You can use 120 jaw angle face-lifting technology, which is one of the four gold medal plastic surgery projects launched by Beijing Contemporary Plastic Surgery Hospital. Orthopedics doctors in our hospital summed up a set of design scheme that completely conforms to the classic temperament of the East according to the classic proportion cases of 100,000 people in the East. We refuse to use osteotomy. In order to make the modified face more natural and the lines more perfect, we adopted an exclusive technology: "right-angle linear reciprocating grinding technology" to make the face exquisite and symmetrical.
