About this procedure
A surgery that corrects malocclusion and facial asymmetry of the upper jaw (maxilla) and lower jaw (mandible). It is performed not only for aesthetic purposes but also to improve chewing and occlusal function, often in conjunction with dental (oral and maxillofacial surgery).
Who it's for
Individuals with malocclusion, facial asymmetry, and protruding teeth.
Effect
Aims to improve facial balance and occlusion, with results varying by individual.
How long results last

Anesthesia
General anesthesia
Downtime
Swelling significantly reduces within 1 week to 1 month, but the effects on jawline, such as square jaw, are reported to manifest about 70% at 1 month, about 90% at 3 months, and 100% at 6 months (staged manifestation).
Hospital stay
3-7 days (major surgery under general anesthesia, based on data)
Swelling timeline
1 week to 1 month — basic swelling subsides, 1 month — about 70% of the effect manifests, 3 months — about 90%, 6 months — 100% manifests.
