1.A small amount of blood will be oozing from the incision site within 24 hours after surgery, which is a normal postoperative reaction and requires no special treatment. 2.Avoid water on the incision site within one week after surgery, keep the incision dry and clean. 3.Immediate cold compress for 15~20 minutes after surgery. If conditions allow, you can do cold compress 4~6 times within 48 hours after surgery, 15~20 minutes each time, which is helpful to improve the tissue swelling. 4.Be careful not to pull any sutures or scabs. Change the medication 2 days after surgery, and come to the hospital to remove the stitches on the 7th day after surgery. 5.Avoid smoking, alcohol and spices after surgery, and follow the doctor’s advice for postoperative medication. 6.Red and hard scars at the incision after surgery are normal physiological reactions. 7.If there is any node left after surgery, or if the sutures in the wound are exposed, please come to the clinic for removal at any time.
