If there are no problems after jaw plastic surgery, there will be no downward displacement. The effects of surgery can last forever, and the results are still very good. The bandage can be removed and discharged from the hospital 5 days after the operation. At this time, the swelling of the soft tissue in the surgical area has not completely subsided. The effect of the operation is only 80-90% at this time. The best effect of the operation will not be apparent until half a year later.
