Lower facial contouring surgery using a novel method: M-genioplasty

Area of Science:

• Plastic Surgery
• Oral and Maxillofacial Surgery
• Facial Aesthetic Surgery

Background:

• Facial contouring surgery, particularly mandibular contouring, is increasingly popular for achieving a slender appearance, especially in East Asia.
• Simultaneous mandibular angle resection with genioplasty is crucial for optimal results in chin narrowing procedures.
• T-genioplasty is a commonly performed technique in Korea for chin narrowing.

Purpose of the Study:

• To introduce and evaluate a novel surgical technique, M-genioplasty, for lower facial contouring.
• To assess the safety, reliability, and aesthetic outcomes of M-genioplasty combined with mandibular angle resection.
• To compare M-genioplasty with existing methods like T-genioplasty for chin narrowing and mandibular contouring.

Main Methods:

• M-genioplasty was performed on 36 patients between June 2013 and December 2017, combined with mandibular angle resection.
• The surgical technique involved oblique horizontal and vertical osteotomies, creating wedge-shaped bone segments.
• Resected bone segments were approximated centrally after rotation, and lateral mandibular bony step-offs were addressed during angle resection.

Main Results:

• All 36 patients demonstrated significant improvement in facial contour following M-genioplasty.
• The majority of patients reported high satisfaction with their aesthetic outcomes.
• No severe complications were observed during the postoperative follow-up period.

Conclusions:

• M-genioplasty allows for more extensive mandibular angle resection and achieves a more acute chin angle compared to T-genioplasty, without causing bone resorption.
• This technique offers advantages in creating a more slender and attractive lower facial appearance.
• M-genioplasty with mandibular angle resection is presented as a safer, more accurate, and reliable surgical option for lower facial contouring.
