I received nerve block masseter muscle reduction surgery in Gangnam two years ago .. I got it because I wanted a v-line for cosmetic purposes. I thought it was a very simple procedure because I heard that even children and the elderly do it, but I really felt the pain of pinching my nerves as if the anesthesia was less. I think it's the same.. I remember screaming because it was really painful... ㅜㅜ At first, I had to put up with a face like Dooly for a few weeks. However, when the swelling goes down , it seems that the v-line is maintained even if the square jaw is not Botox . Have you lost weight? I also hear this... Hahaha But when I open my mouth, I feel that I can't open it as wide as before (my personal feeling).
