Incidence of Wormian Bones in South Indian Skulls: A Study on Cadaveric Dry Skulls

Abstract

Background: Wormian bones, also called as sutural bones, are small bones found in the sutures of skull. These bones may be found as normal variants in the skull or may be associated with some of the congenital abnormalities. Materials and Results: In our study, done on 110 dry adult human cadaveric skulls, we have identified 76 skulls with wormian bones (69.09%). Highest number of wormian bones was at the lambdoid suture, with 50.04% and next at the lambda, with 9%. Conclusion: The current study on wormian bones will add further knowledge to the available data about wormian bones and it will be of help for neurosurgeons, orthopedic surgeons, pediatricians, radiologists and anthropologists for proper diagnostic and therapeutic purposes.
