Many oriental women want to have a soft oval or rounded face, but horizontal protruding cheekbones often give the face a diamond or square shape. The zygomatic bone, as the main support structure in the middle of the face, has an important influence on the facial contour and appearance of a person. Western races have a long, flat craniofacial shape, and high cheekbones can add layers to the face. In contrast, Eastern races have relatively wide cheeks and low frontal orbits, and high protruding cheekbones can appear disproportionate and lacking in beauty, especially in the south of China where there are more people with high cheekbone face shapes. With the development of various aspects, zygomatic bone and zygomatic arch reduction, which is entirely for cosmetic purposes, is gradually carried out in China. The zygomatic bone can be divided into two parts: the “zygomatic body” and the “zygomatic arch”, which determine two important visual angles. When the face is viewed from a 45-degree angle, the curvature of the zygomatic body determines the aesthetic appearance of the face. If the zygomatic body is too developed, the curvature of the protruding body is too large, destroying the beauty and creating an impression of a strong personality that is not soft enough. The zygomatic arch is the part of the zygomatic body that extends backward (toward the external ear canal) and connects to the temporal bone, and from a frontal view, the widest part of the face is at the zygomatic arch. Cheek hollows, temporal (temple) hollows, and excessive thinness can make the cheekbones appear prominent. Instead of cheekbone surgery, the appearance of protruding cheekbones can be improved by addressing temporal and cheek hollows. There are two main concepts of zygoma reduction: one is simply chiseling to reduce the outer contour of the cheekbone, and the other is reduction of the zygomatic arch. Both procedures use an intraoral incision and special instruments to chisel away and thin the part of the cheekbone that is designed to be removed before surgery, thereby reducing the external contour of the face and improving its shape. In contrast, zygomatic arch reduction requires the amputation of a specific sized bone block to depress the zygomatic arch, and then the reattachment and reshaping of the zygomatic arch using special materials such as titanium nails, so that the entire facial contour and shape can be changed to the greatest extent possible. In addition to zygomatic bone reduction, for a small number of patients with localized depression in the middle of the face due to congenital or acquired diseases and other causes of zygomatic bone dysplasia or defects, or bilateral zygomatic asymmetry, treatment can be performed by filling the zygomatic area with autologous bone grafts or prosthetic materials to improve the appearance. In the case of zygomatic arch reduction, it is best to perform it under general anesthesia.
