Nasal Valve Collapse: The Most Common Cause of a Blocked Nose You’ve Never Heard Of

Many patients come to clinic saying:
“My nose feels blocked but sprays don’t work.”
“I had septoplasty but I still can’t breathe properly.”
“I can breathe better if I pull my cheek sideways.”
“One side collapses when I breathe in.”
In a large number of these patients, the problem is nasal valve collapse — one of the most common, and most commonly missed, causes of nasal obstruction.
As a Consultant ENT & Rhinology Surgeon in Hampshire, I see this problem frequently, particularly in patients who have persistent blockage despite using nasal sprays or even after previous septoplasty.
What Is the Nasal Valve?
The nasal valve is the narrowest part of the nasal airway. It is located in the middle part of the nose and is supported by cartilage.
Because it is already the narrowest point, even a small weakness or narrowing here can significantly reduce airflow.
You can think of it like a doorway — if the doorway becomes narrower or the frame becomes weak, airflow is restricted even if the rest of the corridor is wide.
What Is Nasal Valve Collapse?
Nasal valve collapse occurs when the side of the nose falls inward breathing in, narrowing the airway and making breathing difficult.
It may be:
Structural (cartilage weakness)
Post-traumatic (after a broken nose)
After previous rhinoplasty
Associated with a deviated septum
Present naturally due to narrow anatomy
Common Symptoms of Nasal Valve Collapse
Typical symptoms include:
One side of the nose feels blocked
Blockage worse when breathing in deeply
Blockage worse during exercise
Blockage worse at night
Nose feels better if you pull your cheek sideways
Breathe Right strips help
Septoplasty didn’t fix the problem
Nose looks like it pinches inward when you breathe in
That last sign — visible collapse on inspiration — is a major clue.
Why Nasal Sprays Don’t Work
This is very important.
Nasal sprays treat inflammation.Nasal valve collapse is a structural problem.
Sprays cannot:
Strengthen cartilage
Widen the nasal valve
Stop the sidewall collapsing
This is why many patients say:
“I’ve tried sprays for months and nothing changes.”
If you’ve used a steroid spray properly for 3 months and still can’t breathe well, the cause may be structural.
Why Septoplasty Sometimes Doesn’t Fix a Blocked Nose
Septoplasty straightens the septum.But breathing depends on three main areas:
Septum
Turbinates
Nasal valve
If the valve is weak or narrow, septoplasty alone may not fix the problem.
This is why some patients say:
“I had septoplasty but I still can’t breathe.”
In these cases, the correct operation is often functional septorhinoplasty, which strengthens and widens the nasal valve.
How Is Nasal Valve Collapse Fixed?
Treatment depends on severity but may include:
Cartilage grafts to support the valve
Spreader grafts
Alar batten grafts
Rim grafts
Structural septorhinoplasty
The aim is to support and widen the airway, not just straighten the septum.
When done properly, this can significantly improve breathing.
Simple Test: The Cheek Pull Test
Try this:
Pull your cheek sideways while breathing in through your nose.
If breathing improves significantly, this strongly suggests nasal valve collapse.
This is not a perfect test, but it is a very common sign.
When to Seek Specialist Assessment
You should consider specialist assessment if:
One side of your nose is always blocked
You breathe better pulling your cheek sideways
Breathe Right strips help
Septoplasty didn’t fix the problem
Your nose collapses when you breathe in
Sprays don’t work
Assessment is available with Mr Tim Biggs, Consultant ENT & Rhinology Surgeon specialising in nasal obstruction and functional septorhinoplasty.
Consultations take place at Adnova Clinic, with patients attending from Portsmouth, Southampton, Winchester and across Hampshire.
Final Thoughts
Nasal valve collapse is one of the most common causes of persistent nasal blockage — and one of the most commonly missed.
Many patients are treated for years with sprays when the real problem is structural.
Once correctly diagnosed and treated, breathing improvement can be significant and long-lasting.

Nasal Valve Collapse – Frequently Asked Questions (FAQ)
What is nasal valve collapse?
Nasal valve collapse occurs when the narrowest part of the nasal airway becomes weak or narrow and falls inward during breathing, reducing airflow.It is one of the most common structural causes of a blocked nose, particularly in patients whose symptoms do not improve with nasal sprays or septoplasty alone.
What are the symptoms of nasal valve collapse?
Common symptoms include:
One side of the nose feels blocked
Blockage worse when breathing in deeply
Breathing worse during exercise
Breathing worse at night
Breathing improves when pulling the cheek sideways
Breathe Right strips help
Septoplasty did not fix the problem
The nose looks like it collapses inward when breathing in
Visible collapse on inspiration is a particularly important sign.
Why don’t nasal sprays work for nasal valve collapse?
Nasal sprays treat inflammation inside the nose.Nasal valve collapse is a structural problem, meaning sprays cannot:
Strengthen cartilage
Widen the airway
Stop the nasal sidewall collapsing
If you have used a steroid nasal spray correctly for at least 3 months and still cannot breathe properly, a structural cause such as nasal valve collapse should be considered.
Why am I still blocked after septoplasty?
Septoplasty straightens the septum, but breathing depends on three main areas:
Septum
Turbinates
Nasal valve
If the nasal valve is weak or narrow, septoplasty alone may not fix the problem.In these cases, a functional septorhinoplasty is often required to strengthen and widen the nasal valve.
How is nasal valve collapse treated?
Treatment usually involves structural support of the nasal valve, which may include:
Spreader grafts
Alar batten grafts
Rim grafts
Septoplasty (if needed)
Functional septorhinoplasty
The aim is to support and widen the airway, not just straighten the septum.
What is the cheek pull test for nasal valve collapse?
A simple test is:
Pull your cheek sideways while breathing in through your nose.
If breathing improves significantly, this suggests nasal valve collapse.This is sometimes called the Cottle manoeuvre and is a common clinical sign.
Can nasal valve collapse happen after rhinoplasty?
Yes. Nasal valve collapse can occur after rhinoplasty if:
Too much cartilage is removed
Structural support is weakened
The nose is over-narrowed
This is a common reason for breathing problems after cosmetic rhinoplasty.
When should I see a specialist about nasal valve collapse?
You should consider specialist assessment if:
One side of your nose is always blocked
You breathe better pulling your cheek sideways
Breathe Right strips help
Septoplasty didn’t fix the problem
Your nose collapses when you breathe in
Nasal sprays don’t work
Who treats nasal valve collapse in Hampshire?
Assessment and treatment for nasal valve collapse are provided by Mr Tim Biggs, Consultant ENT & Rhinology Surgeon.Consultations take place at Adnova Clinic, with patients attending from Portsmouth, Southampton, Winchester and across Hampshire.
Key Takeaway
Nasal valve collapse is one of the most common causes of persistent nasal blockage — especially when sprays and septoplasty haven’t worked.Once correctly diagnosed and treated with structural support, breathing improvement can be significant and long-lasting.
