“…Hwang et al [27] prepared a database of soft tissue thickness for Korean adults and reported that mandibular region tissue thickness showed greater bilateral cephalometry which can be effectively used for forensic craniofacial reconstructions. Sfroza et al [28] provided sexand age-related soft tissue dimensions of orbital region in a Sudanese population to be used for forensic purposes like evaluations of traumas, craniofacial alterations, facial reconstructions, ageing of living and dead people. Guyomarch et al [29] investigated variability in facial soft tissue depths of French adults collected from 37 landmarks on 500 CT (computed tomography) scans and found negligible variations with sex, though corpulence was found significantly correlated with FSTT.…”

Craniofacial identification is a technique for prediction and recreation of life-like appearances of an individual, recreated onto an unknown skull on the basis of intricate relationship existing between underlying bony contour and the overlying soft tissues, muscles and skin. Tissue thicknesses in different population have wide variations due to disparities in nutritional, environmental or genetical factors. The physical health, nutritional status and disease activity of an individual have significant and detectable influences on both the complex anatomy of facial skeleton as well as soft tissue depths. Present study was conducted on 50 MRI and 53 CT normal scans of 64 male and 39 female Northwest Indian adult subjects who reported to radio-imaging diagnostic centres for some clinical and therapeutic reasons. Soft-tissue thickness was estimated at 33 craniofacial landmarks on both MRI and CT scans using OsiriX v 6.0.2 64 bit software and Digital Imaging and Communications in Medicine (DICOM) format images. MRI scans were found comparatively better and more reliable mean of estimating tissue depths and for sex estimations. Statistically significant sex differences were noticed in tissue depths at various craniofacial landmarks. The endocanthion was found the best sex discriminating variable from both types of scans. MRI and CT scan estimated tissue thicknesses could identify sex of 96% and 85%, subjects, respectively. Secular increase in tissue depths was observed to support the increased trend of obesity in present day population of the area when compared with similar studies conducted few decades earlier. Present study results can be a valuable adjunct for forensic anthropological facial reconstructions and experts of diverse medical disciplines.

“…In particular, the eyes and the orbital region play a predominant role in the evaluation and recognition of the craniofacial complex 5,10,11 and are among those facial areas that are considered to be at the center of esthetic evaluation. 3,5,6,8,[12][13][14] According to the current theories of evolutionary psychology, the esthetic assessment of adult faces depends on various combinations of averageness, symmetry, neoteny (babyness) and youthfulness, and sexual dimorphism.…”

Objective: To identify esthetic characteristics of the orbital soft tissues of attractive Italian adult women and men. Materials and Methods: Three-dimensional computerized digitizers were used to collect the coordinates of facial landmarks in 199 healthy, normal subjects aged 18 to 30 years (71 women, 128 men; mean age, 22 years) and in 126 coetaneous attractive subjects (92 women, 34 men; mean age, 20 years) selected during beauty competitions. From the landmarks, six linear distances, two ratios, six angles, and two areas were calculated. Attractive subjects were compared with normal ones by computing z-scores. Results: Intercanthal width was reduced while eye fissure lengths were increased in both genders. Orbital heights (os-or) were increased only in attractive women, with a significant gender-related difference. The inclinations of the eye fissure were increased in attractive subjects, while the inclinations of the orbit were reduced. For several of the analyzed measurements, similar patterns of z-scores were observed for attractive men and women (r 5 .883). Conclusion: Attractive women and men had several specific esthetic characteristics in their orbital soft tissues; esthetic reference values can be used to determine optimal goals in surgical treatment.

Objective: To compare the proportion and linear measurement indexes between Brazilian and Peruvian population through 3D stereophotogrammetry and to stablish the face profile of these two Latin American populations. Material and Methods: 40 volunteers (Brazilian n = 21 -10 males and 11 females; Peruvian n = 19 -8 males and 11 females) aged between 18 and 40 years (mean of 28.7 ± 9.1) had landmarks marked on the face. Then, 3D images were obtained (VECTRA M3) and the indexes of proportion and linear measurement (face, nose, and lips) were calculated. The data were statistically analyzed by One-Way ANOVA (p < 0.05). Results: The proportion indexes did not reveal marked differences either between the studied populations or genders (p > 0.05). The following linear measurements showed intergroup statistically significant differences: face width and height, nose width and height, upper facial height, mouth width, protrusion of the nose tip (p < 0.05). The Brazilian females showed the smallest significant differences. Conclusions: Despite the different ethnic compositions, the Brazilian and Peruvian populations did not differ regarding the proportions of the face, nose, and lips. The differences observed in Brazilian females may be related to gender and/ or to the Caucasian heritage of the Brazilian sample. ReSumoObjetivo: Comparar índices de proporção e medidas lineares da face entre amostras de populações brasileiras e peruanas por meio da estereofotogrametria 3D, a fim de estabelecer o perfil facial destas duas populações latino-americanas. Material e Métodos: 40 voluntários (21 brasileiros -10 homens e 11 mulheres; 19 peruanos -8 homens e 11 mulheres) com idade entre 18 e 40 anos (média de 28,7 ± 9,1) tiveram pontos de referência marcados na face, foram então obtidas imagens 3D (VECTRA M3) e calculados índices de proporção e medidas lineares da face, nariz e lábios. Os dados foram analisados estatisticamente por meio de ANOVA One Way (p < 0,05). Resultados: Os índices de proporção não revelaram grandes diferenças entre as populações analisadas ou entre gêneros (p > 0,05). As medidas lineares que apresentaram diferença significativa na análise intergrupos foram: largura e altura da face e do nariz, altura da face superior, largura da boca e protrusão da ponta do nariz (p < 0,05), sendo que as brasileiras apresentaram as diferenças mais significativas em relação aos demais grupos, com medidas faciais menores. Conclusões: As populações brasileiras e peruanas, apesar das diferentes composições étnicas, não diferem quanto às proporções de face, nariz e lábios. As diferenças observadas no grupo de brasileiras podem estar relacionadas ao gênero e/ou à maior descendência caucasiana da amostra quando comparada à população peruana.
