The study on facial soft tissue thickness using Han population in Xinjiang

Area of Science:

• Anthropology
• Forensic Science
• Cosmetic Research

Background:

• Facial soft tissue thickness is vital for facial restoration but varies significantly by demographics.
• Few studies consider nutritional status, and research on Xinjiang populations is scarce.
• Understanding these variations is crucial for accurate forensic and anthropological applications.

Purpose of the Study:

• To investigate facial soft tissue adaptability to hard tissue in young Han adults from Xinjiang, China.
• To analyze variations based on gender, skeletal class, and body mass index (BMI).
• To provide data for forensic facial reconstruction and identification.

Main Methods:

• Analysis of lateral cephalometric radiographs from 256 adults (aged 18-26).
• Measurements focused on facial soft tissue thickness.
• Data analyzed for differences across gender, skeletal class, and BMI groups.

Main Results:

• Significant differences in soft tissue thickness were observed between genders and skeletal classes.
• Gender-specific differences in soft tissue thickness were noted at key facial landmarks across BMI groups.
• The thinnest craniofacial soft tissues were found at the rhinion, and the thickest in the lip regions.

Conclusions:

• Nutritional status (BMI) is an important factor influencing facial soft tissue thickness.
• The study provides valuable anthropometric data for the Xinjiang Han population.
• Findings support improved accuracy in forensic facial reconstruction and identification.
