“…This difference was also noted for subjects with different skeletal malocclusions. 5,18,19 In general, women's skin lacks collagen synthesis and facilitates synthesis of hyaluronic acid because of estrogen. In contrast, men tend to have thicker skin because testosterone facilitates collagen synthesis.…”

“… found significant differences in facial soft tissue thickness among three skeletal classes at labrale superius, stomion, and labiomentale in Turkish subjects and Utsuno et al. found significant differences in soft tissue thickness at subnasale, labrale superious, stomion, labiomentale, and pogonion in Japanese females. The current study showed that facial soft tissue thickness varied significantly among different skeletal classes at glabella, labrale superius, stomion, and labiomentale in males and at labrale superius, labrale inferius, labiomentale, and pogonion in females.…”

“…This discrepancy in the results of the two studies conducted on a sample from the same population may be due to the lack of controlling for the vertical growth pattern in the second study which is a known confounding factor. Utsuno et al (18) conducted a study on Japanese adult subjects and showed that the sex-based differences in facial soft tissue thickness were statistically significant at five points in subjects with skeletal classes I and III. However, the current study conducted on Pakistani subjects reports a greater sexual dimorphism in class II and class III subjects, in which a significant difference in facial soft tissue thickness was found at six points in each group.…”

Different facial reconstruction methods rely on the average facial soft tissue thickness values provided in previous studies. Facial soft tissue thickness is influenced by the age, sex, and ethnicity of the individual. The aim of the present study was to determine facial soft tissue thickness of adult Pakistani subjects with different facial morphology. A total of 166 subjects were categorized into three skeletal classes (based on convex, straight, or concave facial profile) employing the classification system used in orthodontics. Facial soft tissue thickness was determined at ten midline points on lateral cephalograms. Significant differences in facial soft tissue thickness were present at glabella, labrale superius, stomion, and labiomentale in males and at labrale superius, labrale inferius, labiomentale, and pogonion in females among different skeletal classes. The current study suggests that the skull morphology-related variations in facial soft tissue thickness should be considered during facial reconstruction to achieve accurate results.

Forensic facial reconstruction may be the final option available to draw public attention in cases where the identity of an individual cannot be established by standard identification methods. Two fundamental components of all forensic facial reconstruction techniques are cranial morphology and soft tissue depth databases. The purpose of this study was to extend such databases by providing a complete set of accurate facial soft tissue thickness measurements, acquired from a contemporary adult population from Germany. The material for the study consisted of 320 (160 male, 160 female) anonymised multi-slice computerised tomography (MSCT) scans of individuals drawn from a German population. In Amira®, 3D models of the surfaces of the skull and the facial skin were semi-automatically segmented using calculated thresholds and surface extraction algorithms. Facial soft tissue depth was measured at 10 midline and 28 bilateral anatomical landmarks. The analysis of facial soft tissue thickness versus BMI, sex and age indicated that, at a number of the landmarks, facial soft tissue depth is significantly (p < 0.05) influenced by all three biometric variables. Facial soft tissue thickness increased with increasing BMI. The differences between males and females were statistically significant (p < 0.05) for almost all anatomical landmarks with the exception of a few in the region of the nasal root and orbitals. Asymmetry was noted at over half of the bilateral landmarks. The differences between the results from this sample and those obtained from comparable databases contradict the hypothesis that population specificity significantly influences facial soft tissue thickness.
