Abstract

The purpose of this study was to grasp the morphological characteristics of Jeju population's skulls and investigate the differences of the anthropological characteristics in comparison with those of several samples from the Northeast Asia and Korea. Data analysis has been carried out on the skull and angiographic of two hundred normal adults that had been taken with the multidetector-row computed tomography at Jeju National University Hospital between July, 2005 and August, 2007. The results were as follows. Out of the 30 criteria of the skull metric traits, 28 show measurement differential between male and female. The mean of man was greater than that of woman (p<0.05). The groups were classified into three categories: Chinese and Japanese group, Korean and Jeju population group, Mongol group as the result of the group analysis using eleven data (maximum cranial length, maximum cranial breadth, maximum cranial height, facial width, upper facial height, nasal height, nasal breadth, nasal index, cranial length breadth index, cranial length height index, and cranial breadth height index). There were four types dolichocrany (1.0%), mesocrany (13.5%), brachycrany (42.0%), hyperbrachycrany (43.5%) of skull in Jeju populations using the cranial length breadth index (p<0.05) and sex of skull types were not significant. We confirmed the difference in the size of the skull according to the human community by race, nationality, region and sex. There was close correlation between Korean and Jeju population of anthropological characteristics.
