Double jaw surgery

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.

Who it suits

Skeletal protruding jaw, receding chin or facial asymmetry
Long face, anterior open bite or a gummy smile
Severe mouth protrusion beyond orthodontics or ASO alone

Technique highlights

Operated by two board-certified oral & maxillofacial co-directors
Planned on 3D CT with combined digital and model analysis
Coordinated with the hospital's own orthodontist before and after surgery
Inpatient management system with a resident anaesthesiologist

Surgical steps

3D CT and radiographs with combined occlusal and facial proportion analysis
Surgical simulation to set how far each jaw moves
A patient-specific wafer produced by the in-house laboratory
Intra-oral osteotomy of both jaws with plate and screw fixation
Inpatient recovery with continuous staff monitoring

Recovery & aftercare

Water from 6–8 hours; smooth liquid food from the next day
Sleep with the head above heart level in week one to limit swelling and ease breathing
Compression face band for about two weeks and antiseptic rinses three times a day for two weeks
Follow-ups at one week, two weeks and one month, with two weeks of laser de-swelling care

Risks & things to consider

Old blood may drain from the mouth or nose for the first few days, and in some patients for up to four weeks
General anaesthesia is required, so health screening and fasting rules apply
Skipping the planned post-operative orthodontics can leave the bite unsettled and the result unstable

Frequently asked questions

How often must you return after double jaw surgery?

EU asks patients to return one week, two weeks and one month after discharge; IVRO and SSRO schedules differ by two to three days, and two weeks of laser care is provided.

What if breathing feels difficult after surgery?

EU explains that swollen oral and nasal mucosa makes breathing uncomfortable; staff monitor patients continuously while admitted, and a nasal spray is prescribed for use at home.
