How to deal with complications of mandibular angle plastic surgery?
1. Hematoma: When the mandibular angle is removed, it may lead to muscle bleeding at the attachment of the masseter muscle, and the bleeding should be strictly stopped during the operation. Drainage tube should be placed and pressure bandaged after operation, and large hematoma should be explored and removed in time.
2. Fracture of condyle: It is a serious complication of mandibular angle osteotomy, which is mostly caused by high osteotomy line, incomplete osteotomy and violent osteotomy with chisel. After the discovery, it was reset in time, and the affected jaw pad continued to be pulled between jaws for 6-8 weeks.
3. Asymmetry: When the surgical method of removing masseter muscle was used in the early stage, bilateral asymmetry was more common. The main reason of asymmetry is that the amount of bone cut on the left and right sides is inconsistent. Careful analysis of the condition before mandibular angle plastic surgery, reasonable design of osteotomy line and bone cutting amount, and careful operation during the operation.
4, closed teeth: when the masseter muscle is partially removed, it is the most serious problem, sometimes lasting for a long time. Care should be taken to stop bleeding during mandibular angle plastic surgery, and ice packs should be placed on both sides of the face after surgery to avoid opening your mouth too wide or yawning. Regular jaw movement helps to avoid spasms. Adjuvant therapy such as alternating hot compress and cold compress can be used.
5. Nerve injury: When mandibular angle osteotomy took the oral approach, the nerves involved in the operation were mainly mental nerve and inferior alveolar nerve. Patients whose osteotomy line exceeds mental foramen are more likely to be injured. In this case, the mental nerve is dissected and carefully protected. Generally speaking, the local sensory disturbance caused by slight injury caused by the traction of instruments on local nerves during operation can gradually return to normal in 3-5 weeks. Tip: if the doctor's technical level is improper, it will produce uneven problems.
