Incidence of bregmatic bone in north Indian skulls.

ABSTRACT

Background and objective: Studies of non-meteric cranial variants have been a field of considerable interest to research workers specially because of their racial and regional importance. Supernumerary ossicles (or Wormian bones) of the cranial vault are formations associated with insufficient rate of suture closure. It was reported that there exists racial variability among the incidence of these bones. Material and methods: Studies of fifty north Indian skulls of Rohilkhand Medical College Bareilly and Shri Ram MurtiSmarak Institute of Medical Sciences, Bareilly, U.P. were studied for the incidence of Bregmatic bone cranial variant. Results: In our study the incidence of bregmatic bone was 4%, which was higher than reported elsewhere. Conclusion: The findings are discussed in the light of available literature and are of considerable racial and regional significance. We believe that the knowledge of bregmatic bone is of importance to the neuroanatomists, neurosurgeons, radiologists, anthropologists, paediatricians and morphologists.
