RESUMO

This study was aimed at evaluating the sexual dimorphism with respect to overall incidence, number and location of wormian bones. Adult dry human skulls (n=180) of known age and sex available in the Department of Anatomy, St.John’s Medical College, Bangalore were included in the study. Overall incidence of wormian bones was more in female (64.80%) than in male skulls (40.20%). They occurred more frequently at lambdoid suture (60%). Wormian bones along the coronal suture and at bregma were seen only in male skulls, while intra- orbital wormian bones were seen only in female skulls. Wormian bones along the sagittal suture showed sexual dimorphism (27.78%, p= 0.045) while at lambda and lambdoid suture showed a good discriminating power of 17.65% (p=0.087) and 21.43% (p=0.089) respectively. This study concludes by stating that, there exists a moderate degree of sexual dimorphism among the wormian bones with respect to overall incidence, number and location.
