The jaw is best described as the articulated framework bearing the teeth at the entrance to the mouth and is, essentially, compromised of two main bones, their overlying muscles, and a covering of skin and fat.
The upper jaw bone is known as the maxilla, while the lower jaw bone is called the mandible. The sizes of the mandible and its main muscle, the masseter, are the primary anatomic factors determining the width and shape of the lower face, often called the "jawline."
Some Asian women prefer a more slender jaw profile to a stronger square or flared contour that might feel out of proportion to other more delicate facial features. Slimming does soften the facial contour and can make the neck appear slightly longer. However, a square jaw is often assoicated with high cheekbones and more forward thrust on the chin, and so reducing only the square angle may imbalance the face.
Some women feel a square jawline makes them appear less feminine, although this argument is flawed. There are countless beautiful women with extremely square jaws and many handsome men with highly angled jaws.
On the other hand, more than a few women see a prominent jaw as a sign of "superior" beauty. Those with square jaws tend to show tighter skin with less tendency to develop a double chin or as much facial sag with aging.
Jawline reduction can be undertaken using either permanent surgical or temporary non-surgical methods. It is often performed in conjunction with chin augmentation if the chin is underdeveloped.
Surgical reduction of the mandibular angle is particularly effective in changing a square-shaped face into one with a more oval contour.
"Double jaw surgery," the common name for a diverse group of operations that are becoming increasingly popular in South Korea, alters the anatomic relationships of all components of the mid and lower face, including the mouth, lips, teeth, chin, cheek, and jaws.
3D CT scanners are now routinely used to image deep facial structures during the planning stage. More precise lasers can be used instead of electric saws during cutting and/or removal of bone.
