After rhinoplasty, swelling usually begins at 1-2 hours and reaches its peak in about 24 hours. Method of reducing swelling after rhinoplasty: Apply antibiotic ointment to the wound after rhinoplasty. If exposed, there will be a small amount of oozing blood without dressing, which can be gently wiped off with sterilized cotton fiber. Never touch the wound with unclean things to avoid pollution.
