6. After zygomatic grinding, routine facial photos were taken for comparison and curative effect evaluation. If possible, you can do three-dimensional skull CT. X-ray film of maxilla can be taken to understand the development degree of maxillary sinus. In some cases, a facial model should be taken to accurately measure the amount of bone resection of cheekbones.

7. Rinse your mouth with compound borax solution 3 days before cheekbone grinding, and clean your mouth if necessary. If the external incision needs to use 1: 1000 new gel defoaming head.

4. Processing method and process

Method 1: The operation method of anterior internal fracture of zygomatic bone: cut the prominent zygomatic bone, remove a small piece of bone to be reset, fold the remaining zygomatic bone inward, and then fix it with bone nails, and keep the zygomatic arch intact.

Suitable for face: suitable for people whose face is not too wide but whose front is prominent.

Advantages of the operation: the operation incision is completely carried out in the oral cavity, and there is no incision in appearance, which does not affect the appearance.

Difficulties in operation: because the zygomatic arch has not changed, the reduction degree is limited and not obvious.

Method 2: Operation of posterior medial zygomatic fracture.

Operation method: use the method of grinding bone to appropriately reduce the protruding volume of cheekbone and keep it in its original position; The incision is in front of the ear, breaking the zygomatic arch and folding inward.

Suitable for face: the face is wide and the temples have a certain sense of depression.

Advantages of the operation: This method can effectively change the position of the zygomatic arch, and the zygomatic process has also been properly adjusted, so the face shape can be obviously narrowed.

Difficulties in operation: This operation is complicated, and there are two hidden incisions in the mouth and in front of the ear.

Method 3: zygomatic adduction surgery

Surgical methods: zygomatic process and zygomatic arch were interrupted, the bone part that needed to be reset was removed, and the whole zygomatic bone moved inward and then reassembled.

Suitable for face type: the face with wide and prominent front side.

Advantages of surgery: this is the most mainstream method at present, with a large reduction of cheeks and obvious visual effects; The incision is in the mouth, which does not affect the appearance.

Difficulties in operation: The technology is quite complicated, and it needs a doctor with very rich clinical experience to complete it safely.

5. curative effect

Although grinding cheekbones is the most direct and effective method to change face shape at present, it is not obvious immediately after operation. Because there is a swelling period of the wound after zygomatic plastic surgery, the change of facial width is not obvious from the appearance, and some will even be wider. This period usually lasts for half a month to about a month. As the swelling subsides, the surgical effect will gradually appear one to three months after operation.

6. Complications

1. The most important complication is the injury of temporal branch of facial nerve, which leads to drooping eyebrows and "sad face". These complications will greatly affect the quality of life of beauty seekers.

2. There is also a very dangerous complication-nerve injury.

3. Hypertrophy of mandibular angle (square face becomes melon-shaped face) may damage mandibular marginal branch of facial nerve through extraoral approach.

4, leading to paralysis of the upper and middle part of the platysma, descending muscles and descending muscles, facial deformation (especially when facial expressions such as smiles, etc.). ) and asymmetry.

7. Rehabilitation and care

1. Patients are required to stay in hospital for 3-5 days after operation.

2. Rinse your mouth with mouthwash 6 hours after operation until the stitches are removed.

3. Don't do facial beauty massage or rub the operation area within three months.

4. After operation, the hood should be bandaged with pressure for 5 ~ 7 days. If there are no special circumstances, it can't be disassembled halfway. If it is disassembled, it should be bandaged in time. Pay attention to check for broken skin. If a drainage strip is placed in an oral wound, it should be taken out 48 hours after the operation.

5. Take out stitches 7 days after operation, eat less spicy food and try to eat semi-liquid food.

6. Eat liquid food on the fifth day after operation, and try to avoid biting hard objects within three months.

8. Risk and prevention

1, the temporal branch of the facial nerve was injured, resulting in drooping eyebrows and a' sad face'. These complications will greatly affect the quality of life of beauty seekers.

2. There is also a very dangerous complication of facial and neck skin incision: nerve injury.

3. Hypertrophy of mandibular angle (square face becomes melon-shaped face) may damage mandibular marginal branch of facial nerve through extraoral approach.

4, leading to paralysis of the upper and middle part of the platysma, descending muscles and descending muscles, facial deformation (especially when facial expressions such as smiles, etc.). ) and asymmetry.

9. Physiology and Aesthetics

Many people think that grinding the cheekbones can achieve a perfect face shape, but it is actually impossible. Because the face shape is not only influenced by cheekbones and mandibles, but also by the whole skull structure, it is obviously unrealistic to simply cut off the mandible or cheekbones and only change some parts. To achieve the standard oval face, the whole skull structure must be reorganized.
