Population comparison of facial soft tissue thickness

Area of Science:

• Anthropology
• Forensic Science
• Medical Imaging

Background:

• Facial soft tissue thickness is a key parameter in various fields, including forensic anthropology and plastic surgery.
• Previous research has measured soft tissue depth across diverse global populations, yet comparative analyses with standardized criteria are limited.

Purpose of the Study:

• To systematically compare facial soft tissue thickness measurements from existing literature with a specific study group.
• To identify potential population-specific variations in facial soft tissue depth among adult females.

Main Methods:

• A meta-analysis was conducted, including 32 studies meeting specific criteria: adult females (18-30 years), normal Body Mass Index (BMI), and >10 participants per study.
• Data from selected studies and a contemporary study group were analyzed using Kruskal-Wallis test in RStudio.
• Statistical significance was assessed to determine variations in soft tissue thickness.

Main Results:

• The Kruskal-Wallis test did not reveal statistically significant differences in facial soft tissue thickness when comparing the included studies and populations.
• This finding suggests that variations in soft tissue depth might not be a primary differentiator between the studied populations.

Conclusions:

• Facial soft tissue thickness does not appear to vary significantly across different populations under the specified controlled conditions (age, BMI, sex).
• The study suggests that skeletal morphology, specifically bony mass, may hold greater significance in distinguishing individuals and populations for facial identification purposes.
