Achieve the Perfect V-Line with Korean Jaw Reduction Surgery

 

 

Square jaw reduction surgery, also known as mandible reduction surgery, is a popular cosmetic procedure in Korea designed to reshape the lower jaw to create a more V-shaped or oval facial contour. This surgery is particularly sought after in Korea, where softer lower-face contours are widely preferred, although the right jawline always depends on each patient’s own goals and facial structure. Understanding the costs, procedure details, recovery process, and the possibility of combining it with other surgeries like chin tip and cheekbone reduction is crucial for anyone considering this transformative procedure.

Understanding Square Jaw Reduction Surgery

Square jaw reduction surgery involves the surgical contouring of the jawbone to reduce its width and create a more streamlined and aesthetically pleasing shape. This procedure is typically performed under general anesthesia by a qualified maxillofacial or plastic surgeon.

 

 

Square Jaw Reduction vs. Jaw Shaving, V-Line Surgery, and Genioplasty

These terms are often used interchangeably online, but they describe different surgical scopes. In this article, they are used as follows.

 

 

How Jaw Contouring Trends Have Changed in 2025–2026

The goal of jaw reduction has shifted. Rather than making the lower face as small as possible, patients and surgeons increasingly aim for proportion: a jawline that is softer but still defined, and that keeps natural expression and stable soft tissue over time.

• Less is often more: conservative, proportion-focused reduction is preferred over aggressive bone removal, because excessive reduction can leave the lower face looking hollow or sagging as the patient ages.

• Diagnosis before surgery: patients are more aware that a wide face can come from muscle or fat, and they expect CT-based analysis rather than a one-size-fits-all V-line.

• Different goals, different designs: some patients want a slim oval face, while others want to keep a strong, angular jaw and only refine asymmetry or width. Both are valid design goals.

• Weight-loss medication: with GLP-1 drugs now widely used, more patients are losing facial fat before or around the time of surgery, which changes how the jawline looks and how surgery should be timed (see the next section).

How the Surgery is Done

Consultation and Planning

The process begins with a thorough consultation with the surgeon. During this stage, the surgeon assesses the patient’s facial structure, discusses the desired outcome, and plans the surgery. Advanced imaging techniques, such as 3D CT scans, are often used to create a detailed map of the jawbone. At AB Plastic Surgery Korea, pre-operative health screening is carried out in-house with a clinical pathologist on staff, and the clinic can perform blood cross-matching on site so that compatible blood can be prepared quickly if an emergency arises.

 

Anesthesia

On the day of the surgery, the patient is placed under general anesthesia to ensure comfort and pain-free operation. At AB Plastic Surgery Korea, a board-certified anesthesiologist is on-site and monitors the patient from induction through recovery. The clinic states that anesthesiology specialists make up 47.1% of its medical staff and that it has had zero reported medical accidents since opening in September 2020.

 

Incision and Bone Shaving

The surgeon makes incisions inside the mouth to access the jawbone, avoiding visible scars. Using specialized surgical tools, the surgeon carefully shaves and reshapes the outer layer of the jawbone to reduce its width and prominence. In some cases, the surgeon might also remove a portion of the bone if necessary.

 

Contouring and Smoothing

After the initial reduction, the bone edges are smoothed and contoured to achieve a natural look. The surgeon ensures that the jawline is symmetrical and balanced with the rest of the facial features.

 

Closing the Incisions

The incisions inside the mouth are closed with dissolvable stitches, and the patient is monitored as they wake up from anesthesia.

 

 

 

Is Square Jaw Reduction Right for You? Causes, Candidates, and Limits

 

What Makes the Lower Face Look Wide? Matching the Cause to the Treatment

A wide lower face is not always a bone issue. Identifying the cause is the first step, because jaw reduction cannot correct width that comes from muscle or fat.

Not every patient wants the same result. Some prefer a softer oval outline, while others want to keep a defined, angular jaw and only refine its proportions. If you want to understand how jawline design is adjusted to different face shapes and preferences, read how AB Plastic Surgery Korea customizes jawline design.

 

 

Factors Assessed at Consultation

• Jawbone width and angle shape on 3D CT

• Position of the nerve canal running inside the lower jaw, which limits how much bone can be safely reduced

• Masseter muscle thickness and soft-tissue thickness

• Facial symmetry, chin shape, and cheekbone width (to judge whether jaw reduction alone will look balanced)

• Bite and dental condition, general health, current medications, and any previous facial surgery

 

 

What Jaw Reduction Cannot Do

• It does not reduce muscle bulk or facial fat.

• It does not correct a misaligned bite.

• Bone reduction is limited by nerve position, so a very wide jaw may narrow less than expected.

• Some pre-existing asymmetry can remain, because both sides of the face are rarely identical to begin with.

 

 

Taking GLP-1 Weight-Loss Medication? Timing and Disclosure

Weight-loss medications such as semaglutide and tirzepatide have become a common part of pre-surgery conversations. They matter for jaw reduction in two ways.

• Anesthesia safety: the American Academy of Facial Plastic and Reconstructive Surgery notes that these drugs slow stomach emptying, which can raise the risk of aspiration under anesthesia, and that a pause before surgery is commonly recommended. The exact timing is set case by case, so tell both your surgeon and anesthesiologist if you take one.

• Surgical timing: losing facial fat can make the jaw angle look sharper, or reveal that fat, not bone, was the main cause of width. If you are still losing weight, it is usually better to reassess your face once your weight has stabilized before deciding how much bone to reduce.

If weight loss has left your face looking hollow or loose rather than wide, a different approach may fit better; read about treatment options for Ozempic face.

 

 

Possible Risks and How They Are Managed

Like any bone surgery under general anesthesia, square jaw reduction carries risks. Reported risks include swelling and bruising, bleeding or hematoma, infection, temporary or, rarely, lasting numbness of the lower lip and chin, asymmetry, irregular contour, and soft-tissue sagging after bone volume is reduced. Pre-operative CT planning, careful surgical technique, and close post-operative monitoring are used to lower these risks; the surgeon should explain how each one applies to your anatomy. For more surgeon-written explanations of facial bone surgery, read AB Plastic Surgery Korea’s medical column.

The recovery period following square jaw reduction surgery is crucial for achieving the best results. Here’s a detailed look at what to expect during recovery. 

 

 

 

Recovery Process after Square Jaw Reduction Surgery

 

 

 

This case shows jaw reduction combined with chin tip surgery, so the change should not be read as the result of jaw reduction alone.

 

 

Initial Recovery (1-2 Weeks)

• Swelling and Bruising: Significant swelling and bruising are common in the first week. The use of cold compresses and prescribed medications can help manage these symptoms.

• Diet: A soft or liquid diet is recommended to avoid stressing the jaw. Foods that require minimal chewing are ideal.

• Pain Management: Pain and discomfort can be managed with prescribed painkillers. It’s important to follow the surgeon’s instructions regarding medication.

• Oral Hygiene: Because the incisions are inside the mouth, keeping the mouth clean as instructed helps protect the healing wounds.

 

 

Mid-Term Recovery (3-6 Weeks)

• Reduced Swelling: Swelling begins to subside, and the initial results of the surgery become more apparent.

• Gradual Diet: Patients can slowly reintroduce solid foods as tolerated.

• Follow-Up Visits: Regular follow-up appointments with the surgeon are essential to monitor healing and address any concerns.

 

 

Long-Term Recovery (3-6 Months)

• Final Results: It may take several months for the swelling to completely subside and for the final results to be visible.

• Normal Activities: Most patients can resume normal activities within a few weeks, but strenuous activities and heavy lifting should be avoided for at least a month.

 

 

Returning to Work vs. Seeing the Final Result

Recovery can take longer when several bones are contoured at once, when there is more soft-tissue swelling, or when the patient has had previous facial surgery. For a broader look at how recovery differs across facial contouring procedures, see the facial contour surgery recovery guide.

 

 

When to Contact Your Clinic Right Away

Contact your clinic, or seek local emergency care if you are already home, if you notice:

• Swelling that suddenly increases on one side, or a firm, tense swelling

• Bleeding from inside the mouth that does not stop with gentle pressure

• Fever, pus, a foul taste, or pain that worsens after it had been improving

• Difficulty breathing or swallowing

 

 

 

Planning Square Jaw Reduction in Korea as an International Patient

Korea has become one of the busiest medical travel destinations in the world. According to the Ministry of Health and Welfare (April 2026), foreign patients visiting Korea passed 2 million for the first time in 2025, up from 1.17 million the year before, with plastic surgery accounting for 11.2% of cases. Patients from the United States rose by about 70% to a record 173,000. With demand at this level, careful planning matters more than ever.

 

 

Before You Travel

• Online pre-consultation: share clear front and side photos so the team can give an initial opinion, but expect the final plan only after an in-person CT.

• Medications: list all prescriptions and supplements, including any weight-loss medication, and confirm what to pause before surgery.

• Visa: AB Plastic Surgery Korea was designated a 2025 Excellent Medical Tourism Attraction Institution by Korea’s Ministry of Justice, which allows eligible patients to apply for a medical e-visa through a streamlined process.

 

 

During Your Stay in Korea

• Before surgery: allow time for the in-person consultation, 3D CT, and pre-operative health screening before the operation date.

• Before your flight home: attend the post-operative check your surgeon schedules and confirm that you are cleared to fly. Ask for a written summary of the procedure performed and your medication instructions.

• Buffer days: leave flexibility in your return flight in case swelling or follow-up timing requires a longer stay.

 

 

After You Return Home

AB Plastic Surgery Korea provides a personal patient manager for follow-up questions and operates a 24-hour emergency call line for post-operative concerns. Keep your surgical summary on hand in case you need to see a local doctor, and send progress photos when your coordinator requests them so the team can check your healing remotely.

 

 

 

Combining Square Jaw Reduction with Other Procedures

To achieve a more harmonious facial appearance, square jaw reduction surgery can be combined with other procedures such as chin tip surgery and cheekbone reduction surgery. The decision should be based on facial proportions rather than on a preset package. For a detailed look at when combined contouring makes sense and when it does not, read our guide to combining facial contouring procedures.

 

 

Chin Tip Surgery

Chin tip surgery, or genioplasty, involves reshaping the chin to improve facial balance and harmony. This procedure can enhance the results of jaw reduction surgery by further refining the jawline and creating a more V-shaped facial contour.

 

Chin Tip Surgery Procedure

In bone genioplasty, the surgeon makes an incision inside the mouth, cuts the chin bone, and moves it forward, backward, shorter, or narrower before fixing it in place. A chin implant is a separate option: a pre-shaped implant is placed over the existing bone through an incision inside the mouth or under the chin, adding projection without cutting the bone. Which approach fits depends on whether the chin needs to be shortened or narrowed (bone surgery) or mainly needs more forward projection. For a full explanation of methods and costs, read the genioplasty guide.

 

When It Is Considered and When It Is Not Needed

• Usually considered: when the chin looks long, wide, or recessed relative to the narrowed jaw, so the lower face would not form a smooth line after jaw reduction.

• Usually not needed: when the chin length and projection already match the planned jawline.

 

Recovery after Chin Tip Surgery

Similar to jaw reduction surgery, the recovery involves swelling, bruising, and a soft diet initially. Full recovery can take several weeks.

 

 

 

Cheekbone Reduction Surgery

Cheekbone reduction surgery, or zygoma reduction, reduces the prominence of the cheekbones to create a softer facial appearance. This procedure can be particularly beneficial for individuals with wide or prominent cheekbones that detract from the overall facial harmony.

 

Cheekbone Surgery Procedure

The surgeon makes incisions inside the mouth and/or along the hairline to access the cheekbones. The bones are then reshaped or repositioned to achieve a more balanced look.

 

When It Is Considered and When It Is Not Needed

• Usually considered: when the widest point of the face is the cheekbones, so a narrower jaw would make them look even more prominent.

• Usually not needed: when cheekbone width is already in proportion, or when the cheek area looks full because of soft tissue rather than bone.

 

Recovery after Cheekbone Surgery

Recovery involves managing swelling and bruising, with a similar timeline to jaw reduction surgery. Patients are advised to follow a soft diet and avoid strenuous activities during the initial recovery period.

 

 

Soft-Tissue Sagging After Bone Reduction

When bone volume is reduced, the skin and soft tissue that it supported need to adapt. In patients with thinner skin or early signs of aging, this can show as looseness along the jaw or cheeks. Current practice therefore pays more attention to soft-tissue support: limiting reduction to what the face needs, preserving attachments where possible, and, in selected patients, planning lifting at the same time or later. Ask your surgeon how your skin quality and age affect this risk.

 

 

 

Costs of Square Jaw Reduction Surgery in Korea

Square jaw reduction surgery in Korea involves several costs, including surgeon's fees, anesthesia, hospital or clinic fees, and medical tests and imaging. The surgeon's fees vary based on their experience and reputation. General anesthesia is required for the procedure, adding to the overall cost, as do the fees for using the surgical facility and receiving pre- and post-operative care. Additionally, pre-surgical tests and imaging are necessary. For the exact prices you can contact AB Plastic Surgery Korea’s customer center for a personalized quote. 

 

 

Facial Contouring Surgery Starting Prices at AB Plastic Surgery Korea

The overall cost of square jaw reduction surgery in Korea depends on the surgical technique, facial bone structure, and whether additional contouring procedures are combined.

The prices below are AB Plastic Surgery Korea’s own starting prices, not averages for Korea as a whole. Prices at other clinics may differ.

Important: Surgery costs may vary depending on individual facial anatomy, CT scan analysis, surgical complexity, hospitalization period, and personalized treatment planning. Because every facial structure is different, the exact cost can only be determined after a detailed consultation and CT analysis with the surgeon. USD figures are approximate conversions and may change with the exchange rate.

Frequently Asked Questions About Square Jaw Reduction Cost

How much does square jaw reduction cost in Korea?

At AB Plastic Surgery Korea, square jaw reduction starts at KRW 7,700,000 (about USD 5,240, pricing date April 2026). The final fee is set after a consultation and 3D CT, and increases if chin or cheekbone surgery is added.

 

Will jaw reduction slim my face if the width comes from muscle?

No. Bone surgery does not reduce the masseter muscle. When muscle is the main cause, muscle-relaxing injections are usually discussed first. The consultation and CT help distinguish bone, muscle, and fat.

 

Can I have jaw reduction while taking a GLP-1 weight-loss medication?

Tell your surgeon and anesthesiologist before booking. These medications slow stomach emptying, so a pause before general anesthesia is commonly recommended, and if you are still losing weight it is usually better to reassess your face once your weight is stable.

 

How long should I stay in Korea?

Plan for the consultation and pre-operative tests, the surgery, and the post-operative check your surgeon schedules before you fly. Confirm your clearance to fly before booking a fixed return date, and keep buffer days in case your follow-up needs to be adjusted.

 

Is general anesthesia for jaw surgery safe?

No surgery under general anesthesia is risk-free. At AB Plastic Surgery Korea, a board-certified anesthesiologist stays on-site throughout, operating rooms are monitored by CCTV, and an emergency response system is in place. Ask your surgeon how your health history affects your anesthesia plan.

 

 

 

How to Choose a Safe Clinic for Square Jaw Reduction in Korea
