Experts from Wuhan Wuzhou Plastic Surgery Hospital said that chin plastic's methods include implant, excision and liposuction. Patients with short mandible can be implanted with prosthesis, so that the mandibular angle is elongated and sharp both visually and on the face, and the facial lines of women are soft. Excision can correct jaw deformity by surgery, which is the coordination of facial contour. Liposuction is suitable for middle-aged and elderly women with double chins, which can effectively remove excess fat, make the chin smaller and more delicate, and make the face younger.
