Facial contouring mainly involves the shaping of the facial skeleton. The facial shape is determined by the structure of the facial skeletal framework. The long face, round face, square face, melon face, etc. that we usually see are all due to the three-dimensional distribution and arrangement of the skeletal structure and form their own unique facial shape. By changing the position of the bones, the facial shape can be changed, such as from square face to melon face. With the development of modern craniomaxillofacial surgery technology, the entire head and facial bones can be operated and reset, such as the frontal bone, orbit, nasal bone, maxilla, mandible, zygomatic bone, etc. These bones constitute the framework system of the face, and can fundamentally change the facial shape after repositioning. Commonly used facial contour plastic surgery: 1, forehead plastic: forehead narrow, not full, using filling 2, arch plastic: low arch, using filling methods 3, temporal plastic: temporal depression, not full, using filling 4, zygomatic bone is too high: zygomatic bone narrowing reduction surgery 5, zygomatic bone low flat: implant, zygomatic bone widening surgery, traction into bone 6, maxillary protrusion (buck teeth) / maxillary recession (upper lip deflated) 7 7, mandibular protrusion (pouched teeth, bungee) / mandibular recession (small jaw 8, facial oblique deformity: 9, jaw angle hypertrophy: jaw angle curved osteotomy, bone grinding, or bone plate removal jaw angle defect: jaw angle reconstruction 10, chin: chin horizontal osteotomy or prosthesis implantation; if the chin hypertrophy, the implementation of partial amputation, trimming These procedures basically cover most of the facial bone plastic surgery, facial contour All of the bones involved in facial contouring can be moved and reconstructed according to the surgical design. Some special cases involve cranial surgery, which may require cranial osteotomy traction, osteotomy of early closure of the suture, narrowing of the widened orbital distance, etc.
