Mandibular angle plastic surgery is to choose a suitable surgical plan according to everyone's detailed situation, stop cutting off the hypertrophic mandibular margin and part of the masseter muscle, and perform the operation in the mouth without leaving any scars after operation. In addition, after the operation is completed, the facial edema is added with elastic bandage, so that the edema disappears within 1-2 weeks, and ice compress can be used appropriately to reduce swelling faster, which can effectively achieve the expected therapeutic effect.

There are two methods for plastic repair of mandibular angle hypertrophy:

1. Hypertrophic mandibular angle plasty; The ascending ramus of mandibular margin is too long, resulting in an angle less than 120, which is seriously at right angles. By cutting off too many "angles", the angle can be returned to 120, and the curve is smooth. The operation time is short.

2. Hypertrophic mandibular angle plastic surgery; Mainly aimed at the hypertrophic mandible, the ascending ramus of mandibular angle (the outer plate of bone) is ground off, which makes the mandible with wide front field of vision sharp and thin, and has the effect of thin face and smooth face.
