Because the bone itself has no nerves, patients will not feel pain when cutting or polishing the bone during plastic surgery with prominent mandibular angle. Usually there will be pain after mandibular grinding surgery, which is caused by soft tissue around the bone, but it will not be too intense. Usually you need to stay in hospital for 2-3 days after the operation, mainly because you have done general anesthesia during the operation. The hospitalization time is mainly to observe whether there are any adverse reactions after the general anesthesia is lifted. The above information comes from Beijing Shengjia Xinzhang, hoping to get your attention.
