DEL SOL, Mariano. Cephalic Index in a Group of Mapuche Individuals in the IX Region of Chile. Int. J. Morphol. [online]. 2005, vol.23, n.3, pp.241-246. ISSN 0717-9502.

Native Mapuches live mostly in the Chilean Araucania in the IX Region of the country, being most isolated those living along the coastline. Several factors are considered to be determining in their head shape and indexes, among which ethnic aspects can be pointed out. Fifty male native Mapuche individuals, all adults living in the coastal range of the IX Region of Chile, with ages ranging between 19-83 years, were anthropomorphically studied. Their cephalic diameters were measured and their cranial index determined. The mean of the greatest anteroposterior diameter (frontal-occipital) was 184mm (DS6) with superior limits of 185 mm and inferior 182 mm. The mean of the transverse maximum diameter was 148 mm (DS4) with superior limits of 149 mm and inferior 140 mm. The mean of the cranial curves were: anterior-posterior 395 mm (DS13), supra auricular 315 mm (DS12) and maximum circumference 632 mm (DS20). In the 66% of the individuals were mesocephalic, 28% brachycephalic, 4 % hyperbrachycephalic and 2 % dolichocephalic. The mean of cephalic index was 80.4. Native Mapuche individuals present typical mesocephalic characteristics and a clear tendency to brachycephalization. The data obtained, anatomical and anthropological, will add up to Biological and Physical Anthropology and benefit the knowledge of health professionals
