Contraindications of mandibular angle plastic surgery mainly include the use of mandibular angle to change bone shape to achieve the purpose of face-lifting, which is only suitable for patients with too wide mandible. For facial obesity caused by fat accumulation or over-developed facial muscles, the effect of this operation is not obvious. If you go to Korea for plastic surgery, you must find a regular hospital, otherwise it will have the same effect as doing it in China. I know a Deya hospital in Korea is very good. A Deya hospital in South Korea has its own special maxillofacial research institute, and its technology in mandibular angle is very mature.
