Double jaw surgery

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.

Who it suits

Mandibular protrusion with a normal maxilla
Retrusion from an under-developed mandible

Technique highlights

A smaller operation and shorter recovery than two-jaw surgery
IVRO or SSRO selected according to the diagnosis

Surgical steps

Confirming the maxilla is correctly positioned
Choosing the osteotomy technique for the occlusal pattern
Surgery and fixation in the new position

Recovery & aftercare

EU notes that IVRO and SSRO follow-up schedules differ by about two to three days

Risks & things to consider

If the maxilla is also involved, mandible-only surgery may not be sufficient

Frequently asked questions

How does it differ from double jaw surgery?

EU explains that mandibular surgery moves only the lower jaw and suits patients whose maxilla is already well positioned, while two-jaw surgery is used when both need adjusting.
