What Is a Prominent Anterior Mandible?

A prominent anterior mandible occurs when the front portion of the lower jaw (chin and jawline) appears excessively wide, bulky, or square-shaped. This condition often leads to a heavy lower face, a masculine appearance, or an unbalanced facial profile that lacks the desired slim and tapered V-line shape.

Key features of a prominent anterior mandible include:

• A wide, square chin when viewed from the front
• A bulky jawline in the lower third of the face
• A heavy, masculine lower face appearance
• Lack of definition or a blurry transition between the chin and jaw
• A face that looks shorter and broader than desired

What Is Anterior Mandible Reduction Surgery?

Anterior Mandible Reduction Surgery is a bone contouring procedure that refines and slims the front portion of the mandible (the lower jaw), including the chin and adjacent jawline.

At Seoul Cheil Plastic Surgery, this procedure is performed by experienced bone surgeons who focus on natural-looking results and facial harmony. The surgery typically involves:

• Making a hidden incision inside the mouth for no visible scars
• Trimming and reshaping the anterior mandible bone to create a slimmer, more tapered chin and jawline
• Smoothing the bone contours for a seamless transition from the chin to the lower jaw
• Surgery time: Approximately 1.5–2 hours under general anesthesia
• Often combined with chin (genioplasty) or square jaw reduction for a complete V-line effect

Why Combine With Other Facial Contouring Procedures?

A prominent anterior mandible often affects the overall facial shape. To achieve a harmonious result, anterior mandible reduction is frequently combined with:

• Square jaw reduction (mandibular angle reduction) for a slimmer jawline
• Chin reshaping (genioplasty) for an ideal chin size and projection
• Cheekbone reduction (malarplasty) for balanced facial width
• Fat grafting to restore natural volume and smooth contours

This comprehensive approach ensures a proportionate, elegant, and natural-looking outcome.

Key Characteristics of a Prominent Anterior Mandible

• A broad, wide chin
• Square, masculine lower face
• Heavy or boxy jawline
• Short, wide face shape
• A face that lacks softness or tapering
• Difficulty achieving a slim, feminine V-line appearance

Can Fillers or Botox Reduce a Prominent Mandible?

Fillers add volume and are not suitable for reducing bone.
Botox can temporarily slim the masseter muscle (for a bulky jawline caused by muscle), but it cannot reshape bone.

For true bony width issues, anterior mandible reduction surgery is the only permanent solution.
