I got a lot of messages, so I'm just posting a review here. Today is the 12th day, I had an osteotomy and lost 6mm. Her face was on the longer side under her eyes, but after her chin, it looks longer. I should have taken off about 10mm, but they said I took off 6mm because I was afraid my face would be too long, but it still looks long. I'll sort it by date. There may be individual differences. On the day of surgery - general anesthesia. More swollen tonsils than chin. Days 2-3 - The whole face is swollen. The lips are also very thick. Days 4-5-4. My chin was swollen like a protruding chin. Bruises begin to form on the chin. Days 6-7 - bruising up to the neck and swelling begins to subside. Days 8-9-9 Overall, the swelling on the face has gone down a lot , but there is no feeling in the lower jaw, and it is still difficult to open the mouth. My cheeks are losing a lot of weight because I can’t afford to eat freely. (Looks longer, so.) Day 12 - Mouth opens more or less freely. You can eat rice, but it's not good to chew meat. The lower lip still burns, and the lower jaw also has a slight spatula left,. The lips are the original thickness. So far, I can't feel it. My lower teeth hurt... and my neck hurts . I went out to work on the 5th.. My jaw hurts even more from overdoing it, and I feel like I have a bump on it.. It gets hard. The hospital is near Apgujeong. I did it from the story of ppp facial bones. They say there is only a chin and a nose. In any case, whether it is osteotomy or implant implantation, the short chin makes the face longer. As the swelling goes down, the length is shortened, but it seems to be longer. People with long faces should think carefully. I'm thinking of just leaving it on until my jaw muscles loosen up. You have to think carefully.. If you have chin surgery, your face will feel so different that the balance will be broken, so you don't know if you need to do something else. The cost of jaw osteotomy will be approximately 350-400.
