CCTV “Into Science” has a program entitled “Half Face Girl”, almost all people who have watched this program will be stunned by the main character Li Yan’s severely atrophied left face, in the girl’s sorry at the same time, not only will ask “what disease is the little girl? ” In fact, for plastic surgeons, the girl Li Yan is suffering from hemifacial atrophy, is a slow course, soft tissue or muscle, bone progressive side atrophy disease, belongs to the plastic surgery in the craniofacial surgery category. However, as a general population, the understanding of craniofacial surgery is far from as popular as the understanding of digestive diseases, infectious diseases, the most contact or just some contact is only the jaw angle or chin cosmetic surgery. In fact, the earliest purpose of this surgery is to create a new technology for craniofacial defects and deformities caused by craniofacial congenital deformities and traumatic car accidents, which tended to mature in the late twentieth century. In 1977, a group of scholars in China, led by academician Zhang Jiesheng, completed the first case of craniofacial surgery, a combined intracranial and extracranial approach to correct orbital spacing widening. Thus, the development of craniofacial surgery in China began. The creation and development of this discipline has led to an unprecedented satisfactory outcome for severe and complex congenital or acquired craniofacial anomalies. Craniofacial surgery mainly through the plastic sculpture of craniomaxillofacial skeletal framework to achieve the purpose of changing the facial appearance, so that patients with craniofacial deformities to obtain normal appearance, the scope of treatment includes: 1, orbital spacing widening; 2, craniofacial osteogenesis imperfecta; 3, craniofacial cleft; 4, Treacher-Collins syndrome and related deformities; 5, craniofacial asymmetric deformities; 6, post-traumatic or tumor resection craniofacial deformities From this, we can roughly see that the scope of craniofacial surgery is mostly associated with craniofacial deformities, craniofacial cosmetic surgery is only a branch of craniofacial surgery.
