Mandibular angle prominence, often described as "noticeably sharp jaw corners," refers to an excessive development in the lower facial region that results in a wide, square, or overly prominent jawline. While not a specific medical diagnosis, this term covers a range of underlying conditions that create a bulky or disproportionate lower face. The prominence can be due to an enlarged lower jawbone (mandible), an enlarged chewing muscle (masseter), or both. In this context, "mandibular prominence" refers to the visible facial characteristic, not the embryological structure.
When researching "mandibular angle prominence," patients may come across related terms like "bulky jawline," "square jaw," "wide lower face," and "prominent mandibular angle." Other associated conditions include "prognathism" (a protruding lower jaw), "extended chin," and "underbite," all of which can affect the lower facial contour.
There are two main anatomical causes for a bulky jawline. The first is bony protrusion, where the lower jawbone is enlarged or excessively wide. This is especially common in East Asian populations, making mandibular angle osteotomy a preferred treatment in those regions. The second is enlarged masseter muscle, known as masseter hypertrophy. This rare condition can be linked to malocclusion (improper bite), bruxism (teeth grinding), clenching, TMJ disorders, or chronic jaw clenching due to stress. Often, both bone and muscle contribute to a bulky jawline.
A prominent mandibular angle can impact more than just appearance. Psychologically, individuals may feel self-conscious, describing their face as "hard," "angry," or "fighter-like," which can affect confidence and social interactions. Many seek treatment to achieve a softer, more balanced, or "V-shaped" face, especially women who desire a more feminine look.
Functionally, a bulky jawline can cause issues like malocclusion, making chewing, biting, and speaking difficult. It can also lead to dental wear, cavities, gum disease, chronic jaw pain, TMJ disorders, sleep apnea, snoring, and headaches. Surgical correction can resolve problems like lip strain and jaw clicking. This shows that "Square Jaw Surgery" is not just cosmetic—it can improve quality of life by addressing both appearance and function. Patients should consider both aspects during consultation for a more complete understanding of the procedure's benefits.
Cultural preferences also play a role. In East Asian aesthetics, a "square face" is often seen as "rough and lacking delicacy," while an "oval face" or "egg-shaped face" is preferred. This cultural context drives the popularity and advancement of mandibular angle reduction surgery in places like South Korea, where the goal is often to align with specific beauty standards rather than just correct deformities.
Square Jaw Surgery: A Detailed Medical Overview
"Square Jaw Surgery" refers to a range of surgical procedures aimed at reducing the prominence of the lower jaw to create a slimmer, more refined, or "V-shaped" facial contour. Other names include Mandibular Angle Reduction, Jaw Reduction, V-Line Surgery, and, in gender affirmation contexts, Feminizing Jaw Surgery. The main goal is to soften a wide or angular jawline, making the face appear smaller, slimmer, and more balanced. For women, the focus is often on achieving a softer, more rounded jawline.
The surgery is typically performed through incisions inside the mouth, leaving no visible external scars. General anesthesia is always used for patient comfort and safety.
Key surgical techniques include:
- Mandibular Angle Reduction / Resection (Osteotomy): The core technique involves shaving or removing parts of the jawbone to soften the angle and reduce flaring. Surgeons use precise cutting guides, with techniques tailored to each patient's anatomy.
- Long-Curve Jaw Reduction: This advanced method creates a smooth, natural curve from ear to chin, preventing "secondary angles" or an artificial look.
- Cortical Bone Shaving/Resection: This targets the jawbone's outer layer to reduce thickness, slimming the face from the front. It can reduce jawbone width by 3 mm to 10 mm per side.
- Masseter Muscle Reduction: If the masseter muscle is enlarged, reducing it can further refine the jawline.
- High-Frequency Nerve Block: Used to shrink the masseter muscles.
- Botulinum Toxin (Botox): A non-surgical option or adjunct for masseter hypertrophy, though surgery offers more permanent results.
- Surgical Resection of Masseter Muscle: Sometimes, part of the muscle is surgically removed.
- Adjunctive Procedures:
- Buccal Fat Removal: Removes cheek fat for a more contoured look, sometimes done alongside jaw reduction.
- Chin Tip Surgery (Genioplasty/T-Osteotomy): Narrows the chin for a more natural V-line, especially in patients with a wide U-shaped jaw.
Modern square jaw surgery emphasizes a smooth, natural contour and avoids creating secondary angles. Techniques like long-curve jaw reduction and cortical bone shaving reflect a shift toward sculpting harmonious, natural results from all angles. Advanced clinics use 3D-CT scans for detailed pre-surgical planning, allowing surgeons to identify nerve lines and customize bone reduction for each patient. This technology reduces the risk of complications and ensures precise, symmetrical outcomes. Bone reduction is tailored to factors like jaw development, ear and lip position, gender, ethnicity, and aesthetic goals, with typical reductions of 1.5 cm to 4 cm.

The Patient Journey: Undergoing Square Jaw Surgery in South Korea
The process for square jaw surgery, especially for medical tourists in South Korea, is structured from consultation to recovery.
Initial Consultation and Pre-operative Assessment
Patients often start with a remote consultation, where surgeons assess jaw development, ear and lip position, gender, ethnicity, and aesthetic preferences. A thorough in-hospital exam and 3D-CT scans follow, providing detailed anatomical information for a customized surgical plan.
The Surgical Procedure: Anesthesia, Incision, and Duration
General anesthesia is standard, with a full-time anesthesiologist monitoring the patient. All incisions are inside the mouth, leaving no visible scars. Surgery typically lasts 40-90 minutes, but can take up to 2-3 hours for complex cases.
Typical steps include:
- Resection of the square jaw, extending to the chin and avoiding secondary angles.
- Lateral cortical bone shaving for a slimmer appearance.
- Masseter muscle reduction, often via high-frequency nerve block.
- Additional procedures like buccal fat removal or chin tip surgery as needed.
Immediate Post-operative Care and Hospital Stay
Patients usually stay in the hospital for 1-4 days for monitoring and follow-up. This ensures prompt management of any complications and professional care during the initial recovery.
Recovery Timeline and Post-Surgery Management
Sutures are removed around 10-14 days post-surgery. The initial recovery period is 7-14 days, with most patients resuming light activities after two weeks. Swelling is common and can take up to six months or a year to fully resolve. Leading clinics offer advanced post-op care, including LED therapy, ultrasound, and radiofrequency treatments to speed healing and reduce swelling.
Patients should eat soft foods for about a week and avoid hard or chewy foods and strenuous activities for 1-2 months. Discomfort is usually manageable with painkillers. Temporary numbness may occur but typically resolves as nerves heal. Infection risk is minimized with proper wound care and mouthwash. Smoking should be avoided to ensure proper healing. Skin sagging is rare but possible, especially in patients with poor skin elasticity or excess fat; some clinics recommend combining the procedure with a facelift if needed. Risks like swelling, scarring, infection, and bleeding are minimized by experienced surgeons and thorough pre-op consultations. Medical tourists can usually fly home 5-7 days after surgery, but full recovery should be considered. Patients with braces can undergo surgery, but orthodontic adjustments should wait 2-3 months.
Safety Protocols and Patient Support Systems in Korean Clinics
Korean clinics are known for strict safety protocols, including full-time anesthesiologists, comprehensive pre-surgical exams, and advanced imaging for surgical planning. These measures, combined with experienced specialists, greatly reduce the risk of complications.

Patient Outcomes and Satisfaction: What to Expect
Patients often wonder about the results and satisfaction rates after square jaw surgery.
Achieving Aesthetic Goals: A Slimmer, More Balanced Jawline
The main aesthetic result is a softer, slimmer, and more balanced jawline. For women, this often means achieving a "V-shaped" jawline. The procedure can reduce jaw width by 3 mm to 10 mm per side. Advanced techniques ensure natural-looking results and avoid an artificial appearance.
Functional Improvements and Enhanced Quality of Life
Beyond aesthetics, jaw surgery can correct malocclusion, improve chewing, and address TMJ disorders. Studies show significant improvements in chewing function and facial aesthetics after surgery. These functional gains can boost self-esteem and confidence, positively affecting social interactions and quality of life.
Patient Satisfaction Rates and Key Contributing Factors
Satisfaction rates are high, with studies reporting 88.6% of patients satisfied and average ratings of 8.13 out of 10. Most patients seek both aesthetic and functional improvements, and satisfaction is linked to gains in both areas. Clear communication and realistic expectations are crucial for positive outcomes. The procedure often leads to enhanced self-esteem and psychological well-being, not just physical changes.
Managing Expectations: Recovery Realities and Potential Side Effects
Patients should expect significant swelling, with initial improvements visible in 2-3 weeks but final results taking up to a year. Understanding this timeline helps manage expectations and reduces anxiety. The procedure is relatively painful, but discomfort is manageable with medication. Temporary numbness and infection risk are possible but usually resolve with proper care. Skin sagging is rare but can be addressed if needed. Risks are minimized by experienced surgeons and thorough consultations.
Conclusion
Mandibular angle prominence can affect both appearance and function, but "Square Jaw Surgery" offers a comprehensive solution for a slimmer, more balanced jawline. The procedure combines advanced surgical techniques, personalized planning, and thorough aftercare, especially in leading destinations like South Korea. Patients should seek consultations with qualified surgeons, understand both the aesthetic and functional benefits, and set realistic expectations for recovery. With careful planning and expert care, square jaw surgery can deliver transformative results and improved quality of life.
