Sliding Genioplasty in Korea (2026): Technique, Candidacy and Recovery

Q: Will there be a visible scar?

The standard approach is inside the lower lip, so there is generally no external facial scar.

Q: Can the result be reversed?

Not straightforwardly. Revision is possible but requires a further osteotomy, unlike an implant which can be removed.

Sliding genioplasty is a chin-repositioning operation in which the lower border of the jaw is cut and the bone segment is moved forward, backward, upward, or downward, then fixed with plates and screws. It changes the chin bone itself rather than adding an implant.

Most English-language pages on chin surgery in Korea compare implants to fillers and treat genioplasty as a footnote. That skips the decision that actually matters for many international patients: whether the goal is projection alone, vertical height change, or asymmetry correction — because implants can address only the first of those. This guide explains what sliding genioplasty can and cannot achieve, who is typically considered a candidate, how recovery unfolds week by week, and what to verify before booking surgery in Seoul in 2026.

What Sliding Genioplasty Actually Does

The surgeon makes an incision inside the lower lip, exposes the chin bone, and performs a horizontal osteotomy below the tooth roots and below the mental nerve. The freed segment is then repositioned in one or more planes and fixed with titanium plates.

Because the segment is moved rather than augmented, the procedure can advance the chin, set it back, shorten a vertically long chin by removing a wedge of bone, lengthen a short chin, or rotate the segment to correct left-right asymmetry. Combinations are common. An implant, by contrast, adds volume in front of existing bone and cannot shorten a chin or correct a true vertical discrepancy.

Sliding Genioplasty vs Chin Implant vs Filler

A chin implant is a shorter operation with no osteotomy, generally lower cost, and is reversible by removal — but it addresses projection only, and long-term bone resorption beneath implants has been described in the literature. Filler is non-surgical and temporary, typically lasting months rather than years, and is best suited to small refinements or to previewing a change.

Sliding genioplasty is the more invasive option with the broader corrective range. It is generally favoured when the vertical dimension is wrong, when asymmetry is significant, when a set-back is required, or when the amount of advancement needed is beyond what an implant can produce naturally. Surgeons vary in where they draw these lines; the reasoning behind a recommendation matters more than the recommendation itself.

Who Is Typically Considered a Candidate

Candidacy is usually assessed on cephalometric and 3D CT imaging rather than on photographs alone. Commonly considered factors include skeletal maturity (generally after growth completion, often around age 18 or later), adequate bone height below the tooth roots for a safe osteotomy, the relationship of the chin to the lower lip and nose in profile, and dental occlusion.

An important screening point: if the bite itself is misaligned, chin surgery alone may camouflage rather than correct the underlying skeletal relationship. Some patients are more appropriately assessed for orthognathic (jaw) surgery, sometimes with orthodontic preparation. A clinic that proposes genioplasty without reviewing occlusion is skipping a step. Patients whose main concern is lower-face width rather than chin position may be evaluated for different procedures entirely — our comparison of V-line surgery: bone vs fat vs buccal fat covers that distinction.

The Mental Nerve: The Risk Most Guides Under-Explain

This is the section most consumer pages omit. The mental nerve exits the jaw on each side and supplies sensation to the lower lip and chin. The osteotomy is planned below it, but the nerve is retracted during surgery and temporary altered sensation — numbness or tingling of the lower lip and chin — is a recognised and relatively common early finding after genioplasty.

Published series generally report that most sensory disturbance resolves over weeks to months, while a smaller proportion of patients report persistent altered sensation. Reported rates vary substantially between studies depending on technique and follow-up length, so no single figure should be presented as definitive. Ask your surgeon for their own experience, their planning margin below the nerve, and how they document sensory recovery at follow-up. Other recognised risks include infection, plate palpability or the need for later plate removal, bleeding, asymmetry, and dissatisfaction with the aesthetic result.

Recovery: A Realistic Timeline

Days 1 to 3 typically involve the most swelling, a soft or liquid diet, and taped or elastic support depending on protocol. Days 4 to 10 usually see swelling begin to decline; intraoral sutures are often dissolvable or removed in this window. Many patients are advised that they look socially presentable at roughly 2 to 3 weeks, though visible swelling commonly persists longer.

Bone union continues for months. Surgeons frequently advise avoiding contact sports and significant facial impact for around 2 to 3 months, and final contour is often described as settling over 6 to 12 months. Oral hygiene protocols are strict because the incision is intraoral. These are general patterns reported in practice; your surgeon’s protocol takes precedence.

What This Means for International Patients

Because sliding genioplasty involves fixation hardware and an intraoral wound, in-person follow-up matters more than for soft-tissue procedures. Many clinics advise international patients to plan roughly 10 to 14 days in Korea, covering the immediate post-operative checks and suture management, though requirements vary by surgeon and by whether the procedure is combined with other operations.

Before booking, confirm: who performs the surgery (not only who consults), whether 3D CT is included in the workup, what happens if plate removal is later required after you have returned home, and how post-operative imaging and records will be provided to you for continuity of care. Independent verification of credentials is essential — see our 15-point clinic vetting checklist.

Cost Structure and What to Ask For

Quotes for facial bone surgery in Korea generally bundle several components, and headline figures are frequently incomplete. Request an itemised breakdown separating surgeon fee, anaesthesia, hospital or facility charges, pre-operative imaging (3D CT), hardware, post-operative visits, and any charge for revision. Ask explicitly whether the quoted price assumes general anaesthesia and an overnight stay, and whether combined procedures are discounted or billed separately. Prices vary widely by clinic and surgeon experience and are subject to exchange-rate movement.

Frequently Asked Questions

Is sliding genioplasty permanent?

The bone repositioning is intended to be permanent once healed, unlike filler. Plates are often left in place indefinitely but can be removed if they cause symptoms.

Will there be a visible scar?

The standard approach is through an incision inside the lower lip, so there is generally no external facial scar. An external approach is used less commonly and would leave a small scar under the chin.

Can it be combined with other facial bone surgery?

It is frequently planned alongside jaw angle or cheekbone procedures. Combining operations may lengthen anaesthesia time and recovery and should be discussed as a single risk profile rather than as separate procedures.

How long does numbness last?

Temporary altered lower-lip sensation is common early after surgery and most reports describe resolution over weeks to months. A minority of patients report longer-lasting change. Discuss individual risk with your surgeon.

Can the result be reversed?

Not straightforwardly. Revision is possible but involves a further osteotomy. This asymmetry with implants — which can be removed — is a central consideration when choosing between the two.

Next Steps

If you are evaluating sliding genioplasty in Korea, bring imaging and a written question list to at least two consultations, and confirm that occlusion has been assessed before surgery is proposed.
