Nasal polyps start near the Ethmoid sinuses (located at the top of the inside of the nose) and grow into the open areas. Large polyps may block the airway.
Having any of the following conditions may make people more likely to get nasal polyps:
A person suffering from nasal polyps may feel difficulty in breathing; there is constant dripping from the nose and loss of one’s sense of smell.
The doctor examines the patient’s nasal passages. A computerized tomography (CT) scan will be done to help determine the size and exact location of the polyps, including any polyps in the sinuses.
