Treatment Overview
Square jaw reduction surgery targets the mandibular angle—the widest part of the lower jaw—to reduce its prominence and reshape the jawline. The procedure typically involves surgical bone removal or contouring, often combined with masseter muscle reduction. Korean surgeons use precise, minimally invasive methods to achieve a smooth and harmonious jaw contour without visible scarring.
Purpose & Benefits
The primary goals and benefits of square jaw reduction include:
- Softening a broad, angular jawline
- Creating a slimmer, more feminine or youthful lower face
- Improving facial balance and overall harmony
- Enhancing self-confidence and satisfaction with appearance
- Providing permanent and natural-looking results
This surgery is especially favored by individuals seeking a V-shaped or oval facial contour.
Ideal Candidates
Square jaw reduction surgery is suitable for individuals who:
- Have a wide, square, or prominent jawline
- Desire a more delicate or softer facial appearance
- Are in good health and have realistic expectations
- Wish for long-lasting results instead of temporary measures
- Have no contraindications for surgery
A detailed consultation with an experienced surgeon helps confirm candidacy.
Possible Risks & Complications
As with any surgery, possible risks include:
- Swelling, bruising, and temporary numbness
- Infection or bleeding (rare)
- Facial asymmetry if bone removal is uneven
- Damage to the mandibular nerve causing prolonged numbness (rare)
- Need for revision surgery in some cases
Selecting a skilled, board-certified surgeon reduces these risks.
Surgical Techniques Used
Korean clinics employ various advanced techniques such as:
- Mandibular Angle Reduction: Precise bone shaving or removal at the jaw angles.
- Masseter Muscle Reduction: Either through Botox injections or surgical excision to slim the jawline further.
- 3D Virtual Surgical Planning: Use of 3D imaging and computer simulation for accurate planning and outcomes.
- Intraoral Incisions: Accessing bone through mouth incisions to avoid visible external scars.
These techniques allow tailored and natural results for each patient.
Recovery & Aftercare
Recovery typically involves:
- Swelling and bruising for 1–2 weeks post-surgery
- Soft diet to avoid stress on the jaw
- Temporary numbness or stiffness in the jaw area
- Avoidance of strenuous activity for several weeks
- Regular follow-ups with the surgeon to monitor healing
Most patients resume normal activities within 2–3 weeks.
Results & Longevity
Square jaw reduction surgery provides permanent results with:
- A smoother, more slender jawline
- Enhanced facial balance and contour
- Long-lasting improvement in facial aesthetics
- Increased confidence and self-image
Final results usually appear as swelling subsides over several weeks to months.
