The risk of jaw angle osteotomy depends on the regularity of the surgery hospital, the professionalism of the surgeon, the patient’s own physical condition and many other factors, so the risk needs to be judged comprehensively. Generally speaking, jaw angle osteotomy surgery has been relatively mature in clinical practice, and the risks can be controlled by regular hospitals, so the risks are relatively low. However, if the surgery is carried out in an irregular place, the risk of surgery is relatively high. The main reason for the risk of mandibular angle osteotomy is that the surgery area has several important blood vessels, such as facial artery, maxillary artery, alveolar artery, and multiple nerves, such as lingual nerve, mandibular nerve, alveolar nerve, facial nerve, etc. If the operation is not done properly, it may cause damage to blood vessels and nerves, intraoperative bleeding and other situations, and even problems such as facial paralysis, slurred speech and masticatory dysfunction in the late recovery period. In addition, there may be anesthesia risk, mandibular fracture, postoperative infection, facial asymmetry, etc. Overall, there are more possible risks, but these risks can generally be avoided in the standardized operation, so it is more important to choose a regular hospital for surgery to reduce the risk of surgery. The surgical process in a regular hospital is strict and standardized, sterilization is in place, the instruments are complete, and the surgeon is skilled, so the surgical risk of jaw angle osteotomy is generally relatively low; however, if you choose an irregular hospital, doctor, etc. to perform the surgery, the risk is relatively large at this time. In addition, if there are structural abnormalities in the patient’s own surgery area, it may increase the difficulty of the surgery. Generally, the difficulty of the surgery can be assessed through pre-operative CT and other examinations to clarify the tissue and organ conditions, so there is no need to worry too much about this aspect. There are certain risks associated with all surgeries, and even if the surgical results are formulated and discussed several times before surgery, there may still be problems such as dissatisfaction with the surgical results, or even bilateral asymmetry, or a more unsatisfactory appearance after osteotomy than before, after the surgery is completed. Therefore, in order to reduce the risk, you should choose a regular and professional medical institution and consult with an experienced surgeon before deciding on the surgery.
