Jaw angle hypertrophy is due to bone growth in the jaw angle area of the lower jaw bone or accompanied by different degrees of bite muscle hypertrophy, resulting in a wide lower face, showing the characteristics of a “square face”. Through the jaw angle osteotomy can change the “square face” to the “goose egg face” or “melon face” that the Chinese people like. The surgery is safe because the facial artery and facial nerve are protected by special methods. The minimally invasive treatment for the lower part of the face is bite muscle toxin injection. The high zygomatic arch increases the width of the middle third of the face, and because of the aesthetic bias against high zygomatic bones in the Eastern culture, many patients request surgery to reduce them. The width of the midface can be changed through intra-oral approach or osteotomy, which does not leave a scar after surgery. The alternative treatment to zygomatic osteotomy and reduction is autologous fat transplantation in the temporal and subzygomatic areas, which can create a natural and smooth midface contour. The ideal chin protrusion should conform to Ricketts aesthetic plane, i.e. the lateral lower lip edge is on the line from the tip of the nose to the chin, while the front edge of the upper lip is slightly retracted on the line. For small chins, chin augmentation or chin osteotomy can be used to improve the prominence and length of the chin. Minimally invasive treatments for short or receding chins are autologous fat transplantation or hyaluronic acid injections.
