Abstract
Objectives: To establish the correlation between orbital measurements and the height of individuals of a Brazilian population for human identification and height estimation. Materials and Methods: The sample consisted of 100 patients of both sexes, from Brazil Northeast, who sought the radiology service of the Oswaldo Cruz University Hospital to undergo facial CT for other purposes. Sex and stature of each subject were obtained on this occasion. After data collection, the craniometric points were determined and tomographic measurements were taken, correlating the findings with the variables studied. Results: Sixty-four (64.3%) of the participants were male and 36 (35.7%) were female. Stature was significantly greater in men than in women. The two variables had positive coefficients and were significant (p < 0.001), with female sex being used as the reference. The coefficient of determination was 0.435, indicating a reasonable fit of the model to the data. The orbit measurements can be accurate on estimating male and female stature in 83%. Conclusion: The orbit is an effective parameter for the estimation of stature from images of bone remains for human identification, in which linear orbital measurements can be correlated with anthropometric data (sex, and stature). An equation was proposed for estimating a subject’s stature in the population studied.
Highlights
The orbit is an effective parameter for the estimation of stature from images of bone remains for human identification, in which linear orbital measurements can be correlated with anthropometric data
Significant differences (p < 0.05) between sexes were observed for MF-EC and EC-OF on the right side and for MF-EC on the left side, with the mean values being higher in men
Given the importance of stature for the area of human identification and the paucity of studies correlating the anthropometric measurements of height with orbital dimensions, this study aimed to develop a new tool that could facilitate dental/medical work examiners during the identification of cadavers in a Brazilian population
Summary
Some height estimation methods using long bones, cranium, and spinal vertebrae have been developed and applied to different populations. The main problem encountered is that the methods are developed for a given population and cannot be applied to another with different races and miscegenation (Belmonte et al, 2011). In countries like Brazil, which is characterized by widespread racial miscegenation, this evaluation is difficult because of the lack of standards and methods used in this population for human identification. To minimize such problems, population studies are necessary to obtain in-depth knowledge of the variables that affect the population studied
