The square face is mainly manifested by a wide jaw angle and parotid bite area, a flat jaw plane, a disproportion between the middle and lower face width, and a disproportion between the full height and face width, and a specific square face. Oriental people are beautiful with oval or goose egg shaped face, and the important feature of beauty is overall facial coordination and harmony. For square faces, surgery can be used to change the face shape. According to the different facial contour characteristics of the patient, when reshaping the square face, the overall beauty is the starting point, and through the harmonious matching of the components, the overall coordinated facial contour can be obtained through a comprehensive selection of surgical methods. First of all, we should analyze the cause and degree of deformity of the patient, the parts to be amputated or moved, and initially determine the surgical method, then discuss fully with the patient, and jointly develop a surgical plan according to his subjective requirements combined with the objective reality of surgery. Usually, the patient’s facial contour can be reshaped as a whole by combining chin shaping, partial removal of cheek fat pad, zygomatic osteotomy and other auxiliary cosmetic surgeries, and most of them can achieve satisfactory postoperative results.
