ABSTRACT
Orthognathic surgery became more popular because people are more interested in facial profile changes and are more receptive to surgery. As people seek beauty as well as function in maxillofacial surgery, patient's aesthetic demand becomes higher. Considering these big changes, one of the major reasons is surgery-first orthognathic approach(SFOA), which removes pre-surgical orthodontic treatment. Pre-surgical orthodontic time has been a great barrier to patients in terms of time and social rehabilitation. By SFOA, patients can get surgery as soon as they make up their mind; Patients from abroad can get surgery and get back to their country; They can go back to their work more easily because their occlusion is more acceptable. Surgery first orthognathic approach is still developing in practice and principle. However, as it is based on patient's need, it will play a greater part in the field of orthognathic surgery. Surgery first orthognathic approach together with aesthetic two jaw surgery are expected to change the paradigm in orthognathic surgery.
