Nasal Polyps

What Are Nasal Polyps?

Nasal polyps are small, noncancerous growths that form on the lining of the nasal passages or sinuses. Small polyps may go unnoticed and require no treatment, but larger ones can obstruct the sinuses and lead to infections and breathing problems.

Chronic sinusitis, allergies and asthma are all frequently associated with nasal polyps. Symptoms include runny nose, congestion, postnasal drip, loss of smell and taste, facial pain and pressure, headache, pain in the upper teeth, itchy eyes and snoring. If symptoms last longer than ten days and are not associated with a cold or allergies, make an appointment with your doctor. If left untreated, nasal polyps can cause complications such as obstructive sleep apnea, asthma attacks, meningitis, aneurysms and blood clots.

What Causes Nasal Polyps?

It is unclear what causes nasal polyps. Some people are prone to chronic inflammation of the sinuses, and many of those individuals are predisposed to developing polyps (while others never do). There is speculation that the immune systems of people with nasal polyps behave differently.

Your doctor can diagnose polyps based on feedback regarding your symptoms and a visual examination of your nose. Diagnostic tests including nasal endoscopy, CT scan, MRI and allergy tests can help pinpoint the size and location of nasal polyps and whether they are being caused by allergies.

Nasal Polyps Treatment

To treat polyps, your doctor or ENT specialist will attempt to shrink them down to a manageable size through medications to relieve inflammation or the underlying condition responsible. Common drugs include nasal, oral or injectable corticosteroids, antihistamines and antibiotics. When medical treatment doesn’t work, surgery may be an option. Polyps are removed during an outpatient procedure called a polypectomy or via more in-depth endoscopic sinus surgery.
