Background:The frontal bone is ossified in fibrous mesenchyme from two primary centers, one near each frontal tuber. At birth the bone consists of two halves. The median suture usually disappear by about 8 years, but may persist as the metopic suture. Metopic suture present at birth between the right and left halves of the frontal bone and closes at 2-5 years of the age, but may present during adult life. The suture closure began endocranially and it spread to pericranium. Materials and Methods:Total 500 skulls were used for this study from different medical institutions of south India.Results: Out of 500 skulls, 11(2.2%) skulls showed complete metopic suture and 108(21.6%) skulls showed in complete metopic suture. Conclusion:The Knowledge of metopic suture is very important in radiological and orthopedic surgeons during their practice in head injuries and it also important in practice of anthropologists and neurosurgeons.

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.
