What Is a Weak or Unbalanced Jawline?

A weak, short, or asymmetrical jawline can make the face appear soft, undefined, or unbalanced. Some people have a naturally small chin, while others may have an undefined mandibular angle—making the lower face look flat, receding, or lacking in structure.

Key characteristics of a weak jawline include:

• A short or recessed chin
• A flat or poorly defined mandibular angle
• Jawline blending into the neck without clear separation
• A “baby face” appearance in adults
• Facial imbalance, where the lower face appears underdeveloped compared to the upper face

What Is Chin Wing Osteotomy?

Chin Wing Osteotomy is an advanced jawline contouring surgery that redefines the entire lower face by moving and reshaping the chin, jawline, and mandibular angle.

Unlike traditional genioplasty, which only adjusts the chin, a chin wing osteotomy reshapes the entire jawline for a stronger, more defined, and naturally proportioned V-line appearance.

At Seoul Cheil Plastic Surgery, the procedure involves:

• Making hidden incisions inside the mouth for no visible scars
• Performing a precise bone cut along the lower border of the mandible
• Sliding the chin and jawline forward, downward, or reshaping the angle as needed
• Securing the new position with titanium plates and screws
• Surgery time: Approximately 3–4 hours under general anesthesia

Why Choose Chin Wing Osteotomy?

Chin Wing Osteotomy offers advantages that traditional genioplasty or implants cannot:
✅ Reshapes both the chin and the jawline for full-profile enhancement
✅ Improves facial proportions, definition, and symmetry
✅ Achieves a strong, balanced, and natural-looking jawline
✅ Avoids the risks of implants, such as shifting or unnatural feel
✅ Provides long-lasting, permanent results using your own bone

Why Combine With Other Procedures?

For a fully balanced and natural outcome, Chin Wing Osteotomy is often combined with:

• Square jaw (mandible angle) reduction for a slimmer lower face
• Cheekbone reduction (malarplasty) for facial width harmony
• Fat grafting to restore soft tissue volume
• Orthognathic (two-jaw) surgery if there are bite or skeletal alignment issues

This holistic approach ensures a harmonious, refined, and natural result.

Key Characteristics of a Face That May Benefit From Chin Wing Osteotomy

• A weak or short chin
• Lack of jawline definition
• A flat, blended chin-to-neck transition
• Underdeveloped or poorly defined mandibular angles
• Facial asymmetry or imbalance between the upper and lower face

Can Fillers or Fat Injections Replace Chin Wing Osteotomy?

Fillers and fat grafting can temporarily enhance volume, but they:
❌ Cannot reshape the bone structure
❌ Require maintenance every 6–12 months
❌ Do not achieve the same long-lasting, sculpted result

For permanent structural improvement, Chin Wing Osteotomy is the only effective solution.
