It's been about 2 years since OOO had a square jaw and masseter resection behind the ear. The result was unsuccessful, the unsuccessful being the result of quite a bit of negligence. I didn't know it until now, but if the front jaw has developed, it's more effective if you put it in your mouth. However, the director there did not explain the limitations of the surgical method and confidently explained that the entire chin would be neatly shaved, but the result was an uneven shape with less sharp front chin. What's even more ridiculous here is that the left and right are so different. One side cuts too much, and the other side has little change as if they stopped doing it . The length of the base of the ear is different. Both bones and muscles are equal. After all this, he calmly explains that the operation went well, but now that I think about it, I feel that it is great that I can't objectively grasp one's own abilities. It wasn't that noticeable to others, but it wasn't worth a few million won at all. It's so outrageous to have a professional get paid more than anything else and let them do it like that.
