Análisis cefalométrico mediante radiografías laterales de cráneo en la determinación del género humano usando el dimorfismo sexual del seno maxilar

The determination of the human race in forensic sciences is one of the main objectives to begin with an investigation; where technology and its advances are a tool to obtain results by using radiographic and morphometric methods applied to the maxillary and frontal sinus; dimensions in the difference of both the shape, size between men and women (sexual dimorphism). The objective of the present study was to analyze lateral skull radiographs, using the sexual dimorphism of the maximal sinus and the frontal sinus by means of a cephalometric analysis, for the determination of the human race; and its application in forensic identification processes. A total of 52 lateral skull radiographs were obtained: 26 men and 26 women respectively, to which an experimental investigation was applied; the height, width and area of the maximum sinus were analyzed as well as the frontal sinus with a cephalometric analysis in the digital program (CEFAX); The technique that was used was the observation and the instrument that was the observation sheet, the corresponding parametric and non-parametric tests, a principal component analysis for predictive models and a discriminant function. As results, it was obtained that 23 of the 26 samples were correctly identified as women with specificity of 88.5% and 22 of the 26 samples were identified as men with sensitivity of 84.6% and of all the cases grouped, 86.5% were correctly classified. With the results of the study it was concluded that it is possible to determine gender using a cephalometric analysis on lateral skull radiographs
