Correcting the Broad, Flat and Short Chin Using Modified M-genioplasty

Area of Science:

• Plastic Surgery
• Craniofacial Surgery
• Aesthetic Surgery

Background:

• Existing genioplasty techniques often fail to satisfy patients with broad and short chins.
• A need exists for improved surgical methods to correct these specific chin deformities.

Purpose of the Study:

• To evaluate the clinical outcomes of a modified M-shaped genioplasty for correcting broad, flat, and short chin deformities.
• To assess patient satisfaction and aesthetic results following this specific surgical intervention.

Main Methods:

• A cohort of 38 patients with broad, flat, and short chins underwent modified M-shaped genioplasty between January 2019 and December 2021.
• Individualized preoperative planning guided the narrowing and vertical elongation genioplasty.
• Patient-reported outcomes were assessed using the FACE-Q questionnaire preoperatively and 3 months postoperatively.

Main Results:

• Significant vertical lengthening (average 3.02 mm) and horizontal narrowing (average 5.6 mm) of the chin were achieved.
• Patient satisfaction with chin appearance significantly increased, with FACE-Q scores rising from 35.34 to 72.95.
• No severe complications were reported during the 3-24 month postoperative follow-up period.

Conclusions:

• Modified M-shaped genioplasty is a reliable technique for correcting short, flat, and broad chin deformities.
• The procedure preserves critical bone structures and muscular attachments, allowing for rapid bone segment repositioning.
• This method yields esthetically satisfying results by addressing chin dimensions in three dimensions.
