The time for the mandibular angle plastic surgery to reduce swelling is 2 weeks, that is, half a month. Therefore, mandibular angle plastic surgery should have at least half a month's rest time, and you can open your mouth freely three weeks after surgery, but you may still feel a little uncomfortable. It will be back to normal in 60 days. At the same time, the best effect of mandibular angle plastic surgery will appear after 6 months. I recommend a Korean plastic surgery hospital, a Deya plastic surgery hospital in Korea. You can visit the Chinese official website of Yideya Plastic Surgery Hospital for consultation.
