Estimation of the Cranial Capacity in Dry Human Skull Bones

Background: The Cranial capacity is a measure of the volume of the interior of the cranium, which is used as a rough indicator of the size of brain. Craniometric study is an important fractions of anthropometry that can be employed in thedetermination of cranial study of an individual. Cranial capacity like several bodily dimensions are affected by environmental, ecological, biological, geographical, racial, gender and age factors. Methods: The study will constitute 60 dried human skulls belonging to both sexes in the department of Anatomy, at Indira Gandhi Institute of medical sciences, Patna. And help of other medical college patna city. The skull was placed on the rubber ring and the length of the skull was measured from glabella to inion, breadth by the distance between the two parietal eminences above zygomatic arch and the height from the basion [anterior margin of foramen magnum in the median plane) to bregma by spreading caliper and measuring tape respectively. Conclusion: The mean, SD of cranial length, cranial breadth and cranial height of both male and female skulls are mentioned in the table: 6. The mean cranial capacity and SD in male and female skulls were 1275.33cc +/- 124.68cc and 1213cc +/- 138.66cc respectively by direct method and 1344cc +/- 106cc and 1276cc +/- 68cc respectively by calculatedmethod. There was a significant difference between genders (p <0.001).The mean, SD of cranial length, cranial breadth and cranial height of male skulls were more compared to female skulls. In the present study, the significant difference isfound in the cranial capacities of male and female skulls. Keywords: Skull, Cranial capacity.
