It's been 9 years already. I felt the side effects immediately after 2 weeks after the stitches were removed after the operation. Once you turn your head, you will hear a noise from your chin and your mouth will close. When you close it, the shape of your mouth is weirder than before. Of course, the shape of the lips has also changed. The lower lip is a little bigger. When I went back to the hospital and talked to him, the doctor said he was fine and just left. So I tried not to worry about it. But since about a year ago, as I got older, I felt that the skin on the chin was sagging and it was difficult to close my lower mouth again. If you try to close it forcibly, walnut wrinkles form on your chin. Plastic surgery was no longer reliable, so I went to a university hospital. Konkuk University, Seoul National University. Of course, neither side provided a solution. It's not like I'm going to have to have surgery again, I'll just have to live with it. I'm still very worried about it, and I'm in a very difficult situation mentally because of depression and insomnia. But what worries me more is that the side effects seem to get worse over time. Does anyone have side effects similar to mine? How are you coping with stress? For reference, the hospital where the surgery was performed was ㅇㅇㅇ. The doctor who performed the operation was a popular person who was the director at the time. Taking a picture with Kang Yumi. I can't remember the name.
