Sequela:
1. Facial asymmetry: During the operation, it is impossible for the doctor to accurately calculate the width of the removed (polished) bone, and the face of the human body itself is not completely symmetrical. If the doctor is unskilled or negligent, the asymmetry of the width on both sides of the face will increase.
Therefore, experienced doctors should not only be familiar with their facial skeletal structure, but also take X-rays (or magnetic vibrations) for operators before operation to clearly understand their unique skeletal structure.
2. Postoperative hematoma: Every operation will involve a lot of blood vessels and nerves. Even if the bleeding is completely stopped, postoperative bleeding is easy to occur. So generally speaking, when surgical suture is performed, the doctor will place a drainage tube to draw out the congestion in the wound.
