducted on 32 dried skulls and in 18 cadavers. 20 male and 12 female dried skulls were segregated. The cadaveric dissection includes 13 male and 5 were female cadavers. The morphometric parameters like Vertical Length, Anteroposterior length and breadth were measured by ruler and Vernier calipers. All parameters were spastically analyzed. Results: All parameters were less in females as compared to males. Conclusion: It was observed that the mean values of vertical length (VL), breadth(BD) and anteroposterior length(AP) of nasal spine were greater than in males as compared to females which was statistically insignificant.
