1. General treatment: pay attention to rest after surgery, keep the operated part dry and clean, prohibit smoking and alcohol, and eat more vegetables and fruits. 2. Postoperative pain: Pain at the wound can appear after the anesthesia wears off, and it will gradually decrease 1-2 days after surgery. If the pain is severe or progressively aggravated, it is necessary to consult a doctor in time. 3. Prevention of infection: antibiotics can be applied for 1-3 days after surgery as appropriate. 4. Postoperative medication change: start medication change on the 2nd and 3rd day after surgery, and change medication regularly according to the doctor’s arrangement. Try to go to regular hospitals or outpatient clinics for medication change. If you find redness, swelling, pus and severe pain in the wound, you need to return to the hospital for follow-up in time. 5.For patients with high nasal, perinasal and oil secretion, after 3 days after surgery, it is not necessary to continue to use gauze or band-aid to dress the wound, and the wound exposure is beneficial to avoid local accumulation of oil causing wound infection. 6.Post-operative suture removal: return to the hospital to remove the front line at the prescribed time according to the surgeon’s requirements. Head and facial incisions can be removed about 7 days after surgery.
