What Is Turbinate Reduction?

Turbinate reduction shrinks swollen inferior turbinates that block nasal breathing, usually after sprays have failed. Crusting is common; regrowth can occur.

Short answer

Turbinate reduction is a procedure that shrinks the inferior turbinates, the ridges inside the nose that warm, clean and humidify air, when long-term swelling blocks breathing. It is usually considered only after steroid nasal sprays and other medicines have not helped enough. It can be done with heat-based methods such as radiofrequency, often under local anaesthetic, or by removing tissue beneath the lining. How well it works depends largely on whether the blockage really comes from the turbinates, rather than from a bent septum, allergies or another cause.

Key points

  • Turbinates swell with allergies, rhinitis, infections and some medicines.
  • Saline, steroid sprays, antihistamines and allergy treatment come first.
  • Modern techniques aim to shrink tissue while preserving the nasal lining.
  • Crusting and a blocked feeling are common for a few weeks afterwards.
  • Swelling can return over time, and empty nose syndrome is a rare complication.

What turbinates are and why they swell

Turbinates are bony structures inside the nose covered with mucosa (a moist lining). They filter, warm and humidify air on its way to the lungs. Most airflow passes between the middle and inferior turbinates, so when the inferior turbinates enlarge, breathing through the nose becomes harder.12

The lining can swell briefly with a cold or sinus infection, or stay swollen for long periods, which is called turbinate hypertrophy. Common causes include allergic and non-allergic rhinitis (inflammation of the nasal lining), chronic rhinosinusitis, some medicines and hormonal changes.12

Turbinates are rarely the only issue. A deviated septum (the wall dividing the nostrils), collapse of the nasal valve or the external shape of the nose can also cause blockage, which is why a full assessment of the nose matters before any procedure.1

The nasal airway: septum, turbinates, nostril and nasal valve area, and where septoplasty and turbinate reduction act Two simplified views of the nose, not to scale. Left: a side view of the inside of one nasal passage, facing left, showing its outer side wall. Air enters through the nostril at the front and passes the nasal valve area, the narrowest part of the airway, just in front of the inferior turbinate. Two turbinates project from the side wall: the inferior turbinate, the largest, low on the wall, and the middle turbinate above it. A callout notes that turbinate reduction shrinks inferior turbinate tissue. Right: a view from the front showing the septum, the central wall of cartilage and bone that separates the left and right nasal passages, with an inferior and middle turbinate on the outer wall of each side. A callout notes that septoplasty straightens the septum.

Air enters through the nostril and passes the nasal valve area, the narrowest part of the airway, before flowing past the turbinates on the side wall; the septum divides the left and right passages. Septoplasty straightens the septum, while turbinate reduction shrinks inferior turbinate tissue. Simplified diagram, not to scale.

Treatments tried before surgery

First-line treatment is medical: saline sprays or rinses, antihistamine sprays, steroid sprays and, where relevant, allergy immunotherapy.1 Reduction is usually considered when steroid sprays and antihistamines have not worked.2

Decongestant sprays such as oxymetazoline should only be used briefly. Using them for more than three days can make swelling worse and lead to dependence, so they are not a long-term treatment.1

How turbinate reduction is done

Procedures are done through the nostrils, so there are no external scars, and they aim to shrink the turbinate while keeping its function.13

TechniqueHow it works
Radiofrequency reductionA probe under the lining delivers heat that coagulates tissue and small blood vessels; the turbinate shrinks as it heals4
CoblationLower-temperature heat ablation2
Cauterisation or submucosal diathermyA heated probe reduces blood flow in the tissue23
Microdebrider submucosal resectionTissue is removed through a small opening while the outer lining is kept2
Partial resectionPart of the soft and bony tissue is removed2
Common turbinate reduction techniques.

Radiofrequency reduction is usually done as an outpatient procedure under local anaesthetic.4 Other techniques are often done under general anaesthetic as a day case.2 Turbinate reduction is frequently combined with septoplasty (straightening the septum) when both contribute to blockage.12

There is no single best technique for everyone. The choice depends on the size and type of swelling, the surgeon’s experience and whether other surgery is planned. Comparative evidence between methods is Limited, and the sources reviewed here did not give reliable long-term success rates by technique.

Recovery

Some discomfort is normal for days to weeks, and blood-stained discharge usually settles within a few days. Crusts commonly form and can be softened with nasal drops.3 If a nasal pack is used, it is usually removed the day after surgery.3

People often return to work or school about a day after an in-office procedure, or about a week after one under general anaesthetic. Crusting can last up to three weeks, and full recovery can take up to six weeks.2

Risks and limitations

  • Bleeding: usually a mild ooze, mostly within 8 hours but possible for up to 10 days; significant bleeding is rare.3
  • Crusting and dryness, which can occasionally cause blockage.13
  • Infection, more likely with smoking, obesity or diabetes.3
  • Adhesions, bands of scar tissue inside the nose that can cause blockage and may need dividing.3
  • Change in smell or taste, usually temporary for 2 to 4 weeks and rarely permanent.3
  • Regrowth, with congestion returning over time.12
  • Empty nose syndrome, a rare condition in which the nose feels blocked, dry and crusted despite being too open, usually after extensive removal of turbinate tissue.13

Surgery may not relieve symptoms, particularly when ongoing rhinitis is the main driver.3

When to seek medical advice

After surgery, seek medical advice if the nose becomes increasingly sore and blocked, or if bleeding is more than a mild ooze, as infection and significant bleeding can need treatment.3

Common questions

Is turbinate reduction the same as septoplasty?

No; septoplasty straightens the dividing wall of the nose, while turbinate reduction shrinks the side structures, although the two are often done together.1 See what septoplasty is.

Will I need it again?

Possibly, because turbinate tissue can grow back, although many people are satisfied with the result.2

Can I keep using decongestant spray instead?

Not long term; using it for more than three days can increase swelling and cause dependence.1

Will it help snoring?

It may help when nasal blockage contributes to breathing problems during sleep, which is one recognised reason for the procedure.2 Our page on snoring and sleep apnoea treatments covers the wider options.

Bottom line

Turbinate reduction can help when persistently swollen turbinates block the nose and medicines have not worked. The key questions are whether the turbinates are truly the main cause, and how much tissue can be reduced while keeping the lining that makes the nose work.
