If you have been dealing with ongoing sinus symptoms, you may hear two terms come up together: nasal polyps and chronic sinusitis. Although they are closely related, they are not the same condition.

Nasal polyps are soft, noncancerous growths associated with chronic inflammation, while chronic sinusitis, more accurately called chronic rhinosinusitis, is a long-term inflammatory condition affecting the nose and sinuses. Some people have chronic rhinosinusitis without polyps, while others develop polyps as part of their disease.

Understanding this connection can help explain why sinus symptoms sometimes persist and why treatment may vary from one person to another.

Are Nasal Polyps a Type of Sinusitis?

Nasal polyps are growths that can develop as part of chronic rhinosinusitis.

Chronic rhinosinusitis involves persistent inflammation of the nose and sinuses, generally accompanied by symptoms lasting at least 12 weeks and objective evidence of inflammation.

Doctors distinguish between two forms of the condition:

• Chronic rhinosinusitis without nasal polyps (CRSsNP)
• Chronic rhinosinusitis with nasal polyps (CRSwNP)

This distinction helps guide diagnosis and treatment because the two forms can have different characteristics and treatment needs.

Why Do Nasal Polyps Develop with Chronic Sinus Disease?

Nasal polyps develop in association with ongoing inflammation in the nasal and sinus lining. The exact causes are not fully understood, but different inflammatory processes can contribute to their formation.

As polyps grow, they may narrow the nasal passages or obstruct sinus drainage pathways, making it harder to breathe through the nose .and harder for the sinuses to drain mucous into the nose.

However, not everyone with chronic rhinosinusitis develops polyps. They are also not simply the result of an untreated sinus infection. Their development involves a complex combination of inflammatory and individual factors. In fact, many of the factors that cause polyps also cause lower airway inflammation such as asthma.

Can Nasal Polyps Make Sinus Problems Worse?

Yes. Nasal polyps can contribute to ongoing nasal and sinus symptoms by obstructing the nasal passages or sinus drainage pathways.

Common symptoms include:

• Persistent nasal congestion
• Difficulty breathing through the nose
• Reduced or lost sense of smell
• Nasal drainage or postnasal drip
• Facial pressure or discomfort

These symptoms can also occur with chronic rhinosinusitis without polyps, so symptoms alone cannot determine whether polyps are present. A nasal examination and, when appropriate, additional testing like a simple nasal endoscopy, can help establish the diagnosis.

Why Do Some People Have Polyps and Others Don't?

Not everyone with chronic rhinosinusitis develops nasal polyps. Why some people do and others don't isn't fully understood, but differences in inflammation appear to play an important role. Conditions such as asthma are also more commonly associated with chronic rhinosinusitis with nasal polyps.

Allergies and environmental exposures may contribute to nasal inflammation in some people, but they aren't the only factors involved.

This is one reason sinus symptoms can look similar from person to person, even when the underlying cause or findings during an examination are different. Treatment may need to be tailored accordingly.

How Are Nasal Polyps and Chronic Sinusitis Treated?

The right treatment depends on what's causing the symptoms, how severe they are, whether nasal polyps are present, and how well previous treatments have worked.

Care may include saline irrigation, nasal corticosteroid sprays, steroid sinus irrigations, or other medications like biologics when appropriateD. If symptoms continue despite appropriate medical treatment, endoscopic sinus surgery may be an option. For a closer look at when surgery may be considered, read our guide to when to consider surgery for chronic sinusitis.

Surgery can remove polyps and open blocked sinus pathways, but it doesn't always resolve the inflammation that contributed to their development. That's why some people need continued medical treatment and follow-up after surgery to help manage symptoms and reduce the chance of polyps returning.

A rhinologist can assess the nose and sinuses, discuss the available options, and help determine which approach best fits the patient's needs.
