Many people think the key factors that determine a person’s appearance are the eyes, nose, and mouth. Of course, appearance can change depending on the shape of the eyes, nose, and mouth, but what contains them is the “face shape,” meaning the facial contour line is extremely important. Because it is a structural part, if the bone framework or contour shape is unbalanced or distorted, it needs to be improved through surgery. Looking at reviews of contour surgeries such as square jaw, cheekbone, and genioplasty at ATOP Plastic Surgery, you can see that simply improving the facial line can further enhance the strengths of the eyes, nose, and mouth. In particular, if you are concerned about the length or shape of the chin bone, which is located at the bottom of the face shape, you can improve it through surgery tailored to that design.
Improving an ideal face shape with contour surgery
Facial contour surgery is made up of the so-called three procedures: cheekbone surgery, square jaw surgery, and genioplasty. A slim, soft face shape with natural curved lines is considered the most ideal. To achieve this shape, bone is removed, but once bone has been cut, it cannot reattach or regenerate, so the initial surgery must be approached very carefully. If too much is removed, the face shape may instead look more distorted.
Everyone’s facial contour is different, because the shape of the bones, as well as the amount of fat and muscle, are all contributing factors. That is why contour surgery must be designed to suit each individual. Rather than removing or moving bone unnecessarily, only the amount needed should be adjusted. Genioplasty in particular requires even more caution because the area is smaller than the square jaw or cheekbones.

Chin advancement surgery, bringing the jawline forward
If the chin bone is excessively set back, the proportions of the face may look awkward, and it can also affect the overall impression. In such cases, it needs to be brought forward to create harmonious proportions and balance. That is exactly what “chin advancement surgery” is for. By moving the bone that sits somewhat farther back to the front, it is possible to improve the chin into a balanced, soft shape. Adjusting it to the proper position and length allows for a natural improvement.

Chin setback surgery, reducing the length and width of a long chin
Unlike chin advancement surgery, “chin setback surgery” is a procedure that pushes protruding bone backward, in other words, sets it back. If the chin bone protrudes farther than the lips or the tip of the nose, or if it is long, the overall length of the face may look longer and the impression may feel stronger. Since the bone is already positioned toward the front, it is difficult to compensate for it with other procedures, so it must be moved backward.
This surgery improves the chin by horizontally osteotomizing the jawbone to reduce unnecessary length and then narrowing the width as well. It can create a softer, more refined shape, and if the bone is positioned 3–4 mm farther back when viewed from the side, the result can look natural and balanced.

T-osteotomy, improving a broad chin width and length
Genioplasty can improve both the front and side views. Among these, if the front chin is wide, the impression may look coarse, and the chin itself may appear broad horizontally. Some people with a developed square jaw also have this shape, and in such cases it can be improved by combining the procedure with a T-osteotomy.
T-osteotomy is a representative genioplasty method in which the chin is cut into a T shape when viewed from the front, the unnecessary bone in the center is removed, and then the bones on both sides are brought toward the center and fixed in place. If the chin is wide and long horizontally, T-osteotomy can create a sharp, slim line. It is a method that can improve the overall balance of the face while shaping it into a pointed V-line.

A blunt chin, improving dimensionality with an implant
If the chin is short and flat, like a weak chin, the lack of volume can also reduce dimensionality, making the overall impression look vague. In such cases, rather than bone-moving procedures such as advancement surgery, the missing area can be supplemented by directly inserting an implant.
If the tip of the chin is round and blunt, the length itself may also be short. When an implant is inserted during genioplasty, the effect can be expected relatively simply and quickly. This is completed by making an incision inside the mouth, inserting a properly designed implant, and suturing the area closed, allowing the chin line to become more three-dimensional. Because the implant design varies depending on each person’s chin shape and form, the procedure should be carried out after sufficient consultation.

Customized surgery based on chin type
Everyone’s face shape and jawline are different, and the chin also comes in many types. There are various types such as weak chin, wide chin, long chin, and asymmetry, and these may also appear in combination. Therefore, when performing genioplasty, it must be done in a way that suits one’s own chin shape and form.
In particular, because sensitive nerves are intricately distributed around the chin area, care must be taken to prevent nerve damage. A safe procedure requires anatomical understanding, skilled technique, and extensive surgical experience.

As with all contour surgeries, more bone removal is not always better in chin surgery either. I hope you can have enough consultation and make your decision so that careful adjustment of only what is needed can create a beautiful, balanced contour and become a review of ATOP Plastic Surgery that you can be satisfied with.
