SWELLING: Swelling is a normal occurrence after surgery and will not reach its maximum until 2-3 days after surgery. It can be minimized by using a cold pack, ice bag or a bag of frozen peas wrapped in a towel and applied firmly to the cheek adjacent to the surgical area. This should be applied twenty minutes on and twenty minutes off during the first 24 hours after surgery.

The reason for icing is to decrease inflammation and/or pain in the affected area. The way it works is the ice lowers body temperature around the affected area, decreasing blood flow which in turn helps to reduce swelling.
