RESUMO

laughters, serial killers committed by psychos, tries in hiding cadavers and road catastrophes with dozen of dead people do that dayly legal medical exams are not enough for the identification of the victims. The craniofacial bone structures, well known as preservation capacity, are, a lot of times, the only way to extract identity informations, that has in the sex determination, one of its key elements. The objectivity and the statistic method precision show advantages in relation from vizualizing the morphologic aspects for the sexual definition. However, the use of antropometric parameters, proceeding from foreign researches, for the brazilian sex diagnostic, is a error pass, because the osteometric dimensions are dependent of genetic-physiologic-cultural analysed group. The objetives from the present study were: to verify the sexual dimorphism existence by four linear skull measures in brazilian person, which age and sex known, with the utilization of simple equipments, as well as, analyse the statistic significance degree, intending to create a function to another samples and construct a computer program to build the amonts, giving practicity to the technique. The sample consisted in 130 skulls (50 female and 80 male), from the beggars part public cemetery of the cities Salvador, São Paulo and Araçatuba, with superior ages from 20 years old and know sex, which registers were given by the institutions that carne from the Legal Medical lnstitute that sent it. The measures­ - anterior nasal spine to anterior border external auditory meatus and glabella to anterior nasal spine - were seen by the precision caliper. While glabella to lambda and lambda to inferior mastoidal pole were collected with the Willis compass, both millimeters graduated. All the dimensions were statistically significant (p<0,05) for the sexual discrimination when submited the test t of Student. The discriminant analysis by stepwise, permited the elaboration of logistic regression, from the distances: anterior nasal spine to anterior border external auditory meatus, glabella to anterior nasal spine and lambda to inferior mastoidal pole - to determine the probability of the skull pertinence to the female sex with 86,1% of confiability, result compatible the others studies of similar methodology. A computer program was crated to built the amounts and simplify the use of the technique
