What routine examinations do you need to do before facial plastic surgery? Ensure that you are healthy and can withstand surgery. Whether it is a major operation or a minor operation, you need to check the electrocardiogram, take a chest X-ray, understand the lung function, check the liver and kidney function, understand the liver function, and have a blood test to see if your blood has any blood diseases. Check the blood coagulation function to see if you have any diseases that affect bleeding. This is the first exam. Don't abuse drugs. If you don't feel well, seek medical advice in time.
