Correlative Study of Cranial Index with Cranial Capacity in South Indian Crania

Abstract

In the present study 540 dried, non-pathological crania were studied cranial index was measured by spreading caliper and cranial capacity was studied by filling mustard seeds through foramen magnum. There was significant correlation between these two values. Mean value of cranial capacity was 1171.24(SD=113) and cranial index was 75.13(SD=3.47). Regression equation of cranial index and cranial capacity were linearly accepted with significant P<0.008 value cranial capacity (x) = 1452.63 37y and cranial index (y) = 79.27 - 0.004x. By known cranial index the cranial capacity can be anticipated and vice versa. This study will help the clinician by providing base line data, Medico-legal expert, Neurosurgeon, Radiologist in their respective fields. Anthropologist to identify race and sex. These present values differ with previous foreign workers hence this study indicates the regional significance.
