Serious asymmetry between left and right face can be corrected by liposuction, bone grinding and osteotomy, Botox injection and so on. 1. Liposuction: If the severe asymmetry of left and right face is caused by fat factor, then it can be corrected by liposuction. 2. Osteotomy: If the problem is caused by the bones of the left and right faces, it can be corrected by surgical osteotomy or jawbone grinding. 3. Botulinum toxin injection: If there is no obvious bone abnormality, we can consider that it is caused by the difference between the two sides of muscle hypertrophy. If the difference between the two sides is obvious, Botox injection is usually recommended to correct it. If there is a serious asymmetry between the left and right side of the face, it is recommended to go to the hospital in time for regular treatment.
