Resumo: Metodos Craniometricos, tem sido regularmente aplicado na determinacao do genero em diversas regioes mundiais. Avaliar morfometricamnte o indice de confiabilidade de tre metodologias distintas para determinacao do genero na populacao brasileira. Foram avaliados 215 cranios humanos brasileiros com genero, idade e etnia identificados, pertencentes a Universidade Federal de Sao Paulo. Foram utilizadas as metodologias, do cranio, area do triangulo mastoideo e do forame magno, de acordo com os criterios, estabelecidos por Yscan & Steyn (1999), Kemkes & Gobel (2006) e Gunay & Altinkok (2000). Os valores obtidos foram submetidos a analise estatistica, calculo do coeficiente de correlacao Intra-classe, test t student, com nivel de significancia de 5%, regressao logistica multipla, odss Ratio, Mann-Whitney e ANOVA multivariada. A analise por meio do metodo craniometrico revelou que o genero influenciou (p<0,05) em todas as mensuracoes. Nao houve diferenca significante da posicao do processo mastoide entre os grupos etnicos e os generos (p>0,05), porem houve prevalencia do genero masculino sobre o feminino nas mensuracoes Po-Ms e As - Po (p<0,05). A analise estatistica (ANOVA e Tukey test) revelou que o genero influenciou na largura do forame magno, sendo os masculinos (30,3±0,20) maiores que os femininos (29,4±0,23), mas nao o comprimento (p<0,05). As tres diferentes metodologias empregadas apresentaram diferencas morfometricas entre os generos para as caracteristica craniofaciais do brasileiro. Portanto, em conjunto com outras tecnicas antropologicas pode contribuir para a determinacao do genero de individuos desconhecidos. Ver menos

Abstract: Craniometryc methods, has been regularly applied, for providing assistance in the gender determination in various regions in the worldwide. To evaluate morphometrically the reliability of three differents methodologies for gender determination in Brazilian population. Were evaluated 215 Brazilians human skulls with gender, age and ethnicity previously identified, belong to the Federal University of Sao Paulo. The following methodology, the skull craniometry, triangle mastoid area and foramen magnum, according to the criteria established by Yscan & Steyn (1999), Gobel & Kemkes (2006) and Gunay & Altinkok (2000). The datas were submitted to statistical analysis, Intra-class correlation coefficient, student t test, with level significance 5%, multiple logistic regression, odss Ratio, Mann-Whitney and multivariate ANOVA. The analysis by the craniometric method showed that gender influenced (p <0.05) in all measurements, more in men than women. There was no significant difference in the mastoid process position between the ethnic groups and genders (p> 0.05), but there was prevalence of male over female in the measurements and the Po-Ms - Po (p <0.05). ANOVA and Tukey test showed that gender influenced the width of the foramen magnum, and the male (30.3 ± 0.20) higher than the female (29.4 ± 0.23) but not the length (p <0.05). The three differents methods show mophometric difference between sexes for the craniofacial characteristics of the Brazilian. Therefore, together with other anthropological techniques can help to determine the gender of unknown individuals and be used in assotiation with medical expertise and odontolegais. Ver menos
