Mandibular angle reduction: shaving of the back jaw corners.
T-osteotomy / chin reduction: the front-chin reshaping that makes the V-line "V."
Cortical bone reduction: shaving the outer surface of the jaw line for a slimmer profile.
Buccal fat removal: often combined; not bone work but reshapes lower face.
Most "V-line packages" combine 2–3 of these. Don't combine more than
needed, every additional procedure compounds risk and recovery.
Realistic budget
Single procedure (e.g. just angle reduction): $5,000–$9,000.
Full V-line package (angle + T-osteotomy + cortical): $11,000–$18,000.
These prices reflect tier-vetted clinics only.
Recovery
Plan 14 to 21 days in Seoul. Liquid diet for 4 to 6 weeks post-op; some
swelling persists 4 to 6 months. Major activity restrictions for 8 weeks.
This is not a "fly in for a weekend" procedure.
What separates the best jaw / V-line clinics
Jaw contouring is the procedure with the highest skill-floor in Gangnam. The clinics on the shortlist are not interchangeable, and the gap between a top practice and the next tier down is measured in airway, nerve function, and decade-long facial structure.
Pre-op 3D CT planning as standard. The osteotomy is planned in software before the surgeon enters the OR; the resection is rehearsed virtually. Practices doing this freehand belong on a different list.
An in-house anesthesia and ICU step-down. This is the procedure with the highest airway-management complexity in cosmetic surgery. The OR and post-op need to be one continuous system, not a handoff.
A long-bone surgeon, not a generalist. Ask for the surgeon's training in maxillofacial or craniofacial surgery specifically; a general plastic surgeon doing 50 V-lines a year is not in the same category as a craniofacial specialist doing 300.
Conservative resection philosophy. The top practices do less than the marketing suggests. Over-resection ages catastrophically; under-resection is revisable. The clinics on this list lean under.
Long-term follow-up at year five. Bone surgery doesn't stop healing at six months. The best clinics have year-five imaging on the patients they operated on, and will show you.

"All-in" assumes anesthesiologist, 3D CT, two to three nights nursing, drainage management, and follow-up through day 14. Recovery-hotel cost (two to three weeks at $120 to $220 per night) is additional and meaningful.
Common variants, what each actually does
Mandibular angle reduction. Removes the back corner of the jaw bone. Changes the rear silhouette from "square" to "tapered."
T-osteotomy (genioplasty). Cuts the chin bone and repositions it backward, forward, or narrower. The "V" of V-line is almost always a T-osteotomy.
Cortical bone shaving. Sands the outer surface of the jaw line without changing its underlying structure. Subtle slimming, lower risk, often combined with the other two.
Buccal fat removal. Not bone work; removes cheek fat. Often packaged with V-line but is a separate decision with its own ageing concerns.
Two-jaw / orthognathic surgery. A different category: repositioning the entire upper and lower jaw, sometimes for cosmetic reasons, sometimes for functional. Higher complication rate, longer recovery, and only appropriate in a small subset of patients.
What a good outcome looks like at 1 / 6 / 12 / 24 months
Month 1. Heavy swelling; the face is unrecognizable. Chewing is limited to soft food. Numbness across the lower lip and chin is normal and frightening.
Month 3. Swelling resolves around 60%; sensation begins to return in patches. The new jaw line is becoming visible but still soft.
Month 6. 80% of swelling gone. Chin and jaw line read clearly. Numbness in most patients largely resolved; small persistent patches in some.
Month 12. Final shape. Scars (inside the mouth) invisible. Permanent sensation deficits, if any, are stable.
Month 24. Soft tissue has fully adapted to the new bone. Practices will compare at this point against the pre-op 3D plan to score the result.
"Bone surgery is permanent. Under-do it and you can revise; over-do it and the only revision is a graft."
Questions to ask at the consult
What is the surgeon's training in maxillofacial or craniofacial surgery, and how many V-lines have they personally performed in the past twelve months?
Is the surgical plan built from a 3D CT, and can I see the simulated result before signing?
Who is the anesthesiologist, and what airway-management equipment is in the OR?
What is the post-op nursing plan for the first 72 hours, and where am I staying?
What is the inferior alveolar nerve injury rate in your last 200 cases, and how is permanent numbness handled if it occurs?
What is the revision policy and what is my exposure if I need a graft?
Can I see twelve-month and ideally five-year photos of patients with my starting bone structure?
What is the protocol if I develop bone non-union or asymmetry at six months?
Will I need a chin strap or compression garment post-op, and for how long?
Is buccal fat removal recommended, and what is the ageing concern at age 50?
Red flags during the consult
No 3D CT, no simulation, freehand planning.
The clinic offers a "package" combining V-line with rhinoplasty and breast augmentation in the same week.
Aggressive over-resection enthusiasm ("we can make your chin much smaller").
Vague answers on inferior alveolar nerve risk.
Discount for cash, today, on a procedure that should never be a same-day decision.
No on-site overnight nursing for the first 48 hours.
The named surgeon is "matched on the day."
Frequently asked
Questions readers ask.
01How to reduce big square jaw?+
Fillers are often combined with Square Jaw Botox Treatment, particularly when jawbones become more accentuated due to fat or volume loss around the masseter muscles. Skin Tightening Treatments: RF microneedling and Ultherapy can tighten skin and reduce jowl appearance when volume loss or skin laxity is present.
02How much does a square jaw reduction cost?+
According to a 2020 article by RealSelf, the average cost of jaw reduction surgery was $7,325 with a range of $300 – $20,000.
03Is it possible to make your jaw less square?+
Jaw reduction is performed on adults of all ages. Jaw reduction can reshape the face, making it more narrow and oval. You may be a good candidate for jaw reduction surgery if you have a strong or square jaw and you desire to have the angle reduced.
04How to feminize a square jaw?+
Jaw shaving and reduction is a surgical procedure that permanently changes the appearance of your masculine jaw. During this procedure, a facial feminization surgeon will reduce the bone structure of the jaw, tapering the sides, reducing the bulk, and trimming the corners to make them appear round.
05Is a square jaw considered attractive?+
Certainly, many consider a square jaw attractive, particularly on men and female celebrities often embrace it as a part of their signature look (think: Margot Robbie and Jessica Simpson). On the other hand, others (often women) find the look overly broad or masculine.
06How painful is V-line surgery?+
Procedure for V-line jaw surgery Your face may be marked with a marker just before surgery in order to confirm the surgery sites. During surgery, you will feel no pain because you will be under general anesthesia. The surgeon will make incisions along your jawline and on your chin to begin the procedure.
07What does V-line surgery include?+
V-Line surgery is usually performed as an outpatient procedure, so you will not have to stay in the hospital overnight. During the process, Dr. Steinbacher may remove a double chin, decrease a thick chin, and reduce the jaw's width, length, and protrusion to achieve a more noticeable “V” shape to the jaw and chin area.
08Does V-line surgery cause sagging?+
Studies indicate that patients undergoing V-line surgery may experience a higher incidence of post-surgical sagging compared to less invasive procedures, particularly if the surgery involves removing more than 25% of the original bone volume.
