Doctor Lee Jin-soo's plastic surgery essay 31- Reverse Estimating Amount of Lesson (REAL)

Facial contouring surgery is commonly referred to as surgery to change facial shape by operating on facial bones.

There are two main ways to operate on a facial bone. One is to cut or trim bones to reduce them. Typically, square jaw surgery is a bone reduction surgery.

Another is how you cut the bone, and then move the bone. Cheekbones and jaw end surgeries use the way they move.

There is a point that must be considered in the area where the jaw bone is reduced and the face shape is changed.

The degree of reaction to bone changes is different for each jaw region.

For example, even if you cut the bone straight, the jawline that you see on the outside is unfortunately not straight. This is because each part of the jawline reacts to the reduced jawbone. So the parts that respond well will go in, and the parts that respond less will look relatively bulky. And the fatter the jawline, the less elastic the skin is

Specifically, the jaw tip is less responsive due to muscles, and the middle of the jaw line corresponding to the body is less responsive due to fat and sagging skin. On the other hand, each part has a good response and the middle of the jaw and body is also a good response.

If you cut a lot of jawlines in a straight line, it's easy for the jaw tip and the body part to go into the embedded shape, and the body part to become bulky. It's similar to an old man's sagging jawline.

So when you plan a bone surgery, if you plan how much you want to cut just by looking at the shape of the bone, the actual face will look different from the plan.

My idea of REMA is a new jaw bone surgery plan that addresses this problem.

First of all, we look closely at the actual facial condition as well as the skeletal state of the X-ray. In particular, we understand the situation of the soft tissue, the elasticity of the skin, the amount of fat on the jawline, and the current sagging of the skin as accurately as possible.

Then you determine the amount of change in the actual face.

Finally, we determine the bone removal area and the amount of deletions that can bring about the actual amount of change in the face. Considering the reaction to the skin, the reduction of bone is calculated upside down, so it is called the reverse estimation method.

The big principle here is to reduce the number of bones where the skin reacts well to bone changes, and the number of bones where the skin reacts less. Specifically, between the tip of the jaw and the body, which have a good skin reaction, the bones of each part are reduced less, and the bones of the body, which is less responsive to the skin, are reduced.

In conclusion, if you cut straight into a straight line, looking at a picture of a bone, you should evaluate the condition of the soft tissue and apply the appropriate amount of surgery to each part of the jawline to create a smoother and more attractive jawline.
