Gender Facial Affirmation Surgery; Techniques for Feminizing the Chin.

Area of Science:

• Plastic Surgery
• Facial Feminization Surgery (FFS)

Background:

• The chin's shape and size significantly impact facial aesthetics, particularly the lower third.
• Osseous genioplasty is a key surgical procedure in FFS for modifying the chin.
• Patient desire for a "V" shaped lower face is a common goal in FFS.

Purpose of the Study:

• To review different osseous genioplasty techniques for facial feminization.
• To highlight the benefits of each genioplasty variation in achieving feminization goals.
• To emphasize critical surgical considerations for preventing complications.

Main Methods:

• Review of 1-piece genioplasty for size reduction and rounding.
• Analysis of 2-piece genioplasty for projection modification.
• Evaluation of 3-piece genioplasty for projection adjustment and chin narrowing.

Main Results:

• 1-piece genioplasty effectively reduces chin size and creates a rounder contour.
• 2-piece genioplasty allows for adjustment of chin projection while maintaining shape.
• 3-piece genioplasty offers projection control and beneficial narrowing for a "V" shaped jawline.

Conclusions:

• Variations of osseous genioplasty provide tailored approaches to chin feminization.
• 3-piece genioplasty is particularly effective for achieving a narrowed, "V" shaped lower face.
• Protecting the mental nerve and resuspending the mentalis muscle are vital for preventing nerve damage and lip ptosis.
