“…The result has proven that both length and width of the occipital condyle have higher mean value in males, which agrees with other anthropological researches of sex determination by craniometrical variation (Duric et al, 2005;Günay & Altinkök, 2000;Machado et al;Kemkes & Gobel, 2006;Kimmerle et al, 2008;Kranioti et al, 2008;Monticelli & Graw, 2008;Naikmasur et al).…”

SUMMARY:In human identification for forensic purposes the sex is one of the most important and first features to be assessed in each case. Baudoin condylar index is a sex determination method based on measurements of length and width of the occipital condyle. The aim of this research was to apply the Baudoin condylar index for sex determination, and evaluate its reliability. The sample was composed of 100 Brazilian human skulls, 50 male and 50 female from São Gonçalo cemetery, City of Cuiabá, Brazil. The measurement values were statistically analyzed in order to compare the matching rate for each sex, each side, as well as the overall average. The results showed that the overall percentage of success in applying the Baudoin index was 44.83% to males, and 51.93% to females, amounting to 47.5% matching. The accuracy of the Baudoin index to sex determination was quite low for this Brazilian sample, the reason why this method should be disregarded as a criterion to sexing skulls in a forensic context.

“…S-I did not differ with sex because the zygomatic bone may be more prominent in males than in females, and so IOM will project about 1 mm more in males than in females, which will also be the case for SOM. The hypothesis of sexual dimorphism in the zygomatic bone is consistent with previous studies [30]. Consequently, the positions of the eyeballs themselves in the orbit do not differ between the sexes, but the eyeballs of males appear more regressed in the orbit than in females because the orbit is deeper due to the prominence of SOM and IOM (Fig.…”

Three-dimensional and topographic relationships between the orbital margins with reference to assessment of eyeball protrusion

This study investigated the topographic relationships among the eyeball and four orbital margins with the aim of identifying the correlation between orbital geometry and eyeball protrusion in Koreans. Three-dimensional (3D) volume rendering of the face was performed using serial computed-tomography images of 141 Koreans, and several landmarks on the bony orbit and the cornea were directly marked on the 3D volumes. The anterior-posterior distances from the apex of the cornea to each orbital margin and between the orbital margins were measured in both eyes. The distances from the apex of the cornea to the superior, medial, inferior, and lateral orbital margins were 5.8, 5.8, 12.0, and 17.9 mm, respectively. Differences between sides were observed in all of the orbital margins, and the distances from the apex of the cornea to the superior and inferior orbital margins were significantly greater in females than in males. The anterior-posterior distance between the superior and inferior orbital margins did not differ significantly between males (6.3 mm) and females (6.2 mm). The data obtained in this study will be useful when developing practical guidelines applicable to forensic facial reconstruction and orbitofacial surgeries.

“…L'os zygomatique possède selon nos résultats un fort dimorphisme sexuel de conformation mais utilisé en métrique classique, il ne permet généralement pas d'effectuer une diagnose sexuelle satisfaisante [68]. Cet échec peut être en partie attribué aux biais liés à la taille.…”

Dimorphisme sexuel du crâne de sujets identifiés (collection Olivier, MNHN, Paris) : évaluation par morphométrie géométrique Cranial sexual dimorphism of identified subjects (collection Olivier, MNHN, Paris): an evaluation by geometric morphometrics P. Guyomarc'h · J. Bruzek Reçu le 25 mars 2009 ; accepté le 5 mai 2010 © Société d'anthropologie de Paris et Springer-Verlag France 2010Résumé La diagnose sexuelle à partir du squelette se partage entre les méthodes visuelles, chargées d'une grande subjectivité et nécessitant un apprentissage, et les méthodes métriques (fonctions discriminantes) qui sont spécifiques aux populations à partir desquelles elles ont été élaborées. La principale limite de ces dernières méthodes en termes de reproductibilité est incarnée par le facteur taille, connu pour être variable d'une population à l'autre. Les récents développements de la morphométrie géométrique ouvrent de nouvelles voies de recherche. Cette étude évalue le degré de dimorphisme sexuel du crâne d'une série de 50 squelettes identifiés (25 hommes et 25 femmes issus de la collection Olivier, MNHN, Paris) par le biais de la morphométrie géométrique. Cette technique autorise une séparation de la taille globale et de la conformation des crânes. Les variations de taille et de conformation ainsi identifiées sont alors statistiquement étudiées et interprétées. Notre échantillon révèle un fort dimorphisme sexuel de taille et un dimorphisme sexuel de conformation plus subtil, notamment dans la région faciale de nos individus. Ces différences entre hommes et femmes se concentrent sur l'os zygomatique, le temporal et la cavité nasale ; elles sont en partie imputables à des phénomènes allométriques et biomécaniques. Les perspectives de tels résultats sont discutées en termes de potentiels pour l'élaboration de méthodes de détermination du sexe à partir du crâne plus fiables. Mots clés Morphométrie géométrique · Dimorphisme sexuel · Crâne · Collection OlivierAbstract The sexual diagnosis based on the skeleton can be performed with visual methods but they appear subjective and require training. Metric methods are also widely used (discriminant functions) but they are known to be specific to the population, which they have been created with. The utmost cause of reproducibility limits inherent to these methods remains the size variable. Recent developments in geometric morphometrics open new research ways. This study evaluates the degree of cranial sexual dimorphism in a 50 identified skeletons sample (25 males and 25 females from the Olivier collection, MNHN, Paris) using geometric morphometrics. These tools allow separating the global size from the cranial shape. The size and shape variables can thus be statistically studied and interpreted. Our sample reveals a strong size-related sexual dimorphism and a more subtle shape-related sexual dimorphism, especially in the face region. These differences between males and females are concentrated in the zygomatic bone, the temporal and the nasal aperture. They can be linked to allometry and ...
