Abstract
The surgical treatment of jaw deformity is popular now. And demand level of both patients and orthodontists for the surgical treatment is becoming higher. In order to respond to their demands, it is important for oral surgeons to acquire the right diagnostic method and safe and basic surgical technique for orthognathic treatment. Incorrect diagnosis leads incorrect surgical planning, and higher treatment results cannot be obtained without safe and basic technique for orthognathic surgery.
The basic orthognathic surgery are sagittal splitting ramus osteotomy (SSRO) of the mandible and Le Fort Ⅰ osteotomy(LF I) of the maxilla. Though these two osteotomy technique are extremely popular, oral surgeons have to operate anatomically high-risk regions during both of them. In addition, special care for patients' air-way is necessary after orthognathic surgery.
In this review, basic method of surgical planning for dentofacial deformity patients is described first. Then, the basic technique and knacks of two popular osteotomies (SSRO and LF I) are described. The pitfalls and various risks during the two osteotomies are also referred to simultaneously.
