The facial prominence is mainly composed of the nose, cheekbones and chin prominence, which are important anatomical structures that highlight the features and three-dimensionality of the human face. The coordination of facial protrusions is an important indicator of facial beauty: the nasal protrusion is located in the midline of the face; the zygomatic protrusions are located in the lateral part of the face; the chin protrusion is located in the lower third of the face. The shape and prominence of the cheekbones have a great impact on the appearance. Oriental people have soft facial contours and rounded lines, and their nasal and chin protrusions are more moderate, while excessively high cheekbones destroy the harmony of facial protrusions and break the unity and coordination of facial beauty. In addition, some superstitious ideas also make people dislike the high zygomatic protrusion, especially young women. The oriental aesthetic standard is that the most beautiful face is round, and the face of zygomatic protrusion is mostly round, and the face of those with jaw angle hypertrophy is square, and its facial profile is characterized by high zygomatic protrusion, wide face in the middle 1/3, and concave face 1/3. Zygoma correction surgery can reduce the height of the cheekbone and achieve amiability, coordination and unity of the facial protrusions. In China, the oval face shape, commonly known as “melon face”, is considered to be the most ideal. Especially for women is more important, because only this face shape, whether from the front or from the side, are proportional coordination. But the jaw angle hypertrophy, so that the facial length and width ratio is out of proportion, square face, seriously affect the appearance of beauty. By removing the overly prominent part of the jaw angle and restoring the normal jaw angle shape, the jaw angle hypertrophy correction surgery can change the face shape into a beautiful oval or melon face.
