What You Should Know About a Broken Nose

6. Complications

If the nose bleeds for more than 15 minutes following a broken nose, it could be a sign of a more serious issue. A small, grape-like swelling that appears on the nasal septum 24 to 72 hours after the injury may indicate a septal hematoma. This rare but serious complication can occur as a result of nasal or facial trauma. Septal hematomas must be drained quickly by a healthcare professional to prevent infection or damage to the cartilage. Abnormalities in the tissue of the nose are signs of a deviated nasal septum. Cuts or punctures on the nose could lead to a severe infection such as meningitis or a brain abscess.
