Protruding or concealed: Defining ideal cranioauricular angle via a morphometric analysis in Asians

Area of Science:

• Plastic Surgery
• Aesthetic Medicine
• Facial Aesthetics

Background:

• The frontal ear appearance is increasingly important in Asian facial aesthetics.
• A standardized ideal cranioauricular angle is currently lacking.
• This study addresses the need for consensus on optimal ear aesthetics.

Purpose of the Study:

• To investigate the ideal cranioauricular angle preferred by the Asian population.
• To establish aesthetic guidelines for otoplasty in Asian individuals.
• To correlate cranioauricular angle with facial proportions.

Main Methods:

• A questionnaire-based survey was conducted among a diverse Asian population.
• Participants evaluated digitally manipulated images of ears at various cranioauricular angles.
• Demographic data and interest in otoplasty were recorded.

Main Results:

• A 30-degree cranioauricular angle was overwhelmingly preferred across genders and face shapes (P<0.0001).
• This angle corresponds to specific facial width ratios, indicating aesthetic harmony.
• Ideal angles ranged from 30 to 40 degrees, with variations based on demographics.

Conclusions:

• A 30-degree cranioauricular angle is the preferred aesthetic standard for Asian ears.
• These findings provide crucial data for surgical planning in cosmetic otoplasty.
• Understanding ideal angles enhances patient satisfaction and surgical outcomes.
