Make an incision on the inner side of the mouth near the mandibular angle or cheekbone, pull the whole facial skin and muscles 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.

Because of its small trauma and less bleeding, applying bone wax to the incision of bone can stop bleeding and help the bone recover itself.

The skeletal support structure of masticatory muscle changed after operation, and the treatment was carried out according to the hypertrophy of masticatory muscle. If it is too large, some muscles in the back can be removed to adapt to the new bone structure.

When closing the wound, place a drainage tube to remove the congestion. Generally, the drainage tube can be removed on the second day after operation. Face-changing surgery includes a variety of surgical items, including mandibular angle plastic surgery. A few days before this plastic surgery, we should cooperate with the doctor to do the following things:

First of all, we should start a healthy lifestyle, quit smoking 2-6 weeks before face-lifting surgery, reduce the amount of drinking to almost no alcohol, do not use sugar, tea and coffee, and limit the use of processed foods and dairy products; Be sure to tell your doctor whether you are taking any medication (with or without a prescription).

You can take some vitamins or supplement your diet before face-changing surgery to improve your healing ability. Vitamin K, starting from 3-5 days before operation, 5 mg per day can reduce skin cyanosis caused by postoperative bleeding.

The night before face-changing surgery, take a bath easily and cleanly, and quickly after 12 pm. If it is the operation in the afternoon of the next day, start fasting the next morning.

Only by doing these preoperative preparations can we better embark on the transformation journey of changing our face! 1, organic diseases without vital organs, such as heart disease, hepatitis, nephritis, pneumonia and other diseases;

2. No source of oral infection, such as periodontitis and oral ulcer;

3. Routine health checks such as blood routine, urine routine, chest X-ray and electrocardiogram were performed before operation;

4. Check the "curved section of mandible" and lateral X-ray film of mandible. If we can master the correct nursing methods after the operation, it can also help us improve the operation effect:

1. First of all, care should be paid attention to: the incision made in our operation is the focus of our care. Because the skin has been damaged, we must keep the skin clean during nursing to avoid bacterial infection during our recovery.

Secondly, we should pay attention to nursing the swelling of our surgical site. Because swelling is a normal phenomenon after our treatment, it will disappear with the recovery of our wounds. If you feel that your swelling disappears slowly, we can use ice to help you reduce the swelling quickly after the operation.

3, pay attention to diet is also very important in our maintenance and care, because the food with more irritation will affect the skin healing at our incision, so in our recovery process, we should pay attention to avoid eating irritating food and eat more nutritious and light food, which can help us recover quickly. Ice must be applied every day for the first three days after operation, and you can only drink cold liquid food to avoid infection. You can't eat soft food until the wound heals. If you want to return to a normal diet, you'd better eat liquid food, which will help shorten the recovery time of face-changing surgery.

More rest is an important link that we must not ignore when we recover. Adequate rest can accelerate the growth of our skin and greatly shorten our recovery time.
