The reduction of a square jaw to create a V-shape can be achieved using surgical and non-surgical methods. Surgical jaw reduction involves an incision inside the mouth to remove the outer layer of the enlarged mandible or jawbone, narrowing the contours of the jaw. However, this can involve complications like the loss of sensation on the lower lips and teeth.
On the other hand, the non-surgical approach to square jaw reduction involves a simpler process which forgoes incisions, bleeding, and downtime. It involves injecting a measured solution that relaxes the jaw muscles. It targets the masseter muscle, in particular, reducing its size over a period of time. By doing so, this gradually creates an inverted triangular profile to the lower half of the face.
