When patients think about a blocked nose, they usually think of a deviated septum. The septum is important, but it is not the only structure that can narrow the airway. Inside each side of the nose are the turbinates, and when they become enlarged, they can cause stubborn congestion that no amount of straightening the septum will fully fix.
What turbinates do
Turbinates are long, curved ridges of bone covered in soft, blood-rich tissue that run along the side walls of the nose. Most people have three on each side, and the lowest pair, the inferior turbinates, has the biggest effect on airflow.
They are not a design flaw. Turbinates warm, humidify, and filter the air you breathe before it reaches your lungs. They also swell and shrink naturally throughout the day, alternating between the left and right sides in what is called the nasal cycle. This is why one nostril often feels more blocked than the other, especially when lying down.
Why turbinates become enlarged
Allergies. Ongoing allergic rhinitis is a frequent driver of persistent turbinate swelling.
Decongestant spray overuse. Over-the-counter sprays such as oxymetazoline shrink the turbinates quickly, but with continued use the swelling can rebound worse than before. This is called rhinitis medicamentosa, and it has been reported after as little as three days of continuous use. Product labelling generally advises against use beyond a few days.
A deviated septum. When the septum bends to one side, the turbinate on the opposite, more open side often enlarges to fill the space. If the septum is straightened without addressing this turbinate, that side can remain blocked.
Irritants and hormones. Smoke, dry air, and hormonal changes, including pregnancy, can all contribute.
Medical treatment comes first
For many patients, turbinate swelling responds to medical treatment, such as a steroid nasal spray used correctly and consistently, treatment of allergies, and stopping decongestant sprays. I generally recommend a proper trial of these treatments before considering surgery, and I work with patients' family doctors or allergists where appropriate.
When turbinate reduction makes sense
When congestion persists despite good medical treatment, or when the turbinate bone itself is enlarged, surgery can help. Modern turbinate reduction aims to shrink the tissue while preserving its lining and function. Common approaches include:
Reducing the tissue beneath the lining using radiofrequency or a fine powered instrument.
Gently moving the turbinate bone outward to open the airway (outfracture).
Removing a small amount of turbinate bone when the bone itself is the problem.
These procedures are often performed at the same time as septoplasty or rhinoplasty, and recovery is usually folded into the overall healing period.
Why less is more
In the past, some surgeons removed large portions of the turbinates. We now know that excessive removal can lead to a rare but distressing condition called empty nose syndrome, in which the nose feels blocked or uncomfortably dry even though the airway is wide open. A recent review found that mucosa-preserving techniques, such as radiofrequency reduction, produced better functional results with fewer complications than aggressive removal, and that resection should only be performed when clearly justified. My approach is always to reduce, not remove.
Key takeaway
If your nose is chronically blocked, the turbinates may be part of the reason. Many cases improve with the right medical treatment. When surgery is needed, conservative turbinate reduction, often combined with septoplasty or rhinoplasty, can restore comfortable breathing while preserving the functions that make the nose work.
Frequently Asked Questions
Do turbinates grow back after reduction?
The soft tissue can gradually swell again over time, especially if allergies are not controlled. Some patients benefit from a minor repeat treatment years later.
Is turbinate reduction painful?
Most patients describe it as congestion and pressure rather than pain, similar to a heavy head cold, during the early recovery period.
Will turbinate reduction affect my sense of smell?
Conservative reduction targets the lower turbinates, which sit well below the smell-sensing area at the top of the nose. Many patients notice smell improves simply because more air reaches that area.
