Suggestion: the solution of wound bleeding after alar reduction: bleeding often occurs 5 days after operation, and the bleeding site is mostly under the nasal cavity 1/3. Holding the lower 1/3 of nasal cavity and nostril by hand can effectively stop bleeding. When nosebleeds, you should take a prone position and avoid a supine position to avoid vomiting caused by blood flowing into the pharynx. Spit out the blood in your mouth, too, and don't swallow it.
