nasal polyp

A pedunculated polyp of the nasal mucosa. See: illustration

Nasal polyps are the most commonly identified nonmalignant tumor of the nasal passages. They are more commonly identified in men than in women.


The most common symptom of nasal polyposis is obstruction to the flow of air into and out of the nasal passages.


Steroid nasal sprays may improve airflow through the nasal passages. Surgical removal of polyps may occasionally be necessary when medical treatment is unsuccessful.
