What Is a Bulky or Square Jawline?

A bulky or wide jawline can make the lower face appear boxy, masculine, or heavy—especially when the outer layer of the jawbone (cortical bone) is naturally thick. This excess bone can create a blunt, angular appearance that some patients wish to refine for a slimmer, more feminine V-line.

Key characteristics of a bulky jawline include:

• A square-shaped lower face
• Jawline that appears broad from the front
• A heavy, masculine look even in slim individuals
• Lack of a defined, delicate facial contour
• Difficulty achieving a smooth, tapered V-line with makeup or hairstyles

What Is Mandibular Cortical Bone Shaving?

Mandibular Cortical Bone Shaving is a bone contouring procedure that removes the outermost layer (cortex) of the jawbone to reduce width and bulk. This technique allows for a natural, subtle refinement without altering the core structure of the mandible.

At Seoul Cheil Plastic Surgery, the procedure is performed with precision and artistry to achieve a slimmer, more elegant jawline. The process involves:

• Making a hidden incision inside the mouth for a scar-free result
• Carefully shaving the outer cortical layer of the mandible
• Refining the jawline for a narrower, softer appearance
• Surgery time: Approximately 1.5–2 hours under general anesthesia
• Often combined with mandible angle reduction or chin reshaping for a complete V-line transformation

Why Combine With Other Procedures?

For a truly balanced and harmonious result, mandibular cortical bone shaving is often combined with:

• Mandible angle reduction for a sharper, more defined jawline
• Chin surgery (genioplasty) to refine projection and shape
• Cheekbone reduction (malarplasty) for facial width balance
• Fat grafting to restore soft tissue volume where needed

This holistic approach ensures a natural-looking, proportional result that complements the entire face.

Key Characteristics of a Face That May Benefit From Mandibular Cortical Bone Shaving

• A broad, wide lower face
• Jawline that appears blunt or thick
• A square, masculine jawline
• Lack of smooth, feminine facial lines
• A heavy appearance despite a slim figure

Can Fillers, Botox, or Fat Dissolving Injections Replace Bone Shaving?

No.

• Fillers add volume—not reduce bone width
• Botox can relax the masseter muscles, but won’t reshape the bone
• Fat dissolving injections target fat, not bone

For true bone structure refinement, mandibular cortical bone shaving is the only effective solution.
