Chin plastic operation, as one of the classic projects of mandibular angle plastic surgery, can obviously improve the aesthetic feeling of the face. In general, the number of patients seeking surgery has increased in recent years because of its simplicity and obvious effect. The most commonly used surgical method is to use a silicone rubber substance as a filler and implant it on the mandibular membrane to achieve the goal. The key is to carefully check and measure before operation, and the attending physician should choose and carve the shape and size of the implant and the position of the cavity bag formed at the implant site, so as to achieve the correct effect. So the skill and experience of surgeons are very important. The operation is carried out through an incision in the oral cavity under local anesthesia and can be completed in about half an hour. The mandibular fixation band should be used for three days after operation to reduce its swelling and prevent the implant from shifting. Incision suture 10 days can remove stitches. There will be discomfort in the mouth and jaw in a short time after operation, and they will gradually adapt. Pay attention to oral hygiene, diet and exercise to prevent excessive movements. You can't shake your face for weeks!
