2. Due to the different aesthetic standards of everyone, the differences of patients' physical conditions and the limitations of current medical technology, the surgical effect may not always meet the requirements of patients, and there may be dissatisfaction or complications; Sometimes patients and their families still don't recognize the success of the operation, so please fully communicate with the doctor before operation to keep a clear understanding of the effect of orthognathic surgery.
3. Orthognathic surgery is usually performed through oral route, but some cases and special circumstances need to be performed through facial incision. There will be scars at the surgical site, and the size of the scars is related to the patient's physique. Most patients' keloid hyperplasia will be relieved in a year or so, but there are also some patients who are at risk of serious keloid formation and difficult to subside.
4. There is swelling and discomfort in the surgical site after operation, and there is a certain recovery period. The recovery time varies with individual's age, physique, surgical site and type (usually 1-3 months, and in some cases it can reach 1 year or more).
5. The two sides of a person's face are not completely symmetrical, and surgery can't make the two sides exactly the same.
6. Surgery is a traumatic treatment, which is risky and generally safe. However, due to the influence of various factors such as surgical methods and individual differences, unexpected situations and complications may occur during and after operation, such as bleeding, infection, accidental fractures, adjacent organs and soft tissue injuries.
7. Orthognathic surgery needs to remove the jaw and re-fix it in the normal position. Titanium plates and nails are needed for fixation, and a small number of people may be at risk of rejection, infection and fracture after operation, and may need to be removed or reoperated.
8. There is a risk of injury to important tissues and organs such as facial nerve, mandibular joint and famous blood vessels during the operation. After operation, there may be symptoms such as unable to lift eyebrows, unable to close eyes, shallow nasolabial groove, numbness of skin in orbital region and lips, facial asymmetry, occlusion and language dysfunction. Those who are light will recover by themselves in 3-6 months, while those who are heavy need further related treatment, and may even not recover at all.
9. Maxillary surgery will change the soft and hard tissue structure of the nose, which may cause deviation of the nasal septum, widening of the alar and change of the height of the nose. You need another operation.
10, orthognathic surgery can change the facial bone structure, and the soft tissue will also change. However, these postoperative appearance changes do not necessarily meet the expectations and requirements of patients and their families before operation, and their postoperative plastic effects are gradually accepted and adapted.
