I've done it. Many stars have done it. I didn't know about this mandibular plastic surgery until I saw Mei Xing. My mandibular angle is also very big, and I want to become a melon face. I went to Korea for surgery, where the technology and instruments were not as good as those in China. I think my attending doctor told me that the core of mandibular reduction is cortical amputation. Corticotomy is not a simple operation to remove the mandibular angle, but to narrow the mandibles on both sides to a wider area, and the effect can be clearly seen. If you use this method, you don't have to contract the broad masticatory muscles.

Through such an operation, the asymmetric structure of the face can also be coordinated and corrected.
