The bone-grinding and face-lifting operation in the New Facial Sculpture Center of Shengjia is to chisel away some bones in the mandibular angle with instruments, thus narrowing the facial contour, improving the face shape and leaving no scars, just like being born. Advanced anesthesia technology is used to grind bones and thin face, so the whole operation process is painless and patients can enjoy the operation process unconsciously. In addition, the operating rooms used in the operation are all standard floors, which are ultra-clean and the safety of the operation is thickened. Therefore, the safety of bone grinding surgery is very high.
