What is squared jaw reduction?

Squared jaw reduction makes a soft and slender V-line balanced with the face.

In general, the bony structure of face is different individually, so it is necessary to perform squared jaw reduction customized to each patient's condition. If the both sides of chin is protruding, making a squared jaw, women may seem strong and stubborn, and may look unsophiscated.

If you correct squared jaw, your impression will become more sophiscated and you will even get an effect to make your neck look longer.

Professional medical team with rich experience and many-years’ know-how in surgery directly performs a surgery!
  • It will reduce the thickness of bones, not just cut the squared jaw!
    As Ruby's squared jaw reduction even reduces the thickness of bones unlike existing squared jaw reduction, you can get the maximum effect to make a face even smaller by reducing the width.
  • It will make a slimmer face by performing surgery on both squared jaw and the frontal chin!
    It will enhance the effect from the front by cutting the end of chin as well as squared jaw. It will make a beautiful V-line from any angles by reducing the width of jaw and drawing the end of chin through T-cutting technique depending on the situation.
  • Surgery is performed safely along the nerve line.
    A method to cut the jawbone straightly like existing squared jaw reduction may cause tremendous results depending on doctor's skills. As facial contouring surgery is very difficult surgery to cut the jaw where nerves are located, you'd better get the surgery from professional medical team with many-years' experience in order to get a successful surgery result.

Surgical method

T-cutting technique

T-cutting technique is a surgery method to cut the jawbone in a T shape, to remove protruding part in the middle, to draw the bone at the end of jaw, and to make the chin line smooth. As T-cutting technique can adjust the width and length of the end of jaw as you want, it can adjust the ratio of chin, and make it smooth even when the width of jaw is too high or location of the chin does not match to each other.

V-cutting technique

V-cutting technique is a surgery method to cut the jawbone in a reversed V shape, to remove protruding part in the middle, to draw the bone at the end of jaw, and to make the chin line smooth. As it can adjust the movement forward/backward as well as the width and length of jaw, it can adjust the ratio of chin, and make it smooth even when the width or length of jaw is too high or location of the chin does not match to each other. Unlike other square jaw surgeries, V-cutting technique can give you an effect from the front and from the side.

Reversed V-cutting technique

Reversed V-cutting technique is a surgery method when the length of jaw is high. It cuts the end of jaw in a reversed V shape, and adjusts the length of jaw, making a slimmer V-line.

Cortex bone-cutting technique

Our face bones are composed of 3-layered structure including outer cortex bones, sponge bones, and inner cortex bones. Cortex bone-cutting technique is a surgery to peel out the outer layer. As cortex bones are located on an area nearest to skin, it may cause the side effect of creating rough skin or squares when simply peeling out, so it requires know-how of experienced medical team.

Lower jaw-cutting technique

Lower jaw is a part where the lower jawbone is curved under the ear. The surgery effect will be maximized when a patient's jaw is large. As this technique directly cuts the protruding bone, it makes a gentle and soft line, and makes a small and slim face from the front as it shortens the distance between a nose and the lower jaw. The most important thing in the lower jaw-cutting technique is to decide how much the jaw is cut in a thorough plan, and to cut the area exactly.
