Nasal polyps are soft, teardrop-shaped, abnormal growths on the tissue lining your sinuses or nasal passages. They’re often associated with symptoms such as a runny nose or nasal congestion.
These painless growths are not usually a sign of cancer. Most often, they are benign (noncancerous).
However, if your symptoms persist or become severe, speak with your doctor.
According to the University of Washington, about 4% of people experience nasal polyps. They’re most common in middle-aged adults but can also affect young people.
Nasal polyps can form throughout your sinuses or nasal passages, but most often are found in your sinuses near your cheekbones, eyes, and nose.
The first steps for diagnosing nasal polyps are a general physical examination and an examination of your nose. Your doctor might be able to see polyps with a nasoscope — a small instrument with a light and lens used to view the inside of your nose.
If your doctor is unable to see your nasal polyps with a nasoscope, the next step may be a nasal endoscopy. For this procedure, your doctor guides a thin tube with a light and camera into your nasal cavity.
Your doctor may also recommend a CT or MRI scan to determine the size, location, and extent of your nasal polyps’ inflammation. This helps determine the potential for cancerous growths.
Most nasal polyps are not a sign of nasal cavity or paranasal sinus cancer.
Instead, they’re typically the result of chronic inflammation from:
- allergies
- asthma
- sensitivity to drugs such as aspirin
- immune disorders
Polyps can form when tissue of the nasal mucosa — which protects your sinus and the inside of your nose — becomes inflamed.
Nasal polyps are associated with chronic sinusitis. Symptoms can include:
- postnasal drip
- stuffy nose
- losing your sense of taste
- reduced sense of smell
- pressure in your face or forehead
- sleep apnea
- snoring
If your nasal polyps are small, you may not notice them. However, if several develop or your nasal polyps are large, they may block your sinuses or nasal passages. This can lead to:
- frequent infections
- loss of sense of smell
- breathing problems
Nasal polyps are usually treated without surgery. Your doctor will prescribe medications to reduce inflammation and the size of the polyps.
To relieve symptoms, your doctor may also recommend nasal steroids such as:
- budesonide (Rhinocort)
- fluticasone (Flonase, Veramyst)
- mometasone (Nasonex)
- triamcinolone acetonide (Nasacort)
If your nasal polyps are a result of allergies, your doctor may recommend antihistamines to reduce allergy symptoms.
If nonsurgical treatment options are not effective, one common procedure is endoscopic surgery. Endoscopic surgery involves a surgeon inserting a tube with a camera and light attached to it into your nostrils and removing the polyps using small tools.
If removed, nasal polyps might return. Your doctor may recommend a routine of saline washes or a nasal spray that reduces inflammation and works to prevent reoccurrence.
Nasal polyps are usually not a sign of cancer. You may be at a higher risk of nasal polyps if you experience other conditions that cause chronic inflammation in your sinuses, such as asthma, allergies, or acute sinusitis.
While the condition does not always require treatment, speak with your doctor if symptoms persist or worsen over time. They can diagnose the cause and recommend effective treatment.
