By Dr. Raj Bhayani, ENT Specialist

If you've dealt with a chronically blocked nose but every exam, allergy test, and course of medication has come back "normal," the answer might not be inflammation at all. It might be structural. Concha bullosa is one of the most common and most commonly missed structural causes of nasal congestion, and because it doesn't show up on a basic nasal exam, it's often overlooked for years.

As an ENT, I see this pattern often: a patient who has tried nasal sprays, antihistamines, and allergy treatments with little relief, only to find on a CT scan that the real problem was an air-filled turbinate crowding their nasal passage all along.

In this guide, I'll explain what concha bullosa is, how it blocks breathing, the symptoms it causes, how it's diagnosed on imaging, and the treatment options that actually resolve it.

What Concha Bullosa Is

Concha bullosa refers to an air-filled turbinate most often the middle turbinate, a small shelf-like structure inside the nose that normally helps humidify and filter the air you breathe. In concha bullosa, an air pocket forms inside this turbinate, causing it to become enlarged and balloon-like.

This isn't an infection, a tumor, or a sign of disease. It's a normal anatomical variation that a surprising number of people are born with or develop over time. The problem isn't the air pocket itself it's the extra size it gives the turbinate, which can crowd the narrow nasal passage and interfere with normal airflow and drainage.

Why It's So Often Overlooked

Because concha bullosa is a structural variant rather than an active disease process, it doesn't cause redness, discharge, or the classic signs doctors look for during a quick nasal exam. Many patients are treated for allergies or chronic sinusitis for years before a CT scan finally reveals the real cause of their blocked nose.

How Concha Bullosa Blocks Breathing

Understanding nasal congestion from concha bullosa starts with understanding the tight geometry inside the nose. The middle turbinate sits right next to the natural drainage pathways of several sinuses. When it becomes enlarged due to an air-filled turbinate, there's simply less room for air to pass and for mucus to drain normally.

An enlarged turbinate can push against the nasal septum, narrow the space where sinuses drain, or block airflow on one side more than the other. Over time, this crowding can also make a person more prone to sinus infections, since normal drainage is being physically obstructed.

The Role of the Middle Turbinate

The middle turbinate is positioned at a critical junction point for several sinus drainage pathways. When concha bullosa is present, even a modest amount of extra size in this one structure can have an outsized effect on airflow and drainage for the whole nasal cavity.

Common Contributing Factors in Concha Bullosa Congestion

A naturally large air pocket within the turbinate

A deviated septum pressing the turbinate further into the airway

Chronic inflammation that adds swelling on top of the structural crowding

No identifiable trigger in many patients it's simply how the anatomy formed

Symptoms of Concha Bullosa

The symptoms of concha bullosa often look identical to ordinary congestion, which is exactly why it's so easy to misattribute to allergies or a lingering cold.

Blocked Nose Cause Signs to Watch For

Chronic nasal blockage that doesn't improve with allergy medication

Congestion that's noticeably worse on one side

A feeling of pressure or fullness around the cheeks or forehead

Frequent or recurring sinus infections

Less Obvious Symptoms

Mild headaches related to sinus pressure

Snoring or mouth breathing at night due to blocked airflow

Reduced sense of smell in more significant cases

Symptoms that persist despite consistently normal-looking nasal exams

Because concha bullosa doesn't always cause dramatic symptoms, many patients simply adapt to breathing through one side of their nose or living with mild chronic congestion, not realizing there's a specific, correctable structural cause.

Diagnosing Concha Bullosa on Imaging

Because concha bullosa is a structural finding, it's usually invisible on a basic in-office nasal exam and only becomes clear with the right imaging.

Nasal Endoscopy

An ENT will often start with a nasal endoscopy, a thin camera that provides a direct look inside the nasal passages. This can reveal an enlarged turbinate, but it doesn't always show the full extent of the air pocket inside it.

CT Scan Findings for Concha Bullosa

A CT scan of the sinuses is the most reliable way to confirm concha bullosa. On imaging, it clearly shows:

An air-filled cavity within the middle turbinate

The degree of crowding against the septum or nearby sinus drainage pathways

Whether the concha bullosa is contributing to sinus blockage or infection

Any additional structural issues, such as a deviated septum, occurring alongside it

Treatment for Concha Bullosa

Not every case of concha bullosa needs treatment. Many people have this variation with no symptoms at all, and it's simply noted incidentally on a scan done for another reason. Treatment becomes relevant when it's clearly contributing to congestion, recurring infections, or breathing difficulty.

Conservative Management

For milder cases, nasal steroid sprays and allergy management can reduce swelling and improve airflow around the enlarged turbinate, even though they don't change its underlying structure.

Concha Bullosa Surgery

When symptoms are significant or conservative treatment hasn't helped, concha bullosa surgery is typically recommended. This is usually performed endoscopically and involves reducing the size of the air-filled turbinate often by removing or reshaping the outer portion of the bone and lining while preserving its normal function.

This procedure is frequently combined with septoplasty if a deviated septum is contributing to the blockage, addressing both structural issues in a single surgery.

What Recovery Looks Like

Concha bullosa surgery is typically an outpatient procedure

Most patients notice improved airflow within a few weeks

Mild swelling and congestion right after surgery are normal and temporary

Follow-up visits confirm healing and normal nasal airflow

Endoscopic concha bullosa surgery reducing enlarged turbinate

Conclusion

Concha bullosa is one of those conditions that hides in plain sight. It doesn't cause the redness or visible signs that typically prompt a quick diagnosis, and because it's structural rather than inflammatory, it can go unrecognized through round after round of allergy treatment. But once it's identified usually through a CT scan it's a very treatable cause of chronic congestion.

If you've been dealing with a blocked nose that isn't responding to the usual treatments, especially if it's worse on one side or comes with recurring sinus infections, it's worth asking your ENT specifically about structural causes like concha bullosa. A scan can settle the question quickly, and treatment whether conservative or surgical can make a meaningful difference in how you breathe.

FAQs About Concha Bullosa

1. What is concha bullosa? Concha bullosa is an air-filled pocket within a nasal turbinate, most often the middle turbinate, that causes the turbinate to become enlarged and crowd the nasal passage.

2. Is concha bullosa dangerous? No, it's a normal anatomical variation rather than a disease. It only becomes a concern when it's large enough to interfere with breathing or sinus drainage.

3. Why don't regular exams catch concha bullosa? Because it's a structural finding inside the turbinate rather than visible inflammation or infection, it's usually only confirmed with imaging like a CT scan, not a basic nasal exam.

4. What are the main symptoms of concha bullosa? The most common signs are chronic nasal blockage, congestion that's worse on one side, sinus pressure, and recurring sinus infections.

5. How is concha bullosa diagnosed? Diagnosis typically involves a nasal endoscopy along with a CT scan of the sinuses, which clearly shows the air pocket within the turbinate and how much it's crowding the nasal passage.

6. Does concha bullosa always require surgery? No. Many cases are mild or symptom-free and don't need treatment. Surgery is generally reserved for cases where it's clearly causing significant congestion or recurring infections.

7. What does concha bullosa surgery involve? It's typically performed endoscopically to reduce the size of the enlarged turbinate, and it's often combined with septoplasty if a deviated septum is also contributing to the blockage.

8. Can concha bullosa cause sinus infections? Yes. By crowding nearby sinus drainage pathways, an enlarged turbinate can make normal drainage more difficult, which raises the risk of recurring infections.

9. Is concha bullosa the same as a deviated septum? No, though they often occur together. A deviated septum is a shift in the central nasal wall, while concha bullosa is an air-filled enlargement of the turbinate itself.

10. When should I see a specialist about chronic congestion? If your congestion persists despite allergy treatment, is worse on one side, or comes with frequent sinus infections, it's worth having an ENT evaluate for structural causes like concha bullosa.

Don't let chronic nasal obstruction affect your quality of life any longer.

Why “Blocked Nose” Doesn’t Always Mean Blocked Airflow

The importance of objective testing in nasal breathing

Many patients come to clinic saying they have a “blocked nose” or “nasal congestion.” It is one of the most common symptoms in ENT practice. Yet what patients describe as congestion can mean very different things medically.

Some patients truly have restricted airflow through the nose, while others have a sensation of stuffiness caused by inflammation, mucus, or nerve signalling in the nasal lining. These two problems feel similar, but they are not the same — and they require very different treatments.

At the Sydney ENT Clinic NoseLab, we use specialised testing to determine whether a patient’s symptoms are caused by real airflow obstruction or by other nasal conditions. This distinction is critical before recommending treatments such as medication, allergy therapy, or surgery.

Nasal congestion vs nasal obstruction: not the same thing

Patients often use the word “congestion” to describe several different sensations:

difficulty breathing through the nose

pressure in the face or sinuses

a “stuffy” or heavy feeling

mucus in the nose or throat

However, these symptoms do not always reflect a physical blockage of airflow.

Research comparing patient and doctor interpretations of “nasal congestion” shows that patients often associate it with pressure, mucus, or headaches, whereas clinicians define congestion primarily as reduced airflow through the nose.

Understanding this difference is essential because treatments aimed at improving airflow (such as septoplasty or nasal valve surgery) may not help symptoms caused by inflammation or nerve signalling.

How the nose senses airflow

The sensation of nasal breathing is not produced by airflow sensors. Instead, it is generated by cooling of the nasal lining as air passes through it.

Cold-sensitive receptors in the trigeminal nerve (TRPM8 receptors) detect this cooling effect and signal to the brain that airflow is present.

Medicine today outline_RJH_edit…

This explains several common experiences:

Menthol or eucalyptus inhalers can make the nose feel clearer without actually improving airflow.

Allergic inflammation or thick mucus can make the nose feel blocked even when airflow is normal.

Patients sometimes feel severe obstruction despite adequate nasal airway space.

In other words, perception and physiology do not always match.

Why objective testing matters

Because symptoms alone can be misleading, objective testing is increasingly important in nasal medicine.

At the NoseLab we combine:

detailed nasal endoscopy

functional airflow testing

physiological assessment of nasal resistance

These tools allow us to determine whether symptoms are caused by:

Structural obstruction Examples include septal deviation, nasal valve narrowing, or turbinate enlargement.

Inflammatory congestion Often related to allergy, rhinitis, infection, or environmental irritants.

Functional or sensory disorders Where the perception of airflow does not correspond with measurable airflow.

Objective testing helps prevent unnecessary surgery and ensures the correct treatment is chosen.

Rhinomanometry: measuring nasal airflow

One of the most useful tools for evaluating nasal breathing is rhinomanometry.

This test measures:

airflow through each side of the nose

pressure changes during breathing

nasal airway resistance

By quantifying nasal resistance during normal breathing, rhinomanometry helps distinguish:

fixed anatomical obstruction

reversible congestion caused by inflammation

It is considered one of the most reliable objective tests for evaluating nasal airflow and monitoring treatment response.

A respiratory scientist undertakes testing to determine true airflow

For example:

If airflow improves significantly after a nasal decongestant, the problem is likely inflammatory (such as allergy).

If airflow remains restricted, a structural issue such as nasal valve narrowing may be present.

This information helps guide decisions about medical therapy, allergy treatment, or surgery.

What research tells us about nasal symptoms

Interestingly, research shows that symptoms do not always correlate strongly with objective airflow measurements.

Studies from our group and others have demonstrated that patients’ perception of nasal obstruction can be influenced by multiple factors, including mucosal inflammation and even emotional health.

This highlights an important point: treating the structure of the nose alone does not always solve the problem.

Instead, effective management requires understanding the full physiological picture.

Using nasal endoscopy to identify inflammation

Nasal endoscopy provides a detailed view of the inside of the nose and sinuses.

Certain endoscopic findings can suggest allergy-driven inflammation, including:

middle turbinate oedema

watery secretions

inferior turbinate hypertrophy

These features have been shown to correlate with allergic airway disease in systematic reviews of nasal endoscopy findings.

Our research group has contributed extensively to understanding these patterns of disease.

The role of the NoseLab

The NoseLab at Sydney ENT Clinic is designed to provide comprehensive evaluation of nasal breathing using advanced diagnostic tools.

Testing may include:

rhinomanometry

nasal endoscopy

airflow resistance testing

assessment before and after decongestants

evaluation of nasal valve function

This approach allows us to move beyond simple visual examination and measure how the nose actually functions during breathing.

Rhinomanometry is the most reliable testing and measures true airflow (a & b). Nasal peak inspiratory flow (c) measures collapsibility and the shape or cross-sectiona is measured by acoustic rhinomanometry (d)

The goal is to provide patients with:

accurate diagnosis

personalised treatment plans

avoidance of unnecessary procedures

When should you consider objective testing?

Objective nasal airflow testing can be helpful if you experience:

persistent nasal blockage despite treatment

poor sleep related to nasal breathing

ongoing symptoms after nasal surgery

uncertainty about whether surgery may help

complex symptoms where scans appear normal

Understanding whether symptoms reflect true airflow obstruction or inflammatory congestion is the first step toward effective treatment.

Many patients are unsure whether their nasal congestion is caused by true airflow obstruction or by inflammation within the nose. The following questions address common concerns about nasal breathing and objective airflow testing.

Frequently Asked Questions About Nasal Congestion and Nasal Airflow Testing

What is the difference between nasal congestion and nasal obstruction?

Nasal congestion and nasal obstruction are often used interchangeably, but they are not the same. Nasal obstruction refers to a physical restriction of airflow through the nose, usually caused by structural problems such as a deviated septum or nasal valve narrowing. Nasal congestion, however, often refers to the sensation of a blocked or stuffy nose caused by inflammation, mucus, or swelling of the nasal lining. Many patients feel congested even when airflow through the nose is normal.

How can doctors measure whether my nose is actually blocked?

Doctors can objectively measure nasal airflow using specialised tests such as rhinomanometry. This test measures the pressure and airflow through each side of the nose during normal breathing. By calculating nasal airway resistance, rhinomanometry helps determine whether symptoms are caused by a true airflow obstruction or by inflammatory congestion from conditions such as allergy or rhinitis.

What is rhinomanometry?

Rhinomanometry is a diagnostic test used to measure nasal airflow and nasal resistance during breathing. It works by measuring the pressure difference between the front and back of the nose while airflow is recorded. The results show whether the nasal airway is physically restricted and whether the obstruction improves after using a nasal decongestant.

Why do some people feel blocked even when their nose is open?

The sensation of nasal breathing depends largely on cooling of the nasal lining as air flows through it. Nerve receptors in the nose detect this cooling effect and signal the brain that airflow is present. When inflammation, mucus, or swelling interfere with this cooling sensation, patients may feel congested even if airflow is normal.

Can allergy cause nasal congestion without blocking airflow?

Yes. Allergic rhinitis and other inflammatory conditions can cause swelling of the nasal lining, increased mucus production, and nerve irritation. These changes can create a strong sensation of congestion even when the airway remains relatively open.

When should someone consider objective nasal airflow testing?

Objective testing may be helpful if you experience:

persistent nasal blockage despite treatment

difficulty breathing through the nose during sleep

ongoing symptoms after previous nasal surgery

uncertainty about whether surgery may improve breathing

symptoms of nasal congestion despite normal scans or examinations

Testing helps determine whether symptoms are due to structural obstruction or inflammatory congestion.

Can nasal airflow testing help decide if surgery is necessary?

Yes. Objective airflow testing can help determine whether surgery is likely to improve breathing. If testing shows that airflow obstruction is caused by structural narrowing, procedures such as septoplasty or nasal valve surgery may help. If airflow is normal, treatment may instead focus on allergy control or medical therapy.

What tests are performed in a specialised nasal airflow laboratory?

In a specialised nasal function clinic such as the NoseLab, testing may include:

rhinomanometry to measure airflow resistance

nasal endoscopy to visualise internal structures

nasal airflow measurements before and after decongestants

evaluation of nasal valve function

assessment of inflammatory conditions such as allergy or rhinitis

These tests help provide a comprehensive evaluation of nasal breathing.

Why is my nose always blocked at night?

Many people notice that their nose feels more blocked when lying down at night. This occurs because body position changes blood flow to the nasal lining. When you lie down, increased venous pressure causes the turbinates (structures inside the nose) to swell slightly. This is part of the normal nasal cycle, where one side of the nose becomes more congested while the other opens. In people with allergy, inflammation, or structural narrowing, this normal cycle can become exaggerated and produce significant nighttime congestion.

Can a deviated septum cause nasal congestion?

Yes. A deviated septum, where the cartilage or bone dividing the nasal passages is off-centre, can narrow one or both sides of the nasal airway and reduce airflow. However, many people with septal deviation breathe normally and do not experience symptoms. Nasal congestion is often caused by inflammation from allergy or rhinitis rather than septal anatomy alone. Objective airflow testing can help determine whether a septal deviation is actually responsible for breathing problems.

Why does menthol make my nose feel clearer?

Menthol and similar substances stimulate cold-sensitive nerve receptors in the nasal lining. These receptors signal to the brain that air is moving through the nose, creating a sensation of improved airflow. However, menthol usually does not change the physical size of the nasal airway or improve airflow resistance. It simply alters the perception of breathing, which is why products containing menthol, eucalyptus, or similar compounds can make the nose feel clearer without treating the underlying cause of congestion.
