1. After operation, limit mandibular movement, avoid opening mouth, give tube-fed liquid food, appease children, and prevent excessive crying, so as not to cause wound dehiscence.

2. The wound in the operation area can be exposed. Apply 75% alcohol and 3% hydrogen peroxide every day to keep the face clean and do oral care.

3. The facial skin suture is removed 5-7 days after operation, and the suture on the oral mucosa can fall off by itself or be removed two weeks later, so as to avoid premature suture removal and gaping wound.

4. Use antibiotics 3-5 days after operation to prevent infection.
