ABSTRACT
Background: The bregma is an anatomical point of the skull located where the coronal suture intersects perpendicularly to the sagittal suture . It is the meeting point of the frontal bone and the parietal bone . Sutural bones of the cranial vault are formations associated with insufficient rate of suture closure, and regarded as epigenetic and hypostatic traits. These bones rest along sutures and / or fill fontanelles of the neonatal skull. Sutural bones at pterion and lambda more come but at bregma it is unusual. There are very few study worked on bregma sutural bone. The present study aim is to find out the incidence of bregma sutural bones.
Materials and Methods: Total 500 skulls were used for this study from different medical institutions of south India.
Results: Out of 500 skulls, only five skulls (1%) were found with bregma sutural bones.
Conclusion: Bergama sutural bones shows the possibility of discrete diversification of the ossification centers, as well as the relative stability of the structural skull matrix in response to discrete changes. Knowledge of this variation is very important for anthropologists, radiologists, orthopedic and neurosurgeons.
Key words: Sutural bones, Anterior fontanelles, Bregma, Skull.
