Understanding the difference between rhinitis and rhinosinusitis can help you recognize your symptoms and find the right treatment.
Both conditions can cause nasal congestion, drainage, and difficulty breathing through the nose. However, they affect different areas and can have different causes.
Rhinitis mainly affects the nasal passages, while rhinosinusitis affects the nose and sinuses. Rhinitis is often linked to allergies, while rhinosinusitis can develop from infections, inflammation, allergies, or problems that prevent the sinuses from draining properly.
What Is Allergic Rhinitis?
Rhinitis occurs when the lining inside the nose becomes inflamed. Allergic rhinitis happens when your immune system reacts to an allergen, such as pollen, dust mites, or pet dander.
Common symptoms include:
- Sneezing
- Runny nose
- Itchy nose
- Nasal congestion
- Watery or itchy eyes
- Postnasal drip
- Nasal obstruction
Allergic rhinitis can be seasonal or year-round, depending on the allergens that trigger your symptoms.
For example, seasonal allergies may cause symptoms during certain times of the year when pollen levels are high. Year-round symptoms may be linked to indoor allergens such as dust mites or pet dander.

What Is Rhinosinusitis?
Rhinosinusitis, often called sinusitis, is inflammation of the nasal passages and sinuses.
The sinuses are air-filled spaces around the nose, cheeks, and forehead. When the tissues inside the nose and sinuses become swollen, mucus may not drain properly.
Rhinosinusitis can cause:
- Facial pain or pressure
- Nasal congestion
- Thick nasal drainage
- Postnasal drip
- Reduced sense of smell
- Cough
- Headache
- Sore throat
Rhinosinusitis can be caused by a viral infection, bacterial infection, allergies, or other factors that affect normal sinus drainage.

Acute vs. Chronic Rhinosinusitis
Rhinosinusitis can be classified based on how long symptoms last:
- Acute rhinosinusitis: Symptoms last less than 4 weeks.
- Chronic rhinosinusitis: Symptoms continue for more than 12 weeks.
- Recurrent acute rhinosinusitis: Multiple episodes of acute rhinosinusitis occur with periods of improvement between episodes.
Chronic rhinosinusitis is a long-term inflammatory condition. It may occur with or without nasal polyps and often requires a more detailed evaluation. Current guidelines recommend confirming chronic rhinosinusitis with objective evidence of inflammation, such as nasal endoscopy or CT imaging when appropriate.
Rhinitis vs. Rhinosinusitis: Causes and Risk Factors
Rhinitis and rhinosinusitis can have some similar triggers, but they are not the same condition.
Common Causes of Rhinitis
Allergic rhinitis is usually caused by an immune response to allergens such as:
- Pollen
- Dust mites
- Pet dander
- Mold
Nonallergic rhinitis can have other triggers, including environmental irritants, changes in temperature, strong odors, or certain medications.
Common Causes of Rhinosinusitis
Rhinosinusitis can develop when inflammation or infection affects the nasal passages and sinuses.
Possible causes and risk factors include:
- Viral infections, such as the common cold
- Bacterial infections
- Allergies
- Nasal polyps
- A deviated septum
- Other structural problems that affect sinus drainage
- Environmental irritants
When the nasal passages become swollen, the normal drainage of mucus from the sinuses can become blocked. This can contribute to sinus symptoms.
Key Differences Between Rhinitis and Rhinosinusitis
Although rhinitis and rhinosinusitis can cause similar nasal symptoms, there are some important differences.
| Rhinitis | Rhinosinusitis |
|---|---|
| Mainly affects the nasal passages | Affects the nose and sinuses |
| Often caused by allergies or irritants | Can be caused by infection, inflammation, allergies, or drainage problems |
| Sneezing and an itchy nose are common | Facial pressure, thick drainage, and reduced smell may be more common |
| Watery eyes may occur with allergies | Cough and postnasal drip may occur |
| Can be seasonal or year-round | Can be acute, chronic, or recurrent |
The symptoms can overlap, so a healthcare professional may need to evaluate your symptoms to determine the cause.
How Is Rhinitis Treated?
Treatment for rhinitis depends on the cause and severity of your symptoms.
Common treatment options include:
Avoiding Triggers
If allergies are causing your symptoms, reducing exposure to known allergens can help.
For example:
- Keep dust levels low.
- Reduce exposure to pet dander when possible.
- Keep windows closed when outdoor pollen counts are high.
- Use appropriate air filtration.
- Identify specific allergens through allergy testing when recommended.
Medications
Depending on your symptoms, a healthcare provider may recommend:
- Antihistamines
- Nasal corticosteroids
- Nasal antihistamines
- Other medications to control nasal symptoms
Intranasal corticosteroids are considered a preferred treatment for persistent allergic rhinitis.
Allergy Immunotherapy
People with persistent allergic rhinitis may benefit from allergy immunotherapy.
Allergy shots or certain forms of sublingual immunotherapy can gradually reduce sensitivity to specific allergens.

Treatment for Chronic Rhinitis
Some people continue to experience a runny nose or congestion even after addressing common allergy triggers.
Treatments such as RhinAer may be an option for certain patients with chronic rhinitis. This procedure targets nerves involved in excessive nasal secretions.
An ENT specialist can determine whether this type of treatment is appropriate for you.
How Is Rhinosinusitis Treated?
Treatment for rhinosinusitis depends on the cause, duration, and severity of symptoms.
Saline Nasal Irrigation
Saline rinses can help clear mucus and irritants from the nasal passages.
Your healthcare provider can show you how to use nasal irrigation safely.
Nasal Medications
Nasal corticosteroids may help reduce inflammation and improve nasal symptoms.
Other medications may be recommended based on the cause of your symptoms.
Antibiotics
Antibiotics are not needed for every case of sinusitis.
Many cases of acute rhinosinusitis are related to viral infections and improve without antibiotics. Healthcare providers may consider antibiotics when symptoms suggest acute bacterial rhinosinusitis, such as symptoms that persist without improvement for at least 10 days or symptoms that worsen after initially improving.
Surgery
Some people with chronic or recurrent sinus problems may need a procedure to improve sinus drainage.
Depending on the underlying problem, treatment may include:
- Balloon sinuplasty
- Endoscopic sinus surgery
- Treatment for nasal polyps
- Correction of structural problems affecting nasal or sinus drainage
Learn more about balloon sinuplasty.
How Can You Prevent or Manage Symptoms?
You may be able to reduce nasal and sinus symptoms by making a few changes to your daily routine.
Try these strategies:
- Avoid known allergens and irritants.
- Keep your home clean and reduce dust buildup.
- Use saline nasal rinses when appropriate.
- Stay hydrated.
- Avoid smoking and secondhand smoke.
- Get enough rest.
- Follow your healthcare provider’s treatment plan.
- Manage known allergies before symptoms become severe.
If allergies are contributing to repeated sinus symptoms, treating the underlying allergies may also help. Allergic rhinitis and chronic rhinosinusitis can occur together, so identifying the cause of your symptoms is important.
When Should You See an ENT Specialist?
Occasional nasal congestion or a runny nose may not require an ENT visit. However, you should consider seeing a healthcare professional if your symptoms:
- Last for several weeks
- Keep coming back
- Interfere with sleep or daily activities
- Cause significant facial pain or pressure
- Affect your sense of smell
- Do not improve with usual treatments
- Continue for more than 12 weeks
Chronic rhinosinusitis requires more than simply having ongoing nasal symptoms. An ENT specialist can evaluate your symptoms and look for signs of inflammation, nasal polyps, or structural problems.
