Area of Science:

  • Medical imaging and anthropometry
  • 3D facial analysis
  • Biometric measurement techniques

Background:

  • Accurate facial soft tissue measurement is crucial for various applications, including plastic surgery, orthodontics, and forensic science.
  • Traditional anthropometric methods can be subjective and time-consuming.
  • Advancements in 3D imaging technologies offer potential for more precise and objective facial measurements.

Purpose of the Study:

  • To evaluate and compare the accuracy and reproducibility of five different facial soft tissue measurement methods.
  • To assess the suitability of these methods for clinical practice and research.

Main Methods:

  • Five measurement methods were employed on 12 mannequin heads: Direct anthropometry, Digitizer, 3D CT, 3D scanner, and DI3D system.
  • 15 facial landmarks were marked, and 10 facial width, height, and depth measurements were taken twice by a single examiner.
  • Data were analyzed using SPSS, with statistical significance determined at p < 0.05.

Main Results:

  • All five methods demonstrated good accuracy and high reliability (reliability coefficient >0.92) with low technical error (<0.9 mm).
  • Direct anthropometry, 3D CT, digitizer, and 3D scanner yielded similar results, while the DI3D system showed slight variations.
  • While some specific measurements showed statistically significant differences between methods, the overall mean measurement error remained low (<0.7 mm) for all techniques.

Conclusions:

  • All evaluated 3D facial soft tissue analysis methods exhibit favorable accuracy and reproducibility.
  • These 3D techniques are suitable for application in clinical practice and research studies.
  • The findings support the use of advanced 3D imaging for precise facial anthropometric analysis.
