"Collapsed nose" means two quite different things, and sorting out which one you are describing is the first thing I do.
Nasal valve collapse is a functional problem. The sidewall of your nose draws inwards when you breathe in, closing the airway. From the outside your nose usually looks entirely normal. It is common, frequently missed, and very treatable.
Saddle nose deformity is a structural collapse of the bridge itself, so the middle of the nose sinks. This one is visible, much less common, and always has an underlying cause that needs identifying before anyone operates.
Most people who search for "collapsed nose" have the first. This covers both.
Where is the nasal valve, and why does it matter?
The narrowest part of your entire airway is not deep inside your nose. It is about a centimetre in, at what we call the internal nasal valve: the angle between the septum in the middle and the upper lateral cartilage forming the sidewall. In most people that angle is somewhere between ten and fifteen degrees, and it is where the greatest resistance to airflow sits.
There is a second, more external one at the nostril rim, held open by the lower lateral cartilages. That is the external nasal valve.
Because the valve is the narrowest point, a small loss of support there costs you far more airflow than the same loss further back. Airflow through a tube falls steeply as the radius narrows, which is why a millimetre at the valve matters more than several millimetres deeper in the nose. It is also why people with valve problems describe a very specific pattern: fine at rest, hopeless under exertion. The harder you breathe in, the more negative the pressure inside the nose, and the more a weak sidewall gets sucked shut.
What does nasal valve collapse feel like?
- Breathing that gets worse the harder you try, particularly during exercise
- A sense that the nostril itself is closing rather than something being blocked deep inside
- Sprays and antihistamines making little or no difference
- Nasal strips producing an obvious improvement
- Often worse on one side, and often after previous nose surgery or an injury
That last point is important and I will come back to it.
Is it nasal valve collapse or a deviated septum?
These two are confused constantly, sometimes by doctors, and the distinction decides which operation you need. A deviated septum is a bend in the wall that divides the two sides of the nose: a fixed obstruction, there every time you breathe. Valve collapse is a failure of sidewall support: a dynamic obstruction that gets worse the harder you breathe in. A deviated septum blocks the nose fairly constantly, and usually more on one side, because the obstruction is a fixed bend in cartilage and bone.
| Deviated septum | Nasal valve collapse | |
|---|---|---|
| What has failed | The dividing wall is bent | The sidewall has lost its support |
| Pattern of blockage | Fairly constant, usually one side worse | Worse the harder you breathe in |
| Changes as you breathe | No | Yes, the sidewall draws inwards |
| Cheek pull test | Little change | Often a clear improvement |
| Helped by decongestant sprays | Not really | No |
| The operation | Septoplasty | Grafts to rebuild the sidewall |
The spray question is worth a sentence, because it is a useful clue in its own right. Decongestant sprays shrink the swollen lining of the nose; they do nothing for bent cartilage or a sidewall that has lost its support. If sprays transform your breathing, the problem is mostly lining, usually the turbinates. If they achieve nothing, think structure: septum, valve, or both.
And it is very often both. The septum forms one wall of the internal valve, so a bend low down near the valve narrows the angle further, and correcting one problem while ignoring the other produces a partial result. This is precisely the group of patients who had a technically successful septoplasty and are mystified that their breathing barely changed. The septum is now straight. The valve was never touched.
The self-test worth doing
The cheek pull, or Cottle manoeuvre. Place a fingertip on your cheek beside your nose and draw the skin gently outwards and slightly upwards, then breathe in through that nostril. If breathing suddenly becomes much easier, that is a positive result and points to the internal valve. The cheek pull makes little difference to a blockage caused purely by a deviated septum, which is part of what makes it useful.
The modified version. Use a cotton bud or the blunt end of a small instrument to support the sidewall from inside the nostril, without distorting the nostril rim, then breathe in. This is more specific, because the cheek pull can give a false positive by dragging on other tissue.
The nasal strip test. Wear a strip across the bridge for a few nights. A clear improvement is meaningful information.
None of these replaces an examination, but they are genuinely useful. If a strip transforms your breathing, tell your surgeon: it changes the operation you need. Septoplasty alone will not fix valve collapse, and this is one of the commonest reasons people report that nasal surgery "only half worked".
What causes nasal valve collapse?
Previous rhinoplasty. This is one of the best-recognised causes. A nose reduced too aggressively, particularly where the upper lateral cartilages were separated from the septum and not reconstructed, loses its sidewall support. It can appear years later as the tissues gradually settle. This is not a criticism of anyone: it reflects surgical fashions of earlier decades, when reduction was the goal and structural support was less well understood.
Previous septal surgery occasionally contributes too. Removing septal cartilage without preserving its supporting framework can weaken the nose, which is one reason breathing sometimes fails to improve, or even worsens, after septoplasty alone.
Ageing. Cartilage weakens and the tip loses projection over time, narrowing the valve angle. A slow, symmetrical version of the same problem.
Trauma. Fractures that heal with the sidewall pushed in, or that damage the cartilage framework.
Naturally weak or thin cartilage, sometimes with narrow nostrils and a slim nose. Some people simply start with less support.
[Septal perforation](/blog/septal-perforation), which destabilises the middle of the nose and can progress to bridge collapse.
For saddle nose specifically, the causes are more serious and need excluding properly: an untreated septal haematoma in childhood, granulomatosis with polyangiitis and other vasculitides, cocaine use, and rarely infection or malignancy. Anyone with a collapsing bridge needs blood tests and often a biopsy before surgery is discussed, because operating on active inflammatory disease fails. I would rather delay an operation by three months than rebuild a nose that is still being destroyed from within.
What does a collapsed nose look like?
Nasal valve collapse frequently looks like nothing at all at rest. The diagnostic sign is dynamic: ask the person to breathe in briskly and watch the sidewall get drawn inwards. Sometimes there is a visible hollowing just above the nostril crease, or a pinched appearance to the middle third of the nose in someone who has had previous surgery.
Saddle nose is obvious in profile, with a scooped-out bridge, and often with an upturned tip and shortened nose.
So yes, a nose can look completely straight from the outside and still be badly blocked on the inside. A straight nose rules out neither a deviated septum nor valve collapse, and judging the airway by the mirror is a mistake patients and doctors both make.
How is nasal valve collapse diagnosed?
This is one of the conditions most often missed, because a standard examination looks at the septum and the turbinates and stops there. Diagnosis depends on watching the nose dynamically while the patient breathes in, and on testing whether supporting the wall of the nose relieves the blockage. Any ENT surgeon or facial plastic specialist assessing nasal blockage should be doing this routinely: a dynamic assessment of the sidewall on brisk inspiration, a Cottle or modified Cottle test, and an examination of the septum and turbinates alongside, not instead.
A scan does not make this diagnosis. CT shows sinuses and the bony skeleton well, but valve collapse is a problem of movement, and movement does not show on a static image. The examination has to be live.
Patients frequently arrive having had a previous operation that corrected a deviated septum properly and left the valve untouched, which is why their symptoms never improved. Where the nasal airway is narrowed at the valve, treatment aimed at the septum alone will not work. Because the condition sits between ear, nose and throat surgery and facial plastics, it helps to be assessed by someone who works in both, and specialists differ a great deal in how routinely they look for it. If your medical care so far has focused on sinus treatment, it is worth booking an appointment specifically to have the valve examined.
How is nasal valve collapse repaired?
The principle is straightforward: valve collapse is a structural failure, so the repair is structural. You cannot medicate a sidewall back into place, and no amount of spray will help.
Before anyone reaches for a scalpel, nasal strips and internal dilators are worth trying. They are cheap, reversible, and diagnostic in their own right: if they help, that supports the diagnosis. Some people, particularly those whose only symptom is night-time congestion, settle for a strip indefinitely and never need more. They are supports rather than treatment, though. Surgery is the definitive correction, and the choice of technique depends on which part has failed.
Spreader grafts are the workhorse. Thin strips of cartilage placed between the septum and the upper lateral cartilage on each side, widening the internal valve angle and holding it open. They also help straighten a deviated middle third, which is why they feature in so many functional and revision rhinoplasty operations.
Alar batten grafts support the sidewall further out, for external valve collapse or a segment that visibly caves in.
Lateral crural strut grafts reinforce or reposition the lower lateral cartilages, useful where the nostril rim itself is weak or malpositioned.
Septal extension and columellar strut grafts restore tip support, which indirectly opens the valve.
The cartilage usually comes from your own septum. If the septum has already been harvested at a previous operation, which is often the case in revision work, then ear cartilage or rib cartilage is used instead. Ear works well for curved grafts; rib provides the strongest and most plentiful material and is what saddle nose reconstruction generally requires. Bone is not normally used for this.
These are done through a septorhinoplasty approach, because the work is on the structural framework rather than just the septum. In practice most people having valve surgery also have a septal deviation and an enlarged turbinate addressed at the same time, since leaving either behind produces a partial result.
What it does for quality of life
The improvement people report is usually about exercise, sleep, and the constant low-level effort of breathing through a nose that does not work. Blockage that only appears under exertion sounds minor written down. It is not minor if you run, or if it wakes you at night.
Correcting it will not change how your nose looks in any way most people notice, and it is one of the more satisfying operations to do, because the symptom is specific and the fix is mechanical.
What does nasal valve surgery cost in the UK?
Valve reconstruction is not a standalone procedure in my practice: it forms part of a functional septorhinoplasty. My septorhinoplasty fees start from £10,500, and revision cases, which is what most valve collapse after previous surgery amounts to, start from £12,000. Rib grafting adds complexity and time and is quoted individually.
Consultation is £250. Full detail is on my pricing page, and I quote in writing before anyone commits to anything.
Whether insurance covers it depends entirely on the documented indication and on your policy. Functional nasal surgery for genuine obstruction is often covered. Anything with a cosmetic component usually is not, and I will not describe a cosmetic operation as a functional one to get it funded.
Frequently asked questions
Can I have a deviated septum and nasal valve collapse at the same time?
Yes, and it is common. The septum forms one wall of the internal valve, so a bend near the valve narrows it further. This is why I examine both in everyone with nasal blockage, and why fixing only one so often gives a partial result.
Why do nasal sprays not help nasal valve collapse?
Sprays shrink the swollen lining of the nose. Valve collapse is a mechanical failure of cartilage support, so there is no swelling for a spray to act on. Sprays achieving nothing is itself a pointer towards a structural cause.
Can nasal valve collapse be fixed without surgery?
Not corrected, no. Nasal strips and internal dilators can help symptomatically and are worth trying, but they are supports rather than treatment.
Will a septoplasty fix my valve collapse?
No. Septoplasty straightens the septum in the middle. Valve collapse is a failure of sidewall support and needs grafting. Confusing the two is a common cause of disappointing results.
Can a nose collapse after rhinoplasty?
Yes. It is one of the best-recognised causes. Over-reduction without structural reconstruction can produce valve collapse months or years afterwards.
Is a collapsed nose an emergency?
Valve collapse is not. A rapidly collapsing bridge, particularly with crusting, bleeding or systemic symptoms, needs prompt assessment to exclude vasculitis or infection.
Does cocaine cause nasal collapse?
It can. It damages the blood supply to the septum, causing perforation and then loss of bridge support. It must be fully stopped before reconstruction, or the repair will fail.
How long is recovery from valve surgery?
Similar to septorhinoplasty: about two weeks before you are presentable, six weeks before strenuous exercise, and up to a year for the final refinement.
Will my nose look different afterwards?
Usually slightly. Spreader grafts widen the middle third a little, which most people do not notice, and some find their nose looks straighter. I discuss this specifically before surgery.
Is this covered by the NHS?
Sometimes, for clear functional obstruction, though thresholds vary by area and waits are long. Valve reconstruction with grafting is less widely available than straightforward septoplasty.
If your breathing collapses under exertion, or a nasal strip transforms it, that is worth having properly examined rather than treated as ordinary congestion. You can book a consultation and I will assess the valve dynamically, not just look at your septum.
