What Is a Nasal Polyp?
Nasal polyps are abnormal, non-cancerous growths that form as soft, swollen sacs within the inflamed tissue of the nose and sinuses. These growths can line the nasal cavity and sinuses, and when they become large enough, they can block the airways and cause breathing difficulties. Nasal polyps are considered a subtype of chronic rhinosinusitis, a condition in which the nasal cavity and sinuses remain inflamed and obstructed over a long period. However, not everyone with chronic rhinosinusitis goes on to develop nasal polyps.
These growths are relatively common, and anyone can develop them. While some types of cellular growths can be cancerous, a nasal polyp itself is not cancerous.
Causes and Risk Factors of Nasal Polyps
Researchers are still studying the exact causes of nasal polyps. These growths tend to be more common in people who have the following conditions:
- Asthma
- Aspirin sensitivity
- Chronic sinus infections
- Cystic fibrosis
- Hay fever (allergic rhinitis)
In addition, certain genes involved in the immune system and inflammatory responses may contribute to the formation of nasal polyps. If members of your family have had nasal polyps, your own likelihood of developing them is also higher.
What Are the Symptoms of Nasal Polyps?
People with nasal polyps may feel as though they have a cold that lasts for months. Common symptoms include:
- Nasal congestion (stuffiness)
- Runny nose
- A feeling of fullness in the sinuses (without pain)
- Reduced sense of smell
- A feeling of blockage and the need to breathe through the mouth
Although the symptoms of nasal polyps can resemble those of other conditions, seeing a doctor is essential to confirm an accurate diagnosis.
Are you a good candidate?
Your goal, medical condition, anatomy, and expectations for the result should all be reviewed together in an in-person evaluation.
What is a common mistake?
Deciding based only on one portfolio photo, or comparing yourself to someone else, can create unrealistic expectations.
Why does choosing the right surgeon matter?
A good outcome is not just about appearance; preserving function, safety, and a proper aftercare plan are also part of the treatment.
How Are Nasal Polyps Diagnosed?
Diagnosing nasal polyps usually begins with a review of medical history and a physical examination. The doctor may use specific instruments to view the polyps directly. In some cases, the following tests are used for a more precise diagnosis:
- Nasal endoscopy
- CT scan
- MRI
- Allergy testing
- Polyp biopsy (if necessary)
Many people with nasal polyps need to be evaluated by an ear, nose, and throat (ENT) specialist.

How Are Nasal Polyps Treated?
Treatment for nasal polyps depends on the severity of symptoms, the patient's age, and their general health. The main goal of treatment is to reduce inflammation and shrink the size of the polyps. Doctors typically begin treatment with topical steroid medications, which can help reduce inflammation. If there is no adequate response to this treatment, oral steroid medications may be prescribed.
Other treatment options include:
- Anti-leukotriene medications
- Antibiotics (when needed)
- Saline sinus rinses
- Antihistamines
- Allergen immunotherapy
If medical treatments are not effective, surgery may be a suitable option. After surgery, the use of inhaled nasal steroids is recommended to help prevent the polyps from returning.
What Are the Possible Complications of Nasal Polyps?
Nasal polyps can lead to complications such as sinus infections. In rare cases, more serious infections such as meningitis or infections around the eyes may occur. If your symptoms do not improve, be sure to see a doctor.
What Can I Do to Prevent Nasal Polyps?
There is no guaranteed way to prevent nasal polyps from forming, but following your doctor's medical treatment plan and instructions can help control them and reduce the chance of recurrence.
