Changing face is a big project in plastic surgery. It is certainly a lie to say that there are no side effects, but side effects can be avoided. As long as you choose a regular plastic surgery hospital, you can minimize the risk. Many people may have the following side effects when changing their faces in informal hospitals.

1, asymmetry: due to the measurement of doctors and other reasons, surgery may lead to bilateral asymmetry after mandibular angle surgery. If there is no serious asymmetry, it can be improved by small side bite or large side injection of botulinum toxin A.

2. Nerve injury: The nerves involved in oral mandibular angle reduction are mainly mental nerve and inferior alveolar nerve, and most of them appear mild numbness due to strain, and gradually recover in 3-5 weeks. If a fracture occurs, it is caused by rough operation or unfamiliar surgical anatomy.

3. Biting teeth: This is the most serious complication when the mandibular angle is reduced and part of the masseter muscle is removed, which mostly disappears about one week after the mandibular angle plastic surgery. Try to avoid opening your mouth and other actions.

4. Hematoma: Hematoma can occur when large blood vessels are damaged during mandibular angle plastic surgery, or the dressing pressure after mandibular angle plastic surgery is not enough, or the drainage after mandibular angle plastic surgery is not good. Pressure bandage again.

5, infection: it is very rare in mandibular angle plastic surgery, the main reason is that the hematoma is not cleared in time. After infection, the wound should be opened in time, cleaned and drained well, and the infection can be controlled in a week or so.
