Jaw bone grinding process

In pursuit of beauty, many women undergo surgery on their bodies, such as double eyelid surgery, nose augmentation, liposuction, cheekbone grinding, etc. There are always certain risks in any surgery. Plastic surgery usually requires anesthesia for the patient, and if the dosage is inappropriate, it may lead to serious consequences. Jib bone grinding surgery also has certain risks, so it is recommended that you go to a regular hospital for it. The following is an introduction to the process of jawbone grinding.

1. Cheek Grinding and Bone Reduction Process

(I) What is cheek bone reduction surgery?

Cheekbone grinding and bone shaving is a plastic surgery that involves making an incision inside the mouth near the mandibular angle, removing both the inner and outer layers of the excess mandibular bone, and then grinding and thinning the edge of the remaining outer plate of the mandibular bone. In plastic surgery, the facial skin and muscles are turned over from inside the mouth, the muscles are separated from the periosteum, and the bone part that needs to be sharpened is exposed. According to the designed amount of osteotomy, the osteotomy line is drawn, and finally a long-handled oscillating saw is used to remove the mandibular angle along the osteotomy line. Generally, an arc-shaped removal of 3 to 4 cm in length and 1 to 2 cm in height can be performed to smooth the edges after osteotomy. Achieve the effect of face slimming.

(II) What is the detailed process of cheek bone reduction surgery?

The cheek grinding and bone cutting surgery is to make an incision on the inside of the mouth near the mandibular angle, turn over the facial skin and muscles from the inside of the mouth, separate the muscles and periosteum, expose the bone part that needs to be ground, and draw the osteotomy line according to the designed osteotomy amount; use a long-handled oscillating saw to cut the mandibular angle along the osteotomy line. Generally, an arc-shaped cut of 3 to 4 cm long and 1 to 2 cm high can be made to smooth the edges after osteotomy. This is the procedure of the operation.

Experts say that many people today are not satisfied with their face shape, and most people want to modify their face shape by glancing down and reducing bones. Therefore, there are many issues regarding price. The prices for cheek and bone reduction are different for different face shapes. Common face shapes can be divided into: round face (protruding cheekbones), square face (protruding mandibular angle), bulge face (protruding chin or front end of mandible), etc.

(III) Technical challenges of cheek grinding and bone cutting

During the mandibular angle bone grinding surgery, in order to make the mandibular angle area easier to expose during the surgery and reduce the possibility of accidental damage to blood vessels due to unclear vision, it is necessary to use tissue scissors to cut off part of the masseter tendon attached to the mandibular angle area.

This is a severe challenge to the doctor's technical level. Mandibular angle bone grinding and face slimming surgery for the treatment of square cheek deformity is limited to grinding the mandibular angle bone except for the turned-over mandibular angle. It is advisable to grind only the outer plate of the mandibular platform. If the outer plate is completely removed, a large area of ​​mandibular cancellous bone will be exposed, osteoblasts will overflow, and new bone will be formed, resulting in poor postoperative results.

(IV) What is the effect of cheek bone reduction surgery?

What we usually call "cheeks" are very close to the mandibular angle, and sometimes they can be equated. Therefore, the surgery known in medicine as cheek bone reduction surgery is a surgery to solve the problem of mandibular angle.

Experts say that the cheek grinding and bone cutting surgery is to make an incision on the inside of the mouth near the mandibular angle, turn over the facial skin and muscles from the inside of the mouth, separate the muscles and periosteum, expose the bone part that needs cheek grinding and bone cutting surgery, and draw the osteotomy line according to the designed osteotomy amount; use a long-handled oscillating saw to cut the mandibular angle along the osteotomy line, generally, the arc-shaped cut can be made in an area of ​​3 to 4 cm long and 1 to 2 cm high, and the edges and corners after osteotomy can be smoothed.

The effect of cheek bone reduction surgery: If the patient's cheeks are relatively enlarged, part of the inner masseter muscle can be removed at the same time, or part of the buccal fat pad can be removed by slightly separating it to the outside. During cheek grinding and bone cutting surgery, attention should be paid to protecting nerves and blood vessels and ensuring symmetry of osteotomy. The cheek bone reduction surgery is to completely remove the inner and outer layers of the excess mandibular bone, and then continue to grind and thin the edges of the remaining outer plate of the mandibular bone. It can fundamentally solve various serious problems of wide mandibular bones and easily achieve a significant narrowing of the appearance of both sides of the face.

2. Does it hurt to grind your cheeks and cut your bones?

(I) People who are suitable for cheek bone reduction surgery

1. Common face shapes that require cheekbone reduction and bone shaving can be divided into: round face (protruding cheekbones), square face (protruding mandibular angle), and bulge face (protruding chin or front end of mandible), etc.

2. The cheekbone grinding surgery is suitable for patients with mandibular angle hypertrophy. Mandibular angle hypertrophy is usually bilateral, but unilateral hypertrophy is not uncommon.

3. However, not every square face needs cheek grinding and bone shaving. Muscular square faces can be injected with botulinum toxin. People can check for themselves by pressing their hands on the jawbone, repeatedly clenching their teeth and then relaxing. The protruding dots are the muscles. If the fluctuation is more than 2 cm, it is the muscle hypertrophy type, which can be improved with botulinum toxin. If it is less than 2 cm, it is the bone type, which can only be changed with cheekbone shaving surgery.

(II) Precautions for cheek bone reduction surgery

(1) Before cheek bone reduction surgery

1. Patients who suffer from hypertension and diabetes should inform their doctors of their conditions in detail during the initial consultation so that the doctor can confirm the surgical plan.

2. Before the bone grinding and face slimming surgery, make sure you are in good health and have no infectious diseases or other physical inflammations.

3. Do not take medications containing aspirin within two weeks before the bone grinding and face slimming surgery, as aspirin can reduce the function of platelet coagulation.

(2) After cheek bone reduction surgery

1. Choose a reasonable diet after cheek grinding and bone reduction surgery. The pain will be more obvious on the day of surgery, and the pain symptoms will generally disappear after two weeks or a month. The most common problems after surgery are bleeding and infection. Take bone cutting surgery as an example. If you want to avoid bleeding or infection, you must apply ice every day for the first three days after the operation and can only drink cold liquid food. You can only eat soft food after you are sure the wound has healed. If you want to resume your normal diet, you have to wait at least three weeks.

2. Don’t have too high expectations. Many people think that they can achieve the perfect face shape they imagine through "bone grinding", but in fact it is impossible. Because the face shape is affected not only by the cheekbones and mandibles, but also by the overall skull structure. Simply reducing the jawbone or cheekbones can only bring about partial changes. If you want to achieve a standard oval face, you have to reorganize the entire skull structure, but this is obviously impractical.

3. Cheekbone and bone reduction surgery does not have immediate effects. Although bone reduction surgery is currently the most direct and effective way to change face shape, the results cannot be seen immediately after the surgery. Because there will be a swelling period of the wound after the operation, the change in facial width is not obvious from the appearance, and in some cases it may even be wider. This period generally lasts about 3 months. As the swelling subsides, the results of the surgery will gradually become apparent.

(III) Sequelae of cheek grinding and bone reduction

1. Distortion of facial muscles

The side effects of zygomatic bone grinding can damage the sensory nerves and cause numbness. Damage to the facial nerves will affect the muscle movements of the face, necessitating a ban on zygomatic bone grinding and face-slimming repair.

2. Joint dislocation

Whether it is mandibular surgery or zygomatic bone surgery, the temporal joint will be affected. It is located on all four sides of the temple and is the position where the chin is usually hung. Therefore, during the operation, the doctor has to hold the patient's chin firmly in order to maintain tension in the temporal joint. If he is not careful, it may cause dislocation of the joint, which is often referred to as "dropping the jaw" and other sequelae.

3. Left-right asymmetry

Let's first understand the causes of the sequelae of cheek grinding and bone shaving. During the operation, it is impossible for the doctor to accurately calculate the width of the removed (grinded) bones, and the human face itself is not relatively symmetrical. If the doctor's skills are not up to standard or he is careless, it will lead to an increase in the asymmetry of the width of the two sides of the face, causing the sequelae of cheek grinding and bone shaving.

4. Hematoma after zygomatic bone grinding

Any surgery involves a large number of blood vessels and nerves. Even if the bleeding is fully stopped, it is easy to have side effects such as bleeding after zygomatic bone grinding. Only zygomatic bone grinding and face slimming repair can solve this problem. Therefore, during surgery, the doctor will usually place a drainage tube to drain the blood from the wound.

(IV) Risks of bone cutting surgery

Many people modify their facial bones to change their face shape. There are two ways to modify bones. One is grinding the bones, and the other is using a professional medical chisel to remove part of the bone. The latter method is no longer used clinically. If the patient has enlarged cheeks, part of the inner masseter muscle will be removed, or the cheek fat pad will be slightly separated and removed from the outside. In this process, it is inevitable that the protection of nerves and blood vessels and asymmetry of osteotomy will occur during the cheek grinding and bone cutting surgery. Bone grinding surgery may cause heavy bleeding or nerve damage, resulting in facial numbness or even facial paralysis.

Bulging cheeks make the face look wide and fat. If you want to slim down your face, cheek shaving and bone reduction are the best options. But are there any risks in the surgery? Since this method of changing face shape is treated through surgery, using instruments to remove excess cheekbones, people will worry about the safety of the surgery. Regarding this issue, let's listen to what authoritative experts have to say about it.

Regarding the risks of surgery, most doctors understand it, because health is the best state of life. Cheek grinding and bone shaving for face slimming is done by making an incision on the inside of the mouth near the mandibular angle. The facial skin and muscles are turned over from the inside of the mouth, the muscles are separated from the periosteum, and the bone that needs to be cut is exposed. According to the designed amount of bone cutting, the osteotomy line is drawn; a long-handled oscillating saw is used to cut the mandibular angle along the osteotomy line. Generally, an arc-shaped cut of 3 to 4 cm in length and 1 to 2 cm in height can be made to smooth the edges and corners after osteotomy. The amount of cutting will affect the harvest, so it must be done in moderation. The entire surgical process is performed under anesthesia, so there is little pain during cheek and bone reduction. However, there won’t be much risk if it is handled by a professional doctor.

But you need to be careful to sew it up from the mouth after finishing. Afterwards, it will swell up like a pig's head and it will take a long time to reduce the inflammation. Will it hurt? Experts say that bones do not feel pain because they have no sensory nerves. Zygomatic bone reduction surgery is a surgery to remove protruding cheekbones. It is less painful than other surgeries. However, if the surgical operation is performed improperly and the periosteum, muscle or other tissues are damaged, there will be a certain amount of pain.
