Facial approximation: Soft tissue thickness values for Caucasian males using cone beam computer tomography

Area of Science:

• Forensic Anthropology
• Medical Imaging

Background:

• Forensic identification of skeletal remains is crucial when other evidence is lacking.
• Anthropological analysis estimates age, sex, and race, narrowing identity possibilities.
• Facial reconstruction aids recognition and can be supported by comparative analysis with provided data.

Purpose of the Study:

• To measure soft tissue thickness (STT) from 12 bone landmarks in Caucasian males.
• To provide data for accurate facial reconstruction and skeletal identity assignment.
• To assess the reliability of cone beam CT (CBCT) for obtaining STT data.

Main Methods:

• Analysis of cone beam CT (CBCT) scans from 30 Caucasian males.
• Measurement of soft tissue thickness (STT) at 12 specific bone landmarks.
• Descriptive statistics and comparison with existing literature and databases.

Main Results:

• Average STT values were obtained for Caucasian males at 12 defined bone landmarks.
• CBCT scans provided detailed data for facial reconstruction.
• Measurements were repeated to ensure reliability.

Conclusions:

• The obtained STT data can significantly aid forensic facial reconstruction.
• CBCT is a valuable, low-radiation tool for head and neck imaging in forensic applications.
• This study contributes to improving the accuracy of facial approximation in forensic identification.
