I did it in Shanghai last year. Jaw plastic surgery is performed under general anesthesia. No pain was felt during the operation. Generally, mandibular surgery needs hospitalization observation 1 to 2 days, and basically recovers in 7- 10 days, and the effect can be about 80%-90%. This is because the swelling of soft tissue has not completely subsided. After that, it became more and more obvious not to eat hard food for a month. It takes about 1-3 months to fully recover, but this also varies from person to person.
