You can usually eat normally 1-2 weeks after jaw angle surgery, but you should be careful to avoid eating overly hot food. Currently, jaw angle surgery is performed using intraoral incisions, so it is especially important to maintain oral hygiene after surgery. Generally, 6 hours after surgery, you can eat milk, juice, broth and other liquid food, and 12 hours later, you can take in semi-liquid food, such as sour milk, egg custard, thin rice, etc. It usually takes about 1-2 weeks to gradually transition to a normal diet. During the recovery period, patients should avoid eating cold, spicy and other stimulating foods, and should not eat foods that are too hot or too hard, prohibit smoking and drinking, and gargle with mouthwash after each meal to avoid food residues staying near the wound and causing secondary infection. If there is blood crust or secretion on the wound, sterile saline can be used to wipe it. After jaw angle surgery, a local pressure bandage will be used to shape the face, and patients should not loosen the gauze at their own discretion. The swelling of the face will appear in the first 2 weeks after surgery, cold compresses can be applied to promote the swelling, and the swelling can be completely reduced in about 1 month, and the contour of the face can be revealed in 1-2 months, and the best effect can be achieved in 3-6 months, and it is basically in a stable state after half a year.
