Nasal polyps are soft, painless growths on the lining of your nasal passages or sinuses. They hang down like teardrops or grapes.
Nasal polyps are from chronic inflammation and are associated with asthma, recurring infection, allergies, drug sensitivity or certain immune disorders.
Symptoms may include:
post nasal drip
Nasal polyps associated with irritation and swelling of the lining of your nasal passages and sinuses that lasts more than 12 weeks are symptomatic of chronic sinusitis.
Symptoms of chronic sinusitis with nasal polyps include:
a runny nose
decreased or absent sense of smell
loss of sense of taste
facial pain or headache
pain in your upper teeth
a sense of pressure over your forehead and face
Your doctor can usually make a diagnosis based on your symptoms, a general physical exam, and an examination of your nose. Polyps may be visible with the aid of a nasal endoscope which is a narrow tube with a lighted magnifying lens or tiny camera used to perform a detailed examination inside the nose and sinus.
