Nasal polyps form in the nose or sinuses and look like gray-white bubbles or teardrops. Unless the polyp is large and has grown down close to the opening of the nose, it is difficult to see polyps without the assistance of specialized medical equipment. Most polyps are present on both sides of the nose/sinuses, and if they’re not, further investigation to rule out cancer/pre-cancer growth should be done.Make An Appointment
About 12% of all adults suffer from chronic rhinosinusitis, and 20% of those people have nasal polyps.

About Nasal Polyps
Anyone can get nasal polyps, but they are more common in adults, people with cystic fibrosis, those with reactions to aspirin and non-steroidal anti-inflammatory drugs (NSAIDs, like ibuprofen), and people with Allergic Fungal Rhinosinusitis (AFRS).
There may be a hereditary link for nasal polyps, and those with asthma may also be at risk for having nasal polyps. What exactly causes nasal polyps is still unclear.
Not everyone has symptoms associated with nasal polyps. However, if you are experiencing breathing problems, a cold that just won’t go away, decreased sense of smell, or frequent sinus infections, you should seek advice from your provider or an allergy specialist. You may have nasal polyps.
Unfortunately, they are not completely harmless and may be linked to other conditions.
We still don’t know exactly what causes nasal polyps to develop and grow. In western populations, eosinophils, a type of allergy cell, appears to play a role, as does the bacteria Staphylococcus aureus.
Some researchers also believe nasal polyps occur because of specific characteristics of one’s immune system or the chemical make-up of one’s nose and sinus walls. However, more research is required.
When you meet with one of our allergy specialists, they will ask you questions about your medical history and perform a physical exam. He/she may also look into your nose with a special tool called a rhinoscope, or nasal endoscope, which is a thin, flexible tube with a small camera at the end.
Treatment for nasal polyps usually begins with a steroid nasal spray to shrink the nasal polyps. Your provider may also prescribe short-term oral corticosteroids, such as prednisone, but it should be used cautiously due to steroid side effects.
Saline sinus rinses and antileukotriene medications are also frequently recommended. For those who have aspirin or NSAID sensitivities, aspirin desensitization may also shrink the nasal polyps. Biologics are a class of medications more recently approved to treat nasal polyps.
Unfortunately, nasal polyps tend to come back, so you may need to keep using your polyp medications long-term and get checkups with a nasal endoscope every now and then.
Nasal Polyps Symptoms
You may have nasal polyps and not experience any symptoms, especially if the polyps are small. If you do have symptoms, they may include:
- Breathing through your mouth, which may present as snoring or sleep apnea
- Decreased or lost sense of smell and/or taste
- Facial pressure or pain, including pain in upper teeth
- Constant runny nose, or post-nasal drainage/drip
- Frequent asthma attacks if you have asthma
- Frequent sinus infections
- Nasal congestion or stuffy nose
If you suffer from conditions that trigger inflammation of the nasal passages and sinuses, you may be at greater risk for developing nasal polyps. Conditions that are often associated with nasal polyps include:
Allergic Fungal Rhinosinusitis (AFRS)
Eosinophilic Granulomatosis with Polyangiitis (EGPA)
Because nasal polyps can block your airflow and keep your nose and sinus from draining properly, left untreated they can cause complications that include:
- Chronic sinus infections
- Asthma flare-ups (for those who have asthma)
- Obstructive sleep apnea
Nasal Polyps Surgery
Depending on the severity of your nasal polyps, your provider may recommend surgery by an ENT specialist to remove the polyps. The type of surgery depends on the size of the polyp.
A polypectomy is an outpatient surgery done with a small suction device or a microdebrider that cuts and removes soft tissue, including the mucosa.
For larger polyps, your doctor can perform an endoscopic sinus surgery using a thin, flexible endoscope with a tiny camera and small tools on the end. Your doctor will guide the endoscope into your nostrils, find the polyps or other obstructions, and remove them. Your doctor may also enlarge the openings to your sinus cavities.
Nasal Polyps FAQ
Are nasal polyps dangerous?
Nasal polyps alone are not considered a dangerous health condition. They can cause additional health conditions, such as sleep apnea and chronic sinusitis, which can then cause additional, more dangerous health issues.
Can nasal polyps be cancerous?
Nasal polyps are not cancerous, but they can be mistaken for growths that are cancerous or pre-cancerous. A medical provider needs to analyze your polyps to make a definitive diagnosis. There is no evidence that nasal polyps are life-threatening.
Can a nasal polyp fall out?
No, they must be surgically removed
Can you remove nasal polyps with tweezers?
No, they must be surgically removed as they are under the deep skin layers of the nose. Removal of nasal polyps can cause bleeding and puncture of the surrounding nasal passage and should be performed by a trained surgeon.
What is the long-term outlook after surgery for nasal polyps?
With surgical treatment, most symptoms get significantly better. However, if you’ve lost some sense of smell, it may never return. Even with surgery, nasal polyps may regrow in up to 30-40 percent of people after 6 months to a year.
