What It Is
Mandibular angle reduction is a surgical procedure that reshapes and reduces the prominent angles of the lower jaw (mandible). It is often chosen by individuals with a wide or square jawline who wish to achieve a slimmer, softer, and more oval-shaped lower face.
In Korea, mandibular angle reduction is a cornerstone of facial contouring surgery. Korean plastic surgeons are globally recognized for their skill in jaw reshaping, often combining advanced surgical planning, 3D imaging, and minimally invasive techniques to deliver precise and natural results.
Why It’s Done
Cosmetic Goals:
- Slim down a broad or square jawline
- Create a softer, more feminine lower face contour
- Harmonize facial proportions with the chin and midface
Functional Considerations:
- Correct asymmetry in the lower jaw
- Improve overall balance of facial features, sometimes combined with chin surgery
Patient Factors:
- Common among young adults seeking the popular V-line face shape
- Beneficial for patients with strong, angular jawbones or wide lower faces
- Best suited for non-smokers and individuals in good general health
Alternatives
- Masseter Botox Injections: Reduce the size of enlarged jaw muscles; non-surgical but temporary
- Dermal Fillers or Fat Grafting: Improve balance between the chin, cheek, and jaw without bone reduction
- V-Line Jaw Reduction: A more comprehensive surgery combining mandibular angle reduction with chin reshaping
- Orthognathic Surgery: For patients with severe jaw misalignment or bite problems
Preparation
Before mandibular angle reduction in Korea, patients typically undergo:
- Consultation: 3D CT imaging and simulation of expected results
- Health Evaluation: Bloodwork, dental or orthodontic assessments if needed
- Lifestyle Adjustments: Avoid smoking, alcohol, and blood-thinning medications several weeks before surgery
- Fasting: Required for 6–8 hours before general anesthesia
How It’s Done
Type: Surgical, performed under general anesthesia
Duration: 2–4 hours depending on complexity
Procedure Steps:
- Incisions are made inside the mouth (intraoral approach), leaving no visible scars
- The surgeon exposes the mandibular angle
- Excess bone is shaved, trimmed, or removed to refine the angle and jawline curve
- The jaw is smoothed for a natural, symmetrical contour
- Incisions are closed with dissolvable sutures
Hospitalization: Usually requires 1–2 nights for monitoring
Recovery
- First Week: Significant swelling and some bruising; discomfort managed with pain medication
- Diet: Soft or liquid foods due to intraoral incisions
- Oral Care: Antiseptic rinses to reduce infection risk
- Activity: Patients usually resume normal life in 2–3 weeks, though swelling continues to subside gradually
- Final Results: Fully visible within 3–6 months as swelling resolves and tissues settle
Possible Complications
- Swelling and bruising (common during recovery)
- Temporary or permanent numbness in the lower lip or chin due to nerve involvement
- Infection at the surgical site
- Asymmetry if bone removal is uneven
- Jaw weakness or functional issues (rare when performed by experienced surgeons)
Treatment Options in Korea
Diagnosis
Korean clinics use:
- 3D CT Scans for detailed bone mapping
- Computerized Simulation to preview surgical results
- Specialist Consultations with plastic surgeons and maxillofacial experts
Medical Treatments
- Non-surgical Masseter Botox for muscle-related jaw width
- Fillers or Fat Grafts for facial balance without bone surgery
Surgical or Advanced Therapies
- Standard Mandibular Angle Reduction: Bone shaving or trimming
- Cortical Shaving: Surface refinement for smoother lines
- Combined Procedures: Often paired with chin surgery, zygoma reduction, or V-line contouring for comprehensive results
Rehabilitation and Support
- Frequent post-op follow-ups to ensure healing and symmetry
- Swelling reduction therapies like lymphatic drainage offered by many clinics
- International patient support services, including translation, recovery assistance, and long-term monitoring
Advantages of Mandibular Angle Reduction in Korea
- World-Class Expertise: Korean surgeons are leaders in facial bone contouring procedures
- Advanced Technology: Use of 3D simulations, surgical navigation systems, and refined bone-cutting tools
- Natural Results: Emphasis on harmony and proportionality instead of overly dramatic changes
- Comprehensive Care: Clinics provide extensive aftercare and concierge services for international patients
- Cost Efficiency: More affordable compared to Western countries while maintaining top global standards
