What Is a Wide or Square Jaw?

A wide or square jawline occurs when the mandibular angle (the lower jawbone) is naturally broad or thick, giving the face a boxy, masculine appearance. This is a common concern for individuals who prefer a slimmer, more delicate V-line facial contour.

Key features of a wide jaw include:

• A square, broad lower face
• A bulky or heavy jawline
• Prominent angles at the sides of the jaw
• A facial shape that appears short and wide
• Difficulty achieving a slim, tapered look with makeup or hairstyles

What Is Jaw Reduction Surgery?

Jaw Reduction Surgery is a bone contouring procedure that removes or reshapes the mandibular angle and lower jaw to create a slimmer, more defined V-line profile.

At Seoul Cheil Plastic Surgery, jaw reduction is performed with precision and artistry for natural-looking, scar-free results. The procedure involves:

• Making a hidden incision inside the mouth for no visible scars
• Trimming or reshaping the mandibular angle and jawbone
• Smoothing and blending the bone for a soft, tapered contour
• Surgery time: Approximately 2–3 hours under general anesthesia
• Often combined with chin surgery (genioplasty) or masseter muscle reduction for a complete V-line transformation

Why Combine With Other Procedures?

Jaw width is just one part of the overall facial contour. For optimal balance and harmony, jaw reduction is often combined with:

• Chin reshaping (genioplasty) for ideal projection and shape
• Buccal fat removal for cheek slimming
• Cheekbone reduction for facial width balance
• Fat grafting to restore soft tissue volume where needed

This holistic approach ensures a natural, proportional result that enhances your unique beauty.

Key Characteristics of a Face That May Benefit From Jaw Reduction Surgery

• A square, wide, or angular jawline
• A heavy, masculine lower face
• A face that appears short and broad
• Difficulty achieving a V-line silhouette
• A desire for a softer, more feminine contour

Can Botox Replace Jaw Reduction Surgery?

Botox can help slim the masseter muscle for a temporary reduction in jaw bulk, but it:

• Cannot reduce bone width
• Requires repeat treatments every 4–6 months
• Is not a permanent solution for true bony prominence

For permanent, structural results, jaw reduction surgery is the only effective option.
