Abstract :

Determination of sex from human skull is of great importance for anatomists, anthropologists and forensic medical personnel from medico-legal point of view. Present study investigated the presence of sexual dimorphism in the dimensions, area and index of Inion-Opisthocranium-Asterion (IOA) triangle. 38 male and 32 female skulls were examined using Vernier slide calliper in the Department of Anatomy, IPGME&R, Kolkata. All the parameters were compared between two sexes. Male parameters were significantly (�P�< 0.05) higher than female parameters. The left IOA index of male (86.97%) was higher than right (85.73%). All other parameters were higher on right side in both sexes. The total area of IOA triangle was 2998.78 mm² in male and 2270.69 mm² in female. The anthropometry of IOA triangle can impart an immense value in sex determination of unknown individual.
