In reality, people often find that some people’s facial features are not very outstanding when examined alone, but combined with the face is a very beautiful face, while some people’s features alone seem to be very good, but combined with the facial shape is not beautiful. The reason for this is that the differences in facial contours influence people’s aesthetic judgment. Facial contour reshaping is a hot direction for plastic surgery in recent years, and the number of patients seeking treatment is increasing. Facial contour remodeling in a broad sense refers to the use of surgical or interventional treatment methods, while according to the principles of facial aesthetics on the face of the bone and soft tissue to increase, decrease, and shape, to change the shape of the facial contour, to improve the facial aesthetics of the means. In a narrow sense, it refers to the technique of using surgical procedures such as bone grinding and osteotomy to trim and reconstruct the bony tissues of the head and face. Facial contour from the frontal view mainly refers to the ratio of the width of the upper, middle and lower parts of the head. From the side view, it mainly refers to the degree of difference between the frontal, facial and chin forms compared to the normal X-ray cephalometric lines. Facial profile aesthetics is affected by many factors, including: the fullness of the face, the ratio of the length of the face to the height, the degree of obesity of the patient, the degree of skin laxity, the size of the frontal bone development and the fullness of the temporal fossa, etc. It is also necessary to consider the patient’s subjective requirements, aesthetics, cultural quality, occupation, age, psychology and other factors. The facial contour line is the line of the high point of the craniofacial profile at all angles. The beauty of the facial contour is mainly determined by the structure and shape of the bones and soft tissues of the face, especially the structure and shape of the bones. The main facial contour lines include: the arch of the eyebrows, the tip of the nose, the back of the nose, the zygomatic arch of the cheekbone, the angle of the jaw, the lower edge of the mandible and the chin. Facial contour remodeling sites: forehead, zygomatic bone zygomatic arch, maxilla, mandible, mandibular angle area, chin The main procedures for facial contour remodeling include: osteotomy, bone grinding and filling, i.e. chinplasty, facial skew correction, mandibular angle hypertrophy correction, zygomatic bone zygomatic arch, soft tissue filling of the forehead, etc. Among them, chinoplasty includes: horizontal osteotomy chinoplasty, chin autologous bone implantation, chin prosthesis implantation. Facial deviation revision surgery includes: mandibular inferior margin osteotomy, mandibular decortication, mandibular ascending sagittal split osteotomy, maxillary Lefort type I osteotomy, prosthesis implantation, etc. Mandibular angle hypertrophy correction includes: mandibular angle osteotomy, mandibular decortication, mandibular bone outer plate grinding. Zygomatic arch surgery includes: high zygomatic arch complex grinding and lowering surgery, high zygomatic arch L-shaped osteotomy internal thrusting + preauricular incision zygomatic arch root chiseling internal thrusting surgery, zygomatic arch prosthesis implantation elevation surgery. Nowadays, with the maturity of craniomaxillofacial surgery, orthognathic surgery and microsurgery, almost all craniofacial bones from the skull to the mandible can be cut, divided and reshaped.
