Abstract

The frontal sinuses of 829 crania from Kyoto, Kinki, Hokuriku, Ryukyu, Ainu, Korea-China, and Jomon populations were examined radiographically, and their measurements such as height, width and area were compared between these 7 populations. All the measurements except for the area, and square roots of the total area show normal distributions. No bilateral differences was noted, but sex and age differences were significant. Multivariate tests suggest that the most significant coefficients separating the 7 populations is not size but shape of the frontal sinuses, the proportion of the height to the breadth in particular. This index discriminates the Jomon-Ainu-Okinawa populations from the three local populations of Japan and Korea.-China population.
