Inverted Horseshoe Osteotomy for Vertical Chin Reduction and Masculinization Procedure With Individual Mandibular...

Area of Science:

• Orthognathic surgery
• Facial plastic surgery
• Gender-affirming surgery

Background:

• Sliding genioplasty corrects bone discrepancies and asymmetries in orthognathic and facial plastic surgery.
• Chin narrowing is used in male-to-female gender-affirming surgery for a triangular lower face.
• Female-to-male transitions and cisgender male aesthetic surgery increasingly require lower face masculinization.

Purpose of the Study:

• To present a protocol for lower face masculinization.
• To describe a modified chin osteotomy technique.
• To explore its use with custom mandibular angle implants.

Main Methods:

• Modified chin osteotomy protocol.
• Surgical technique for lower face masculinization.
• Potential combination with custom mandibular angle implants.

Main Results:

• The protocol facilitates lower face masculinization.
• The modified osteotomy allows for a squared jaw and stronger chin.
• This technique addresses the needs of female-to-male and cisgender male patients.

Conclusions:

• The modified chin osteotomy is a viable technique for lower face masculinization.
• This approach can enhance masculine facial aesthetics.
• It offers a surgical solution for specific gender-affirming and aesthetic goals.
