The recovery time of mandibular angle plastic surgery is also different due to personal recovery and physical influence. It is worth noting that there will be swelling in different degrees during the recovery period of this operation, but it will gradually subside in 3-7 days. The suture can be removed in about one week after mandibular angle plastic surgery, but it takes about 1 month to completely reduce swelling. The masseter muscle will achieve the best effect in about 6 months because of the change of attachment position and muscle tension in 3-6 months.
