Not expensive. Oral plastic surgery is a mature operation in Korean medical plastic surgery. In the formal medical plastic surgery, it is carried out according to clinical technical specifications, and the risk is small. The so-called complications (bleeding, infection, asymmetry and facial nerve injury) have been rare in recent years. This asymmetry after operation is mainly caused by doctors supplementing less tissue or removing more tissue during the operation.

During the operation, the two sides should be compared repeatedly, and the amount of supplement or resection should be carefully estimated and judged before the incision can be closed and bandaged. Once complications occur, doctors can take corresponding corrective measures to remedy them three months after operation, which has little effect on the cosmetic effect.
