Sports safety guidelines for children, adolescents, and adults can prevent some injuries that lead to septal hematoma. Avoiding use of illegal drugs can eliminate hematomas caused by snorting. A person who is taking anticoagulants should have routine blood tests to check the ability of the blood to clot.
Some of the long-term effects of hematomas of the nasal septum include decay of the septum, which would put a hole in the septum, and anemia from blood loss. A hole in the nasal septum allows air to pass from side to side within the nostrils. Most people, however, have no problems once the hematoma has gone away.
Hematomas of the nasal septum are not contagious and cannot be spread from person to person.
