 What's the difference between  facial contour surgery and two-jaw surgery effective for facial asymmetry correction?

Elastic skin and a smooth face line play an important role in determining a favorable first impression.  When we think of a beautiful appearance, we often imagine a face with prominent features, but what's equally important is the balance of the face, which should be symmetrical on both sides. However, everyone's face has a slight asymmetry between the left and right sides. If the imbalance between the left and right is noticeably visible to the naked eye, it's not aesthetically pleasing, can cause inaccurate pronunciation, or jaw joint disorders, and can negatively affect the formation of your image or mood, becoming a complex.

Most facial asymmetry occurs due to various reasons such as asymmetry of the skeleton during growth, changes in contour after trauma or surgery, or when the muscle strength becomes imbalanced. Firstly, skeletal asymmetry that occurs during the growth process can become asymmetric due to genetic influences, differences in the rate of development between body parts, and imbalanced muscle use.

Especially during adolescence when the skeleton is developing, contour asymmetry can become more pronounced, and asymmetry can occur due to incorrect posture or eating habits that lead to more frequent use of one side of the face, or differences in muscle size or length on one side of the face.

Also, changes in the contour after trauma or surgery can also be one of the causes of facial asymmetry. For example, if you try to correct asymmetry through surgery that cuts and moves one of the two jaws, asymmetry can appear due to side effects after surgery.

There are various ways to resolve facial asymmetry, but it's necessary to correct the asymmetry with a method suitable for you. Most people often confuse facial contour surgery and two-jaw surgery, which are most effective for correcting facial asymmetry. So in this post, I'll explain in detail the difference between facial contour surgery and two-jaw surgery, which are effective in correcting facial asymmetry.

What is the difference between facial contour surgery and two-jaw surgery?

For skin elasticity decrease due to aging, or excessive fat development due to incorrect lifestyle habits that worsen asymmetry, non-surgical treatments such as lifting procedures are possible. However, if asymmetry occurs due to muscle and skeletal imbalance from birth, fundamental bone surgery such as two-jaw or facial contour surgery is needed.

What is facial contour surgery?

Generally, facial contour surgery can be described as a surgery that focuses on changing the surface of the bones that make up the face, such as the cheekbones, square jaw, and front jaw. In other words, it is a surgical method that gives a slight change in position and volume by trimming or cutting a part of the bone that has excessively developed and breaks the balance of asymmetry or contour.

In cases where there is a difference in the height of the jaw or the width of both sides of the jaw, or where only one side has developed significantly, problems such as long jaw, spade jaw, jawlessness, or short jaw can be corrected with facial contour surgery by just shaving off the problematic bone part.

This facial contour surgery can create a smooth face line by trimming the contour line when the cheekbone is protruding, the square jaw is prominent, and the side line of the front jaw looks asymmetric due to bulging.

What is Two-Jaw Surgery?

On the other hand, Two-Jaw Surgery is a surgery that corrects the occlusion of the maxilla (upper jaw) and mandible (lower jaw) to create an ideal face.

In cases where the protrusion is severe or the occlusion itself is significantly twisted, causing the bones to be twisted and the asymmetry is severe, the two-jaw surgery can be said to be a procedure that makes a three-dimensional positional movement in the center of the face, such as left and right, front and back. Since it is a method of correction for those who have difficulty eating or speaking because their mouths are excessively protruded or their occlusion does not match, it can be said to be closer to a therapeutic purpose. Also, it corrects the position of the jaw that is out of the normal range, such as spade jaw, protrusion, facial asymmetry, and not only improves function but also improves appearance.

Both facial contour surgery and two-jaw surgery methods can correct facial asymmetry that directly deals with facial bones, but just because there is asymmetry, it does not mean that such surgery must be decided. It is important to choose the right surgical method for yourself, as there may be differences in the area of bone osteotomy, recovery period, whether or not orthodontic treatment is necessary, and the effect of improvement, as mentioned earlier.

In addition, due to the differences in the causes and degrees of asymmetry, and the tilt or rotation of the axis in each individual, it is necessary to have sufficient consultation with medical staff who have abundant anatomical knowledge of bones, clinical experience, and know-how to understand more detailed problems. Also, it can be said that establishing a suitable surgical plan after accurate diagnosis through 3D-CT imaging that can identify specific internal problems is a way to satisfactorily correct facial asymmetry.

Therefore, if you are stressed by facial asymmetry, I recommend that you receive careful consultation and accurate diagnosis from medical professionals who can apply solutions based on an accurate understanding of the bone condition.
