A, round square

Characteristics of a round face: it is a short face (that is, a short chin), with a wide face but gentle lines and no prominent edges and corners. This face makes the facial features inconspicuous, that is, the feeling of fuzzy facial features.

Operation method: bone grinding operation. This kind of operation does not need to remove any bone, but only needs to use professional grinding tools to thin the outer layer of mandibular angle bone, thus reducing the width. The thickness that can be ground off is limited, only 5 to 6 mm at most. This kind of facial cosmetic surgery is simple in technique, light in injury and quick in recovery. This kind of face improvement effect is effective, which is only suitable for faces with less obvious edges and corners, and only needs a little adjustment.

Second, the square.

Features of square face: short face, not wide but strong lines, strong sense of bones, short chin and slightly raised tip.

Surgical method: mandibular angle splitting operation. This operation is to remove the external bone of the mandibular angle without removing the whole mandibular angle.

People with this face shape will not have a wide face, and often only the back part of the chin is more prominent. By cutting off part of the mandibular angle, the width is reduced and the original facial curvature is preserved. Face modification for this face is dangerous, and the bleeding needs to be controlled. People with coagulation dysfunction, anemia and facial hemangioma are not suitable for this method.

Third, the corner square.

Facial features: It is a typical Chinese face with wide and powerful lines, and the mandibular angle even protrudes backward, giving people the impression that the masticatory muscles are particularly developed.

Surgical method: Mandibular angle resection. This operation is to completely remove the mandibular angle, but it should be noted that the arc of the incision must match the chin.

Fang's face is obviously changed, and the mandibular arc can be reshaped; Without the support of bones, the masticatory muscles will slowly shrink, and the problem of masticatory muscle hypertrophy will be solved. Face modification for this kind of face is technically difficult and dangerous. To cut the marrow cavity, it is necessary to control bleeding and screen the operators.
