Beijing Shengjiarong Facial Sculpture Center reminds you to rest and recuperate for at least 7 days after mandibular angle surgery. Because the wound will heal after mandibular angle surgery for a period of time, smoking, spicy, irritating and cold things are forbidden during this period. In particular, do not do strenuous exercise or blow cold air, which may affect the healing time. After mandibular angle surgery, you should be hospitalized for 3-5 days, and you can return to normal work in about 10 days. The effect of mandibular angle surgery will appear after 6 months. I don't eat hard food or laugh for a month.
