Nasal Obstruction: When to See an ENT Doctor

Nasal obstruction refers to difficulty breathing through one or both nostrils. Common causes include deviated nasal septum, enlarged turbinates, nasal polyps, and allergic rhinitis. ENT doctors diagnose nasal obstruction using nasal endoscopy. Treatment options range from medical management (nasal steroid sprays, antihistamines) to surgical procedures such as septoplasty or turbinate reduction.

Key Takeaways

• Definition: Difficulty breathing through one or both nostrils, constant or intermittent.
• Common causes: Deviated nasal septum, enlarged turbinates, nasal polyps, allergies.
• Diagnosis: Nasal endoscopy (small camera through the nostril) identifies the cause.
• Treatment ladder: Medical management first (sprays, antihistamines). Surgery only if medical therapy fails.
• When to see an ENT doctor: Persistent obstruction despite 4-8 weeks of medical treatment, or if obstruction affects sleep or quality of life.

What Is Nasal Obstruction?

Nasal obstruction is the sensation of difficulty breathing through one or both nostrils. It may be:

• Constant (always present) or intermittent (comes and goes)
• Unilateral (one side only) or bilateral (both sides)
• Positional (worse when lying down)

Nasal obstruction is not a disease itself but a symptom of an underlying condition affecting the nasal passages. The obstruction may result from structural problems (blockage) or inflammatory problems (swelling of the nasal lining).

Unlike a simple “stuffy nose” from a cold (which resolves in 7-10 days), chronic nasal obstruction persists for weeks or months and may require medical or surgical treatment.

Common Causes of Nasal Obstruction

Structural Causes (Physical Blockage)

Inflammatory Causes (Swelling)

Other Causes

• Pregnancy rhinitis (hormonal changes, resolves after delivery)
• Nasal tumors (rare, but require prompt evaluation)
• Foreign body (common in children)
• Trauma (nasal fracture from injury)

For more information on allergic rhinitis, visit the Australian Society of Clinical Immunology and Allergy (ASCIA).

Symptoms of Nasal Obstruction

Patients with nasal obstruction typically experience one or more of the following:

Primary Symptoms

• Difficulty breathing through one or both nostrils
• Mouth breathing (especially during sleep)
• Snoring or sleep apnoea
• Nasal congestion (feeling of fullness or blockage)

Secondary Symptoms

• Dry mouth (from breathing through the mouth)
• Sore throat (especially in the morning)
• Poor sleep quality or daytime fatigue
• Reduced sense of smell
• Frequent nosebleeds (from dry nasal passages)
• Post-nasal drip

Impact on Quality of Life

Chronic nasal obstruction can affect:

• Sleep (fragmented sleep, snoring, sleep apnoea)
• Exercise tolerance (difficulty breathing during physical activity)
• Concentration (daytime fatigue)
• Voice quality (hyponasal speech)
• Children (may affect facial growth and school performance)

Diagnosis of Nasal Obstruction

An ENT doctor in Sydney will diagnose the cause of nasal obstruction using the following approaches:

1. Medical History Review

The doctor asks about:

• Duration and pattern of obstruction (constant vs. intermittent, unilateral vs. bilateral)
• Triggers (allergens, weather changes, lying down)
• Previous treatments (nasal sprays, antihistamines, decongestants)
• Past medical history (allergies, asthma, previous nasal surgery or trauma)
• Medication use (overuse of decongestant sprays)

2. Nasal Endoscopy

This is the most important diagnostic procedure. The doctor passes a thin, flexible tube with a small camera and light through the nostril. It takes 1-2 minutes and causes mild discomfort but is not painful.

What the doctor looks for:

• Deviated septum (the wall is bent to one side)
• Turbinate enlargement (turbinates filling the nasal passage)
• Nasal polyps (smooth, pale growths)
• Nasal valve collapse (side wall sucks in during breathing)
• Adenoid enlargement (in children, seen through the nose)
• Tumours or foreign bodies (rare)

3. CT Scan (Selected Cases)

A CT scan may be ordered if:

• The cause is not clear on nasal endoscopy
• Chronic sinusitis is also suspected
• Surgery is being planned
• A tumour or complication is suspected

4. Allergy Testing

If allergic rhinitis is suspected, the doctor may recommend:

• Skin prick testing (small amounts of allergens placed on the skin)
• Blood tests (specific IgE to common allergens)

For information on CT imaging of the sinuses, visit the Royal Australian and New Zealand College of Radiologists (RANZCR).

Treatment Options for Nasal Obstruction

Treatment follows a stepwise approach – starting with medical management and progressing to surgery only if medical therapy fails.

Medical Management (First-Line Treatment)

Warning: Decongestant nasal sprays (e.g., Otrivin, Sudafed spray) should not be used for more than 3-5 consecutive days. Longer use causes rhinitis medicamentosa (rebound congestion), making the obstruction worse.

Surgical Treatment (When Medical Therapy Fails)

Surgery is recommended when:

• Medical management has failed after 4-8 weeks of optimal treatment
• A structural cause (deviated septum, enlarged turbinates) is identified on nasal endoscopy
• The obstruction significantly affects sleep, exercise, or quality of life

Surgical Procedures for Nasal Obstruction

Important notes about surgery:

• Procedures are performed through the nostrils (no external incisions)
• Usually performed under general anaesthesia
• Most patients return to work within 1 week
• Full improvement in breathing takes 4-6 weeks (after swelling resolves)

Septoplasty: Detailed Information

Septoplasty is the surgical procedure to straighten a deviated nasal septum.

Who needs it:

• Patients with a deviated septum visible on nasal endoscopy
• Nasal obstruction that does not improve with medical therapy
• Recurrent sinus infections related to the deviation
• Frequent nosebleeds from the deviated area

What to expect:

• Performed under general anaesthesia (1-2 hours)
• Surgeon makes a small incision inside the nostril (no external scar)
• The bent cartilage and bone are straightened or removed
• Soft silicone splints may be placed inside the nose (removed at 1 week)

Turbinate Reduction: Detailed Information

Turbinate reduction reduces the size of enlarged inferior turbinates – the bony structures inside the nose covered by soft tissue.

Who needs it:

• Patients with enlarged turbinates visible on nasal endoscopy
• Nasal obstruction not improving with medical therapy
• Often performed together with septoplasty

Techniques:

• Radiofrequency reduction (heat shrinks the tissue)
• Coblation (cold plasma ablation)
• Microdebrider-assisted reduction (removes soft tissue)
• Outfracture (moves the turbinate sideways)

Recovery:

• Usually faster than septoplasty (3-7 days off work)
• Nasal congestion for 2-4 weeks as swelling resolves
• Maximum improvement at 3 months

When to See an ENT Doctor for Nasal Obstruction

You should request a GP referral to an ENT doctor in Sydney if:

• Nasal obstruction persists despite 4-8 weeks of medical therapy (nasal steroid spray + saline rinses)
• You rely on decongestant sprays (Otrivin, etc.) to breathe
• The obstruction affects your sleep (snoring, waking up tired, apnoea)
• You have unilateral obstruction (one side only) – especially if persistent
• You have associated symptoms (facial pain, reduced smell, nosebleeds)
• Children with mouth breathing, snoring, or poor school performance

Living with Nasal Obstruction: Self-Management Tips

In addition to medical treatment, patients can reduce symptoms by:

• Using saline rinses daily (NeilMed or FLO bottles)
• Humidifying bedroom air (especially in winter or air-conditioned rooms)
• Sleeping with head elevated (extra pillow)
• Avoiding triggers (dust mites, pollen, pet dander, smoke)
• Using nasal steroid sprays correctly (aim toward the side wall, not the septum)
• Treating allergies (antihistamines, allergy immunotherapy)

Red Flags: When to Seek Urgent Medical Care

Seek immediate medical attention (emergency department or call 000) if you experience:

• Sudden onset of unilateral nasal obstruction with facial swelling or eye symptoms
• Nasal obstruction after facial trauma (possible nasal fracture)
• Bloody nasal discharge with persistent obstruction (especially unilateral)
• Associated double vision, vision changes, or severe headache

These symptoms may indicate a nasal tumour, nasal fracture, or infection spreading to surrounding tissues.

Frequently Asked Questions (FAQs)

General FAQs

1. What is the most common cause of nasal obstruction?
   The most common causes are deviated nasal septum (structural) and allergic rhinitis (inflammatory). Many patients have both.
2. Can nasal obstruction be caused by allergies?
   Yes. Allergic rhinitis causes swelling of the nasal lining, leading to obstruction. Treating allergies often improves breathing.
3. Is nasal obstruction dangerous?
   Rarely. Chronic nasal obstruction affects quality of life (sleep, exercise, concentration) but is not usually dangerous. However, unilateral persistent obstruction in adults should always be evaluated to exclude a tumour.
4. Can nasal obstruction go away on its own?
   It depends on the cause. Obstruction from a cold resolves in 7-10 days. Obstruction from a deviated septum or enlarged turbinates does not resolve without treatment.
5. How do ENT doctors diagnose the cause of nasal obstruction?
   Using nasal endoscopy – a small camera passed through the nostril to directly visualise the septum, turbinates, and nasal passages.

Treatment FAQs

6. Can nasal obstruction be treated without surgery?
   Yes. Medical management (nasal steroid sprays, saline rinses, antihistamines) is the first-line treatment. Surgery is only recommended if medical therapy fails.
7. How long does it take for nasal steroid sprays to work?
   Nasal steroid sprays take 4-8 weeks of daily use to reach maximum effectiveness. Many patients stop too early.
8. Is septoplasty painful?
   The surgery is performed under general anaesthesia (no pain during). Mild to moderate discomfort during the first week of recovery is normal and managed with pain relief medication.
9. What is the success rate of septoplasty?
   Studies show 80-90% of patients experience significant improvement in nasal breathing after septoplasty.
10. Can a deviated septum get worse over time?
    Not usually. The deviation is stable. However, aging changes or trauma may worsen symptoms.

Recovery FAQs

11. How long is recovery after nasal surgery?
    Most patients return to non-physical work within 1 week. Full healing and maximum breathing improvement takes 4-6 weeks.
12. Will I have nasal packing after surgery?
    Some surgeons use soft silicone splints (removed at 1 week). Traditional nasal packing (gauze) is less common now.
13. Can I fly after nasal surgery?
    Avoid flying for 2-4 weeks after surgery (air pressure changes can cause bleeding or pain).
14. Will septoplasty change the shape of my nose?
    No. Septoplasty straightens the inside of the nose. It does not change the external appearance unless combined with rhinoplasty (cosmetic nose surgery).
15. Can children have septoplasty?
    Septoplasty is usually delayed until facial growth is complete (around age 16-18 for girls, 18-20 for boys) unless the obstruction is severe.

Lifestyle FAQs

16. Does nasal obstruction cause snoring?
    Yes. Nasal obstruction is a common cause of snoring and may contribute to sleep apnoea.
17. Can exercise help nasal obstruction?
    Exercise temporarily constricts blood vessels in the nose, which may improve breathing during and shortly after activity.
18. Does nasal obstruction affect sense of smell?
    Yes. Chronic nasal obstruction reduces airflow to the olfactory nerves, leading to reduced sense of smell (hyposmia).
19. Is nasal obstruction linked to sleep apnoea?
    Yes. Nasal obstruction increases the risk of snoring and obstructive sleep apnoea. Treating the obstruction may improve sleep apnoea symptoms.
20. Can pregnancy cause nasal obstruction?
    Yes. Pregnancy rhinitis (hormonal swelling of the nasal lining) affects up to 30% of pregnant women. It resolves after delivery.

Summary

Nasal obstruction is difficulty breathing through one or both nostrils. Common causes include deviated nasal septum, enlarged turbinates, nasal polyps, and allergic rhinitis. ENT doctors diagnose the cause using nasal endoscopy.

Treatment begins with medical management (nasal steroid sprays, saline rinses, antihistamines) and may progress to surgical procedures such as septoplasty or turbinate reduction for patients who do not improve with medical therapy alone.
