Who is suitable for orthognathic surgery? At what age is it suitable for orthognathic surgery?

Orthognathic surgery is a relatively major operation, which mainly improves protruding mouth and ugly face shape. It can usually be performed after the bones are completely closed. Do not have this surgery at a very young age.

Who is suitable for orthognathic surgery?

1. This surgery is suitable for those with enlarged mandibular angle, eversion, and obvious "square face" or "trapezoidal face".

2. This surgery is suitable for people with a too long philtrum: As people age, their philtrum gradually becomes longer and looks old. You can consider a philtrum shortening surgery to make yourself look younger.

3. This technique can be used to correct imperfect face shapes such as square face and fat face. People with square face and fat face can create a perfect oval face shape through this technique.

What is the appropriate age for orthognathic surgery?

Generally, girls after the age of 16 and boys after the age of 18 can also observe bone age by taking wrist joint X-rays. If the X-ray shows that the epiphysis has closed, it can be judged that the growth and development have stopped, and orthognathic surgery can be performed at this time. Care should be taken to avoid premature surgery to prevent new deformities from occurring as the child grows and develops.

Are there any side effects of orthognathic surgery?

1. Respiratory tract obstruction: Respiratory tract obstruction is mostly caused by blockage of secretions after orthognathic surgery. After orthognathic surgery, the nasal mucosa becomes edematous and bleeding, which makes the nasal airway smaller. The drainage of the surgical site is not smooth, forming a hematoma at the floor of the mouth, causing ventilation obstruction.

2. Necrosis of teeth and alveolar bone: Necrosis of teeth and alveolar bone mainly occurs in the teeth and periodontal tissues on both sides of the interdental bone incision and the osteotomy line, especially after multiple bone segment incision in the maxilla.

3. Infection: The chance of infection after orthognathic surgery is about 3%. Orthognathic surgery is performed in the mouth. If the oral hygiene is poor after the surgery and the lifestyle is abnormal, the chance of infection will increase.

How long does orthognathic surgery take?

General orthodontic-orthognathic combined treatment is divided into three stages: preoperative orthodontics - orthognathic surgery - postoperative orthodontics. Preoperative orthodontic treatment takes about 8-12 months, and orthodontic treatment for another 6-12 months is performed three months after orthognathic surgery.

Orthognathic surgery achieves the purpose of surgery by moving the jaw. Although the surgery has certain risks, with the mature application of digital technology in the field of oral and maxillofacial surgery, the use of digital surgical auxiliary design before surgery can improve the predictability and accuracy of surgery, and greatly reduce the risk of surgery. For patients with bone-induced malocclusion with relatively neat teeth and good occlusion, surgery can be performed first without preoperative orthodontics. After preoperative planning with the help of digital surgical auxiliary design, orthognathic surgery can be performed directly, and then postoperative orthodontics can be performed. The time for postoperative orthodontics is shortened to 3-6 months due to the role of digital surgical auxiliary design.
