“…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. Statistically significant differences have been reported in facial tissue depths of different races.…”

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.

“…It has been established that gender has a significant effect on the facial STTs at glabella [10,30], nasal region [10,15,19,22,31], lower part of the nose area [2], mouth [2,5,13,22,31], chin [5,13], orbital region [13,15,31], cheek region [13,19] as well as at the landmarks on the mandible [10,13,19,22,30] and maxilla [10,15,19,30].…”

“…STT data have been obtained on X-ray images as well, allowing these measurements to be taken in vivo [1,11,14]. However, at present, such data have been collected from living individuals using ultrasound [1,4,6,13,33], magnetic resonance imaging [23], and computed tomography (CT), including data from multislice CT [3,10,15,20], spiral CT [2,9,19, 31] and cone-beam CT [16,22].…”

“…Thus, there are many datasets available for various population groups from Europe [5,6,15,19,31], Asia [2,9,16,18,23,29], North America [4,21], South America [22,30], Africa [1,3,13,20], and Australia [8,24,28]. For some of the population groups, the presence of significant interpopulation differences in the facial soft tissues has been established in the comparison with other close or distant populations [2,3,13,20].…”

Facial soft tissue thicknesses in Bulgarian adults: relation to sex, body mass index and bilateral asymmetry

The aim of the study is to measure the facial soft tissue thicknesses (STTs) in Bulgarians, to evaluate the relation of the STTs to the nutritional status, sex and bilateral asymmetry, and to examine the correlations between the separate STTs as well as between the STTs and body weight, height, and body mass index (BMI). In the present study, the facial STTs were measured on computed tomography scans of the head of Bulgarian adults. The STTs were measured at 7 midline and 9 bilateral landmarks. The measurements were performed in the free software InVesalius in the axial and sagittal planes. The mean, standard deviation, minimum and maximum values, median and coefficient of variation were reported for the STT at each landmark according to the sex and BMI category. The BMI, sex and bilateral differences were assessed for statistical significance. Pearson correlation analysis was applied to assess the strength and direction of the relationships between the STTs and body height, weight and BMI, as well as between separate STTs. The facial soft tissues in Bulgarian adults changed in accordance with the nutritional status of the individual and in both sexes all STTs augmented with the increasing BMI. For both normal and overweight BMI categories, males had more soft tissue at the majority of facial points than females, as the only exceptions were observed in the cheek zone, where STTs were thicker in females. Significant bilateral differences were observed in either sex and BMI category. Stronger correlations were established for the STTs in the jaw region and between the cheek and jaw soft tissues. Besides, the correlations between the homologous bilateral landmarks were among the strongest ones.
