This procedure is a small operation for reducing the prominent cheekbones; its range of bone reduction is limited to the section from the anterior zygomatic body (below the eye sockets) to the parts near the junction of the lateral zygomatic body and zygomatic arch. The main goal of this procedure is not reducing the face width but softening the facial contour in the 45° side view or improving the condition of the asymmetric cheeks. Usually, this procedure is not performed only for fixing a wide face, but as a procedure for assisting in zygomatic bone cutting or a fine adjustment for revision surgery. The process of this surgery is relative simple; surgeons only need to make a 1.5–2cm incision in the intraoral upper gum, detach the skin from the bone, and then, directly grind off the protruding part of the zygomatic bone. Because the whole procedure needs no bone cutting, bone fixation, and additional incision in front of the ears, postoperative recovery is very fast. Because the range of this procedure is limited to the section from the zygomatic body to the lateral one-third of the zygomatic arch, it only regionally improves the condition of cheek protrusion in the front and 45° side views. This surgery will not achieve any reduction in patients with a truly wide face.
