After cheekbone plastic surgery, there is usually an advanced "micro-pump" analgesic instrument, which can give painkillers continuously and slightly within 48 hours after cheekbone grinding surgery. Therefore, patients do not have to worry about intraoperative discomfort and postoperative pain. If your operation is not very painful, you can take care of yourself. It is best to place a drainage strip at the surgical opening and take it out 48 hours after operation. Therefore, it is necessary to fast for two days after zygomatic grinding, mainly relying on infusion to maintain physiological needs. After cheekbone grinding surgery, patients usually need to be hospitalized for about 5 to 7 days, and then they can go home to take care of themselves, but they should follow the doctor's advice.
