A square jaw is a jaw whose bones under the ear are angled like a square; the angular bone can make one's features more pronounced or make one’s face look larger than it actually is. In this case, a long-curved square jaw surgery is a good method of ablating the angular jaw bone.

Unlike the conventional surgery that removes only the angle of the bone, FACE also reduces the thickness of the bone using cortical bone resection. As the jaw muscles and bones are reduced together, the face gets smaller, and facial contour that makes the face look slim even from the front is achieved.

  Cortical bone resection

  In the case of thick jaw bone, the outermost cortex is removed from the triple-layered bone structure to reduce the thickness of the jaw bone so as to narrow the width of the face and make it slimmer.

  Angle resection

  It is effective for overgrown jaw angle. The operation cuts the excessively developed jaw angle under the ear to realize a slim, smooth line overall.
