Double jaw surgery at EU Oral & Maxillofacial Surgery: how it differs from a cosmetic clinic
EU treats double jaw surgery as the correction of a skeletal malocclusion, not a cosmetic operation. That is why it is performed by oral & maxillofacial surgeons who understand the facial bones, the teeth and the jaw joint together, working alongside an in-house orthodontist.

Why an oral & maxillofacial surgeon
EU states that double jaw surgery is inseparable from the bite and strongly affects jaw-joint movement. Operating without accounting for chewing, speech and joint function can produce serious harm, and this knowledge comes from dental school and oral & maxillofacial training.
For the same reason every case is planned in close cooperation with the hospital's own orthodontist, from pre-surgical planning through post-operative alignment.
Conditions EU treats with double jaw surgery
Protruding jaw (주걱턱), facial asymmetry (안면비대칭), long face (긴얼굴), receding chin (무턱) and severe mouth protrusion (돌출입) — each with its own page on the hospital's site.
When the problem is confined to the lower jaw, EU offers mandible-only surgery (하악수술) instead of operating on both jaws.
What aftercare looks like
Per EU's published aftercare: water from 6–8 hours after surgery, liquid food from the next day, a compression face band for about two weeks, chlorhexidine rinses three times a day for two weeks, and follow-ups at one week, two weeks and one month after discharge.
Swelling peaks on days 2–3, starts to fall after the first week, largely settles at about one month and mostly resolves by three months; EU provides two weeks of laser de-swelling care.

Double jaw surgery (양악수술)
Both jaws are repositioned to correct a skeletal imbalance and the malocclusion it causes. EU frames it as functional treatment rather than cosmetic surgery, performed by oral & maxillofacial surgeons together with an orthodontist.
Protruding jaw correction (주걱턱)
EU begins by separating whether the protruding jaw comes from an over-developed mandible, a retruded maxilla, or both — each requires a different surgical plan.
Facial asymmetry correction (안면비대칭)
Skeletal asymmetry is assessed across the occlusal plane, chin position and the length of each side of the jaw. EU explains that some cases need a degree of overcorrection to end up genuinely balanced.
Long face correction (긴얼굴)
A long face often comes with a gummy smile, lip incompetence and a receding chin. EU stresses diagnosis: a vertically excessive maxilla is treated by impacting the upper jaw, not by shortening the chin.
Receding chin correction (무턱)
A receding chin may come from a small mandible or a short chin point. EU chooses between double jaw surgery, mandible-only surgery or a chin advancement according to the diagnosis.
Mandible-only surgery (하악수술)
For patients whose bite and profile problem lies mainly in the lower jaw, only the mandible is repositioned, narrowing the scope of surgery compared with a two-jaw operation.
Frequently asked questions
- Is orthodontics always needed before surgery at EU?
- Not always. EU uses both orthodontics-first and surgery-first (선수술) protocols, chosen from each patient's occlusal and skeletal analysis, as explained in its own video on the topic.
- How long is the hospital stay?
- EU runs an inpatient management system with real-time monitoring by trained staff. The length of stay depends on the technique — IVRO and SSRO differ by two to three days — and should be confirmed at consultation.
