Perceptions of a balanced facial profile

Area of Science:

• Dentistry
• Plastic Surgery
• Anthropometry

Background:

• Facial profile analysis is crucial in orthodontics and aesthetic surgery.
• Understanding the interplay of facial features (nose, lips, chin) influences perceived attractiveness.
• Previous research often focused on specific features or average parameters, lacking a comprehensive view of their combined aesthetic impact.

Purpose of the Study:

• To evaluate the aesthetic contribution of the nose, lips, and chin in determining a balanced facial profile.
• To identify preferred and least preferred combinations of these features in different facial profiles.
• To inform orthodontic treatment goals regarding facial aesthetics.

Main Methods:

• A survey was conducted using 545 dental and orthodontic professionals.
• Evaluated androgynous facial silhouettes with variations in nose, lip, and chin proportions.
• Silhouettes also featured altered facial angles and convexity, graded from most to least preferred.

Main Results:

• Males preferred straighter facial profiles, while females favored slightly convex profiles.
• Extremely recessive chins and excessively convex faces were consistently rated as least desirable.
• Increased lip protrusion was more acceptable with larger noses or chins in both sexes.

Conclusions:

• Orthodontic treatment should aim for harmonious facial balance rather than solely relying on average dental/skeletal metrics.
• Consideration of soft tissue changes in the nose, lips, and chin is vital for adolescent treatment planning.
• Aesthetic goals should be individualized, accounting for the complex interaction of facial features.
