This kind of operation does not need to remove any bone, but only needs to use a professional grinding tool to thin the outer layer of mandibular angle bone, thus reducing the width. But don't treat bone grinding surgery as a simple "subtraction". The thickness of the mandible that can be worn off is very limited, only 5-6 mm at most.

Many people think that it is impossible to achieve a perfect face shape by "grinding bones". Because the face shape is not only affected by cheekbones and mandibles, but also the whole skull structure. Simple removal of mandible or zygomatic bone can only partially change. If the standard oval face is very demanding, the whole skull structure will be reorganized, but this is obviously unrealistic.

Although these contents are plagiarized, you really want to do them. I recommend you to have cosmetic surgery. I have friends who have had this operation there, and the effect is really good ~
