Summary

Facial asymmetry in adult males is typically fluctuating, with the most significant variations observed in the cranial vault, not a specific side of the face. These differences are individual, not indicative of a dominant facial side.

Area of Science:

  • Anthropometry
  • Human Anatomy
  • Medical Imaging

Background:

  • Facial symmetry is a key aspect of human aesthetics and development.
  • Understanding the patterns of facial asymmetry is crucial for clinical and research applications.
  • Previous studies have explored various facial regions, but comprehensive analysis across the entire face is needed.

Purpose of the Study:

  • To quantitatively analyze facial asymmetry in adult males using frontal plane analysis.
  • To determine the distribution and magnitude of asymmetries across different facial regions (upper face, mandible, cranial vault).
  • To ascertain if a predominant side exists in facial asymmetry.

Main Methods:

  • Assessment of cranial anteroposterior X-ray films.
  • Analysis of facial asymmetries in the frontal plane.
  • Inclusion of 38 normal adult males in the study cohort.

Main Results:

  • Facial asymmetries were found to be of a fluctuating type.
  • Slightest asymmetries were noted in the upper face.
  • Mandibular characteristics showed moderate deviations, while the cranial vault exhibited the most marked asymmetries.
  • No significant predominance of asymmetry was observed between the left and right sides of the face.

Conclusions:

  • Facial asymmetries in adult males are characterized by fluctuating patterns rather than consistent directional bias.
  • The magnitude of asymmetry varies across facial regions, being most pronounced in the cranial vault.
  • Observed facial asymmetries are primarily of an individual character, reflecting unique anatomical variations.
