Hello. This is Woori Plastic Surgery.
Today, we’d like to talk about square jaw reduction surgery, which many people concerned about a broad facial shape often look into. We’ll take a look at why the square jaw appears more prominent and how the surgery is performed.
Why the Square Jaw Appears Prominent

There are two major reasons why the jaw can appear wide. The first is when the jawbone itself develops broadly and angularly, like a square. The second is when the masseter muscle (the jaw muscle) becomes overly enlarged, making the face look wider. Many people have both factors at the same time, so an individual diagnosis is important. In practice, surgical results are usually most noticeable in cases with a bulky skeletal structure. In particular, if the jawbone spreads outward toward the back, the change to a slimmer appearance becomes much more distinct after contouring.
Square Jaw Reduction Surgery Method

Square jaw reduction surgery is a method that directly reduces the broad lower-face bone structure to narrow facial width. By removing the overly prominent bony areas and smoothing them out, the face looks smaller from the front, and the jawline becomes much softer from the side as well. The larger the bone, the greater the degree of change, and when muscle development is also significant, combining the procedure with muscle reduction can create a more natural V-line effect. When both bone and muscle are refined together, the advantage is that the facial impression changes significantly while the overall facial proportions become more balanced.
The Difference Between Muscle Reduction Surgery and Botox

Muscle reduction surgery and square jaw Botox have similar principles, but their duration is clearly different. Botox blocks nerve signals so that the muscle gradually atrophies on its own, but over time it returns to its original size. In contrast, muscle reduction surgery helps the muscle shrink permanently by using heat to destroy a specific nerve pathway. The key difference is whether the change is temporary and maintained by medication or whether it is a permanent structural change.
Because square jaw reduction surgery requires different approaches depending on the shape of the bone structure and the degree of muscle development, accurately analyzing each person’s facial structure is most important. Please make a good choice after 충분히 discussing it with a contouring specialist.
