Clinical evaluation for chin augmentation: literature review and algorithm proposal.

Area of Science:

• Plastic Surgery
• Facial Aesthetics
• Anatomy

Background:

• Facial aesthetics rely on harmonious and symmetrical proportions.
• Existing methods for lower facial third analysis are complex.
• A simple, practical method for chin analysis is needed.

Purpose of the Study:

• To review soft tissue-based chin projection analysis methods.
• To highlight the advantages and disadvantages of each technique.
• To establish a basis for improved surgical planning.

Main Methods:

• Comprehensive literature review.
• PubMed database search.
• Analysis of established chin anthropometric methods.

Main Results:

• Reviewed methods include Gonzalles-Ulloa, Goode, Merrifield, Silver, Legan, Gibson & Calhoun, cervicomentual angle, and mentocervical angle.
• Each method offers unique insights into chin projection.
• Variability in approaches necessitates a standardized analysis.

Conclusions:

• Accurate facial proportion analysis is crucial for surgical planning and outcomes.
• Identifying facial disharmony guides procedural indications.
• An proposed algorithm simplifies chin augmentation surgery indications.
