What is Square Jaw Reduction Surgery?

Square jaw reduction surgery, also known as mandibular angle reduction or jaw contouring, is a facial contouring procedure that softens a wide or angular lower face by reshaping the jawbone. This treatment is ideal for individuals with a prominent mandibular angle, often perceived as a "square" or masculine jawline. By trimming or shaving the outer edges of the lower jaw, the face achieves a more balanced, slender, and V-line appearance.

At CDU Plastic Surgery Clinic in Gangnam, Seoul, we specialize in square jaw reduction surgeries using advanced techniques, including intraoral (scarless) access and high-precision bone contouring. Our board-certified facial surgeons ensure safe procedures with natural-looking, symmetrical results tailored to each patient’s facial structure and goals.



Who is a Good Candidate for Square Jaw Reduction Surgery?

You may be a good candidate for square jaw reduction if you:

✔ Have a naturally wide or square lower face shape
✔ Feel your jawline appears overly prominent or masculine
✔ Desire a softer, more feminine or oval facial contour
✔ Are in good physical and mental health
✔ Have realistic expectations about the outcome

A personalized consultation at CDU Plastic Surgery Clinic will assess your bone structure, facial proportions, and aesthetic goals to recommend the best surgical plan—whether it be square jaw reduction alone or in combination with other facial contouring procedures like cheekbone reduction or genioplasty.

How is Square Jaw Reduction Surgery Performed?

1. Consultation & Evaluation

• Facial analysis using 3D imaging and X-rays to assess jawbone thickness and muscle structure
• Discussion of concerns—whether functional (e.g., jaw clenching) or cosmetic (e.g., wide or masculine appearance)
• Evaluation for surgical or non-surgical options depending on muscle vs. bone cause

2. Surgical Approach

• Typically performed under general anesthesia in a hospital setting
• Incisions are made inside the mouth (intraoral), so there are no external scars
• Bone shaving or partial resection is done to slim down the mandible angle (jawline)
• In cases of excessive muscle thickness, jaw Botox or masseter reduction may be combined
• Surgery duration ranges from 1.5 to 2.5 hours depending on the complexity

3. Recovery & Aftercare

• Facial compression bandages are worn for a few days to minimize swelling
• Temporary swelling, bruising, and numbness may occur for 1–2 weeks
• Liquid or soft diet is recommended for the first several days
• Follow-up appointments monitor healing and symmetry
• Sutures inside the mouth dissolve naturally within 7–10 days

Recovery & Aftercare

Recovery Timeline:

• Initial Swelling & Bruising: 7–14 days
• Return to Work/Daily Activities: Around 10–14 days
• Final Contour Results: Gradually become visible over 2–3 months as swelling resolves
• Strenuous Activity & Exercise: Avoid for at least 3–4 weeks

Following post-operative guidelines—especially oral hygiene, diet, and activity limitations—is critical to avoid complications and achieve optimal results.
