Chin and lower jaw reduction surgery

Chin and jaw reduction surgery is one of the procedures that can be done to make the face more beautiful. In most cultures, especially in Asia, a delicate and prominent oval jaw is considered a beauty face. If a person is unhappy with their square or wide jaw, they may want to undergo surgery to correct the line and create a v-shape in it. Jaw and chin reduction surgery is not a simple and trivial procedure. For this reason, it is important that people know about the surgery, its benefits and complications before making their final decision. This surgery must be performed by the best cosmetic surgeon so that the results are significant. In this article, we are going to provide the information you need in this field.

What is meant by chin and lower jaw reduction surgery?

Chin surgery and generally maxillofacial surgery, or genioplasty, is a surgical procedure to change the shape of the chin and lower jaw, which is done either by using implants or bone surgery. Plastic surgery and other slimming procedures can be done in the lower jaw and chin area to make the person’s face fit. This helps to increase self-confidence of people.

Sometimes the bone in the jaw can be moved forward in an operation called mentoplasty or genioplasty. Also, silicone implants can be used to create more bulge in the chin. Chin and jaw reduction surgery can also be performed in reverse. This means that the bone can be removed to reduce the excessive protrusion of the chin.

Jaw surgery complications and related risks

This operation can be simple to very complex. Many times a chin and chin surgery applicant may choose to use FDA approved fillers and gels as an alternative to chin and mandibular reduction surgery after considering all options, their risks and benefits. These methods last for a shorter period of time. Jaw reduction surgery can help an excessively large lower jaw to harmonize with other facial features.

What is the cause of jaw enlargement?

A large jaw is usually a genetic trait. This means that if a prominent or strong jawline is a common characteristic of a family, then the possibility of having a large or square jaw in their children is also very high. These people are the most important candidates for chin and jaw reduction surgery.

In some cases, an enlarged jaw and chin can be caused by a condition called temporomandibular joint disorder (TMJ). In this disorder, a person may have the habit of chewing his teeth at night, and this will lead to tooth wear. (a disease known as grinding teeth) The cause of this disease is often stress and severe nervous pressure. This repeated pressure on the teeth strengthens and enlarges the person’s jaw muscles and makes it wider. This is somewhat similar to how muscles grow when you train with weights at the gym. Enlargement of jaw muscles is known as muscle hypertrophy. This problem can also be a result of repeated gum chewing or even due to dietary habits such as regular consumption of hard chewing foods that tire the muscles.

What are the types of jaw abnormalities?

Hypertrophy can be unilateral or bilateral, but it is mostly bilateral; It means that the enlargement of the jaw occurs on both sides. This disease is generally asymptomatic and does not cause problems by itself. (Although if it is caused by an underlying condition such as bruxism, the underlying condition can cause other problems and should be treated).

What measures should be taken before surgery?

In order to get the best result, it is necessary to perform various measures before chin and jaw reduction surgery. In the following, we have mentioned the most important things in pre-operative preparation.

  • At least two weeks before the surgery, you should avoid taking drugs such as ibuprofen, aspirin and other drugs that the surgeon mentions.
  • Smoking should be stopped ten to fifteen days before surgery.
  • Probably, the dentist limits the consumption of some foods for his patient.
  • The patient should not eat anything for about ten hours before surgery.

Maxillary stenosis and treatment methods

How is chin and jaw reduction surgery performed?

This procedure takes about one to two hours and is performed under general anesthesia. After the patient is asleep, the surgeon makes small incisions inside his mouth. This will not leave a scar on the face after recovery. Then the doctor removes the extra bones using a laser or micro-scrapers and creates the desired shape for the chin and jaw bone.

To create a better shape, the surgeon may shave the outer part of the bone to create a T incision in the jaw. That is, he cuts the lower jaw bone in a T shape and then welds the two sides of the remaining bones together. This creates a V shape in the chin, which ultimately results in a heart-shaped face.

Also, the surgeon may soften the surface by shaving the lower bone in the chin. This is done to remove the sharp angle of the lower jaw. Choosing the right method for cutting depends on the physics of the patient’s face.

After making the necessary changes, the surgeon closes the incisions. The patient can probably go home a few hours after chin and jaw reduction surgery. But for some time (two to three days) he needs a companion to help him with his work.

But you have to be patient until the wounds, bruises and swelling caused by the operation are completely healed. After that you can see the final result in your jaw. This time is different according to each person’s body.
