What do we need to pay attention to in terms of personal care after jaw angle surgery? First, because of the drainage, a negative pressure drainage tube will be placed on the wound after the surgery is completed, so that the accumulated blood in the wound can be sucked out and not allowed to remain. If there is blood in the wound, it will be absorbed slowly, but at a slower pace. The drainage tube is usually removed three days after surgery. After three days, we need to remove the dressing and replace it with a headgear. Here comes the second question: How long do I need to wear the headgear? Generally speaking, we need to wear it 24 hours a day from one week to half a month after surgery. After half a month, as we need to go out to work. For aesthetic reasons, we can stop wearing it at this time. But when we go home, we still have to wear it. After a month, you can wear the headgear optionally. What do we need to pay attention to in terms of diet? Three days after surgery, our diet is mainly soft food. Especially after the cheek arch surgery, we can hardly eat hard things. You need to eat a soft diet for about three months. During this period of time, you must not bite hard continuously, otherwise it will cause fracture, bone displacement and other such situations.
