1. negotiation: the surgeon expresses to the doctor what he wants to reduce and what he wants to achieve. Doctors usually take X-rays or even magnetic resonance before operation to clearly understand the bone structure, and then make suggestions according to personal characteristics to determine the operation method.
2, anesthesia: divided into local anesthesia and general anesthesia.
3. Incision: make an incision near the mandibular angle or zygomatic bone inside the mouth, pull the skin and muscles of the whole face away from the mouth, separate the muscles from the periosteum, and expose the bone parts that need surgery, and then perform bone grinding surgery. Because most of the blood vessels and nerves are in the position where the muscles connect with the skin, the incision is in the mouth, and the instruments are covered during the operation, and the nerves are separated from the muscles, so it is very safe.
4. Hemostasis: Due to less traumatic bleeding, applying bone wax to the incision of the bone can stop bleeding and help the bone recover itself.
5. Masticatory muscle treatment: After the operation, due to the change of the skeletal support structure of the masticatory muscle, it is treated according to the hypertrophy of the masticatory muscle of the operator. If it is too large, some muscles in the back can be removed to adapt to the new bone structure.
6. Suture and drainage: place a drainage tube while suturing the wound to remove congestion. Generally, the drainage tube can be removed on the second day after operation.
7, appropriate pressure dressing: by dressing the face, it can not only play a certain role in hemostasis, but also help to shape the face.
8, surgical recovery: if it is grinding the bone to change the face, generally only need to stay in hospital for one day, after pulling out the drainage tube, you can leave the hospital; For resectable surgery, you will be hospitalized for three days to one week. In this process, the doctor will give the operator the right amount of antibiotics to prevent wound infection; Sometimes it is necessary to inject a small amount of hormones to reduce the degree of facial swelling.
