ABSTRACT:

Introduction: Cranial capacity is a measure of the volume of the interior of the skull of those vertebrates who have both a skull and a brain. Cranial capacity is used as a rough indicator of the size of brain. Cranial capacities like several bodily dimensions are affected by environmental, ecological, biological, geographical, racial, gender and age factors.

 Aim: The aim of the study is   to measure and calculate cranial capacity by direct and calculated methods and to classify the skull under different subtypes.

Materials and Methods: The study will constitute 100 dried human skull bones belonging to both sexes in the Department of Anatomy, Rajarajeswari medical college, Bengaluru.

Results:  The average cranial capacity by using direct method is 1275.33cc ± 124.68cc in male skulls and 1213cc ± 138.66cc in female skulls and by calculated method is 1344.10cc ± 106.62 cc in male  skulls and 1276.26cc ± 68.72cc in female skulls respectively.

Conclusion: The mean cranial capacities   of male skulls were higher than that of female skulls that tends to agree with similar studies conducted earlier. Thus, the cranial capacity of the male skulls is 5-15% higher than the female skulls.

KEY WORDS: Cranial capacity, linear measurement, packing method, Lee-Pearson formula.
