Mandibular angle plastic surgery is to choose a suitable surgical plan according to everyone's detailed situation, stop cutting off the hypertrophic mandibular margin and part of the masseter muscle, and perform the operation in the mouth without leaving any scars after operation. This is a high-risk operation. I suggest you go to the hospital for consultation in person according to your own situation, and you can also look at the cases of experts. Don't listen to the internet saying that only experienced doctors can make a safe surgical plan for you before operation, and you can try to avoid touching during operation. Moreover, adverse reactions can be found and handled in time during the operation, which improves the safety of the operation.
