What is square jaw surgery?

The surgery reduces the size of the developed lower jaw.

The square jaw refers to the chin with large and angular square jaw due to the development of the mandibula (lower jaw) and the surgery reduces the size of this chin.

The surgery incises the square jaw to the oral angle to feel slim not only from the front but also from the sides and performs muscle reduction and fat removal to provide a more defined face with definite volume reduction.

Why the square jaw surgery is called baby-face surgery

The slim face in the 20s tends to become angular and wide from the 30s when aging begins.

The wide jaw gives an aging appearance and it is because a long time of chewing wears out the teeth and strengthens the jaw muscles.

The strengthened jaw muscle naturally makes the supporting bones thick. In this case, the surgery restores the previously slim jaw line through the surgery and improves the image to a young face.

Special features of VIEW’s V-line surgery

Good looks from the front

Reduce the width of the front chin and volume of the square jaw to form a slim and slender front appearance.

Improved looks from the sides

Reduce the width of the square jaw and form a side line smoothly connected to the front chin.

Less swelling and more elasticity

Special care, the last stage of the surgery helps the quick removal of swelling and completes an elastic face.

Bone scalpel enhancing the accuracy
The bone scalpel is an ultrasonic device which cuts the bones by responding only to the bone tissues.

It has less vibration within 0.5mm enabling a very precise surgery, protects nearby blood vessels and nerves by responding only to bones, causes less tissue damages and bleeding and provides quick recovery.

1Long curve resection
Surgery method

Perform gradually sloping resection of the lower chin from the area below the ear to the oral angle in a long curve.
The square jaw from the front turns into a smooth line and makes a smooth chin line from the sides.
The surgery can correct even severely asymmetric jaws.

Classification Long curve resection Mandibular angle resection
Surgical site Cut in a gentle slope from the angular part below the ear to the front Cut only the angular part below the ear only
Incision No visible scars due to incision inside the oral cavity Scars left due to the incision behind the ear
Effect Slim looks from the front and sides Slim looks from the sides
Chin line Smooth and slender line with no additional angles No need to worry about additional angles

2Cortical bone resection
What is the cortical bone?

The bones in the body consists of 3 layers: outer cortical bone, cancellous bone and inner cortical bone. The cortical bone we often refer to is the outer cortical bone with the strong bone tissue in the outer part and this surgery carefully cuts only one layer of the bone to reduce the facial volume.

Surgery method

The cortical bone resection peels off some of the bone surface like peeling off a banana to make a slimming effect.
It is only 2mm of the cortical bone to be peeled off for most people but it has a significant difference from the front side. Additionally, the surgery removes the developed muscles and fat for better results.

3Muscle reduction surgery
Surgery method

This is a method using a small medical needle to transmit high frequency waves to burn and reduce part of the muscles.
At this point, the number of muscle cells rather than its size is reduced and the surgery is semi-permanent because the degenerated muscle cells are never reproduced. The surgery reduces the thick muscles for especially developed masseter muscles from chewing to give a slimmer look.

4Removal of deep facial fat
Removal of deep facial fat

There is a long lump of fat from the temple beside the eyes to the side of the lips on the side of the face. It is called “isthmic fat” in medical terms and is also referred to as “deep facial fat” because the excessive amount of fat around the cheek makes the cheek look protruded. It is often seen during childhood but some remains even in adulthood.

Surgery method

Remove fat through the oral cavity. Excessive fat removal may damage nearby nerve tissues or salivary gland and make the cheek look sunken. Therefore, the exact position of the fat must be identified first and then 4 – 5cc of the fat must be removed through experienced skills.

23D CT upgrading the operational precision and stability

The 3D CT irradiates the X-ray into the human body and reconstructs the image with the computer to display the internal status with multidimensional images.

Unlike the existing X-ray image, the technique shows more than 3,000 times higher precision and thoroughly analyzes the size, location, depth, length and width of the facial bone to provide a customized operation plan with the operation method and range.

Furthermore, safe surgery is performed by precisely understanding the location of neural glands to prevent nerve damages.

Please be careful because common complications like bleeding, infection and inflammation after the surgery varies by patient.
