Considerations and Prevention Methods for Square Jaw Reduction Surgery

Square jaw surgery is a type of plastic surgery performed to improve cases where the lower jaw has developed into a wide or angular shape,

creating a more slender and softer facial contour.

It is mainly carried out by refining the shape of the chin tip and jawline, or by removing or reducing the angular part of the lower jaw,

and is often performed when the goal is to soften a strong jawline and make the face look more feminine and harmonious.

A commonly concerned issue after square jaw reduction surgery is the jaw opening unnaturally and a new angle forming below the removed jawbone area. Today, we will look at how the surgery should be performed to help prevent this.

Resection with a natural curve design

A natural curve design is a surgical method used when removing or reducing bone in square jaw surgery,

where the goal is not to shave off a straight angle, but to adjust the jawline so it draws a smooth curve.

Through this, the face can become naturally more slender, and a softer jawline can be created especially in profile.

The middle portion of the human lower jawbone has a slightly rounded outward curve.

When square jaw surgery is performed with a smooth resection that takes this "rounded curved line" into account,

the jawline after surgery can appear natural and balanced.

How to prevent damage to the jawbone nerve canal

When performing long-curve square jaw surgery that removes bone from the angle under the ear to the front part of the jawbone body,

if the bone is resected with an inward concave or straight shape,

part of the nerve line may become too close to the resection line.

On the other hand, if the jawbone is refined in a slightly rounded natural curve shape on the outer side,

it can be resected while maintaining a safe distance from the nerves,

allowing for a soft and natural result after surgery.

This method also helps reduce the risk of nerve damage.

The relationship between long-curve square jaw surgery and prevention of secondary angles

In general square jaw resection surgery, if the angular part of the jawbone is cut in a straight line or removed excessively,

the bone left below it may form a new angle.

On the other hand, long-curve square jaw surgery does not simply remove the angle of the lower jaw,

but is designed so that the jawbone is resected in a smooth curve and connected naturally.

This method makes the facial contour appear natural and smooth after surgery,

and can help prevent the removed bone from abruptly bending and creating a new angle.

Cortical bone resection to maximize the frontal effect

Cortical bone resection is a surgical method that refines the surface of the bone (cortical bone, meaning the outer part of the bone) to improve facial contour.

Rather than removing the deep layer of the bone, it is characterized by adjusting only the outer part of the bone to create a smooth and natural contour.

Rather than removing the deep layer of the bone, it is characterized by adjusting only the outer part of the bone to create a smooth and natural contour.

This surgery thins and reduces bone thickness by carefully shaving only the outer surface (cortical bone),

and it can have the effect of making the face look more slender from the front.

Because only the cortical bone is removed, it does not damage the deep bone tissue,

which has the advantage of minimizing the risk of nerve damage or functional side effects.

Square jaw surgery plays an important role in naturally improving the jaw contour,

and depending on the surgical method, safe and natural results can be achieved.

When the jawline is refined softly and smoothly through a natural curve design,

the facial contour after surgery becomes more slender and balanced.

Also, using methods such as cortical bone resection can adjust the bone surface to create a more natural and refined contour,

and help prevent nerve damage or functional side effects.

These procedures can be safely performed through careful surgery by a specialist,

and may provide patients with more satisfying results.

※ Depending on the individual, side effects such as inflammation, bleeding, and nerve damage may occur, so sufficient consultation with medical staff before surgery is necessary. This is an example image to help with understanding.
