Square Jaw Reduction

Square jaw reduction is a procedure that reduces a large and developed jaw angle to slim the jawline.

What is Facial Contouring

Facial contouring surgery modifies the shape, width, and ratio of the face by adjusting
the face's bony structure. It can also correct asymmetry and facial disharmony without bite adjustment.

Facial contouring surgery includes cheekbone reduction, square jaw reduction and genioplasty. Depending on the patient’s facial features, and conditions, Facial liposuction, facelift, and sunken cheek correction are the procedures that may be recommended with facial contouring surgery to create a synergistic effect.

Braun doctors are board-certified plastic surgeons in Seoul, South Korea.
They are skilled and experienced doctor with good reputation in Korea.

What is Square Jaw Reduction?

A well-developed square jaw can make the face appear wider and give a more rugged appearance. Square jaw reduction surgery involves contouring the entire jawline, including the prominent and enlarged square jaw. The procedure is typically performed in two stages.

The first step is square jaw resection surgery, which involves directly removing the prominent and enlarged jaw angle. The second step is lateral cortical bone shaving, which reduces the thickness of the jawbone for a more refined contour.

Excessive square jaw resection can lead to an unnatural or artificial appearance. Therefore, preserving a portion of the jaw angle below the ear is crucial. Additionally, lateral cortical bone shaving should be carefully performed to achieve a slim and smooth jawline when viewed from the front

Before vs. After Mouth Corner Square Jaw Surgery

Surgical Procedure

Incision site

There are no visible scars, as the procedure is performed through an incision inside the mouth.

Surgery method

1. The standard square jaw surgery technique

Only a portion of the square jaw is resected, including the
square jaw below the ear.

Lateral cortical bone shaving is performed only on the square
jaw area below the ears.

2. Braun’s square jaw surgery method

Resection of the square jaw to the side of the chin without the formation of a secondary angle.

Lateral cortical bone shaving is performed on the entire jaw bone.

Square jaw muscles(masseter muscles) reduction via high frequency nerve block.

How is Braun's Surgical Method Different from General Surgical Methods?

At Braun Plastic Surgery, lateral cortical shaving is performed not only on the angular part of the square jaw, but
also on the entire area of the salivary glands below the ears and the convex part on the side of the lips This approach avoids the formation of secondary angles while effectively reducing the entire jawline when viewed from the front. As a result, it smooths out uneven contours and creates a slimmer, more defined jawline.

Furthermore, it reduces the square jaw muscles through nerve block, resulting in a smoother and more effectively
reduced jawline.

The 3 Key Considerations for Square Jaw Angle Reduction at Braun Plastic Surgery

There are two major factors that affect the outcome of square jaw reduction surgery. First, the bone must be resected while leaving an appropriate amount of the square jaw below the ears.

If the square jawbone below the ears is excessively resected, it can result in an artificial and unnatural-looking jawline. After evaluating factors such as the degree of jaw development, the position of the ears and lips, gender, ethnicity, and individual preferences, the amount of bone reduction is carefully determined—typically ranging from 1.5 cm to 4 cm.

Second, a slim shape from the frontal view is essential for successful square angle surgery.To achieve such a frontal effect, lateral cortical bone shaving surgery must be done to thin out the outer surface of the jaw bone. Lateral cortical bone shaving is an important and effective method that determines a successful outcome of square jaw reduction depending on which area and how much it is performed.

However, in many cases, lateral cortical bone shaving is not performed due to a lack of awareness about its importance. Even when its significance is recognized, only a minimal amount of shaving is often done, which is insufficient to effectively refine and slim the jawline.

At Braun Plastic Surgery, lateral cortical bone shaving is performed not only on the angular portion of the square jaw, but also along the area beneath the ears near the salivary glands, as well as the convex region beside the lips. This comprehensive approach reduces the entire jawline as seen from the front and smooths out uneven contours, effectively creating a slimmer and more refined appearance. With this technique, the width of the jawbone can be reduced by approximately 3 mm to 10 mm on each side.

Lastly, the jaw line can be even more enhanced by reducing the developed square jaw muscles with a high frequency nerve block.

Skin Sagging Following Square Jaw Surgery and Its Correction

Skin sagging along the sides of the mouth (commonly referred to as jowls) may occur after square jaw surgery. However, it is less likely to happen compared to cheekbone reduction surgery, as the neck muscles naturally provide elastic support to the jawline.

If you have good skin elasticity, minimal facial fat, and thicker skin, square jaw surgery typically does not result in sagging.

However, if you already have mild skin sagging before surgery or have poor skin elasticity, it is recommended to undergo square jaw surgery in combination with a facelift to help prevent postoperative sagging.

Candidates for Square Jaw Surgery

If the overall square jaw is large and developed
If you have wide jaw angle from the frontal view
If you have severe jaw asymmetry
If the curve of the jawline is severe
If you want to have a smaller/slimmer face

FAQ

Why is blood drainage maintained after the surgery?

Blood can leak from places such as the nostrils during cheek bone surgery. However, there is no such place in jaw angle surgery for the blood to leak out.

When can I depart Korea after surgery?

It is recommended that you stay in Korea for 13 days. But depending on your situation, you may be able to leave the country after 5 to 7 days; in this case, you’ll have to get your stitches removed in your home country.

Is it safe to proceed with other surgeries together?

Since the chief anesthesiologist is present in the hospital to closely monitor the entire procedure, it is safe to undergo multiple surgeries at once.

When will I see my result?

You should wait at least 6 months to a year to see the full results, but you can already see improved results 2 to 3 weeks after surgery.

Are there any long-term side effects from this surgery?

All surgeries carry the risk of complications. In the case of a jaw angle surgery, the location of the nerve line is crucial. That is why it is critical to have surgery performed by a skilled surgeon.

What are the things to consider once I get home?

We advise to avoid eating chewy food, having extreme sports for 2months.

Can I have surgery while wearing braces?

Wearing braces during surgery is not a problem. However, because opening the mouth wide after surgery is uncomfortable, you shouldn’t receive orthodontic treatment for 2 to 3 months.

Can I eat hard foods after surgery?

After surgery, eat soft foods like porridge for about a week and avoid very hard foods for 1 to 2 months.

Is there any visible scarring?

There are no visible scars because the incision is inside the mouth.

Is the surgery process painful?

It's more uncomfortable than painful. Painkillers are prescribed because each person experiences pain differently.

Will there be any problem boardinga plane?

There will be no problem boarding a plane 5-7days after surgery.

What are the side effects of facial contouring surgery?

All surgeries carry the risk of swelling, scarring, infection, and bleeding. This may differ depending on the patient's physical condition and post-surgery care.However, if the surgery is decided after extensive consultation with an experienced specialist, the risk of side effects is greatly reduced.
