Why Does My Child's Nose Whistle When Breathing? Could There Be a Hole in the Nasal Septum?
Your child is sitting quietly, reading or watching television.
Suddenly, you notice a faint whistling sound.
At first, you assume they are making the noise deliberately.
But then you realise something unusual.
The sound seems to come from their nose whenever they breathe.
It may be more noticeable when they breathe deeply.
Sometimes the nose also feels dry or crusty.
Occasionally, your child may experience a small nosebleed.
Naturally, parents begin wondering:
“Why is my child's nose whistling?”
“Could something be blocking their nose?”
“Is there a hole inside the nose?”
“Will they need an operation?”
There are several possible explanations.
One relatively uncommon cause is a perforated nasal septum.
Understanding what this means can help parents recognise when a simple nasal examination may be useful.
What is the nasal septum?
The nasal septum is the wall separating the right and left nasal passages.
Its front portion is mainly made of cartilage, while the deeper portion contains bone.
Both sides are covered by a delicate lining called mucosa.
The septum supports the nose's shape and influences how air travels through the nasal passages.
Normally, air passes along each side of the septum.
However, if an opening develops in the septum, airflow may change.
This opening is called a nasal septal perforation.
The ENT UK septal perforation information leaflet explains this condition. EN UK
Why does a septal perforation cause whistling?
When air passes through a small opening in the nasal septum, it may create turbulence.
This disturbed airflow can produce a whistling sound.
The noise may be particularly noticeable when the child breathes deeply or when the nose is relatively clear.
However, not every septal perforation produces whistling.
Some children experience crusting, dryness or bleeding instead.
Others have no noticeable symptoms.
A whistling nose does not automatically mean that a hole is present.
Dried mucus, temporary narrowing of a nasal passage, and other airflow changes can also produce unusual nasal sounds.
A clinical examination is needed to establish the cause.
What causes a nasal septal perforation in children?
Several factors may contribute.
Nasal trauma
A significant blow to the nose can injure the septum.
Occasionally, blood collects beneath the septal cartilage lining.
This is called a septal haematoma.
If it is not recognised and treated promptly, the cartilage may become damaged.
This can occasionally lead to a septal perforation.
Repeated nasal injury
Repeated rubbing, scratching or picking inside the nose can damage the delicate lining.
However, parents should not assume that ordinary occasional nose picking has caused a perforation.
Previous nasal procedures
A septal perforation may occasionally develop after surgery or another procedure involving the nasal septum.
This is an uncommon complication.
Foreign bodies
An object lodged inside the nose can cause local irritation and tissue injury.
Button batteries are particularly dangerous because they can rapidly damage nasal tissues.
Inflammatory conditions
Rarely, certain inflammatory or autoimmune diseases can damage the nasal septum.
These explanations are uncommon in children but may require investigation if the history or examination suggests an underlying condition.
A 2025 systematic review involving 219 paediatric patients identified previous procedures and trauma among the leading reported causes. PubMed
What symptoms should parents look for?
A child with a septal perforation may experience several symptoms.
These include nasal whistling, recurrent crusting, dryness, intermittent nosebleeds and a sensation of nasal blockage.
Some children complain that their nose feels uncomfortable even though they can breathe through it.
Others repeatedly remove crusts because the nose feels irritated.
A larger perforation may occasionally affect the nose's structural support.
However, this is not typical of every small perforation.
Symptoms depend partly on the opening's location and size and the condition of the surrounding nasal lining.
Whistling does not reliably indicate the severity of the problem.
Is a whistling nose dangerous?
A persistent nasal whistle is not usually an emergency when the child is otherwise well.
However, the underlying cause matters.
If the noise is associated with repeated bleeding, persistent crusting, pain, or changes in nasal shape, seek medical assessment.
A child who has recently injured their nose requires particular attention.
Increasing nasal blockage and pain following trauma may indicate a septal haematoma rather than an established perforation.
A suspected septal haematoma requires same-day emergency ENT assessment because delayed treatment can damage the septal cartilage.
The NHS Greater Glasgow and Clyde referral guidance specifically identifies suspected septal haematoma as an ENT emergency. Right Decisions
Can nasal sprays cause septal problems?
Some nasal medicines can irritate the nasal lining, particularly when used incorrectly.
For example, repeatedly aiming a nasal spray at the middle wall of the nose may cause irritation or bleeding.
This does not mean that appropriately prescribed steroid nasal sprays are generally unsafe.
They can help children with allergic rhinitis and other inflammatory nasal conditions.
The key points are correct technique, age-appropriate prescribing, and regular review if symptoms persist.
When using a prescribed nasal spray, generally direct the nozzle away from the septum, towards the outer wall of the nasal passage.
The ENT UK nasal-spray technique guide explains this approach.
Parents should not stop prescribed medication without discussing concerns with the treating clinician.
How is a septal perforation diagnosed?
Diagnosis usually begins with a careful examination of the nose.
The clinician will ask when the whistling began and whether there has been previous trauma, surgery, persistent crusting or bleeding.
They may also ask about nasal sprays and other medicines.
The clinician can often examine the front of the nasal cavity using a light and an appropriate nasal examination instrument.
If the diagnosis remains uncertain, a specialist may consider nasal endoscopy.
This involves using a small camera to examine the nasal passages.
In children, the decision depends on age, symptoms, and the child's ability to tolerate the examination.
Do not diagnose a perforation simply because a parent hears a whistling sound.
Will my child need a CT or MRI scan?
Usually not for a straightforward suspected septal perforation.
A direct examination can often establish the diagnosis.
Imaging may occasionally be considered if there are unusual findings, significant trauma, suspected deeper disease or concerns about associated structures.
Blood tests may also be appropriate in selected children when an inflammatory or systemic condition is suspected.
However, extensive investigations are not automatically necessary.
The aim is to identify the cause while avoiding unnecessary procedures.
What can parents do at home?
If your child is otherwise well and the nose feels dry or crusty, gentle supportive care may help while awaiting assessment.
An age-appropriate saline nasal spray may help moisturise the nasal lining.
Encourage your child to avoid repeatedly picking or rubbing inside the nose.
Do not try to remove deeply attached crusts with cotton buds, tweezers, or other objects.
Avoid putting concentrated essential oils or unprescribed chemicals inside the nose.
If the child uses prescribed nasal medication, check the technique with a pharmacist or clinician.
Home care may reduce irritation, but it cannot reliably close an established septal perforation.
Does a septal perforation heal by itself?
A true, established septal perforation generally does not close spontaneously.
However, the symptoms may be manageable without surgery.
Some children have small perforations that cause little difficulty.
Others experience persistent crusting, bleeding or troublesome airflow noise.
Treatment therefore depends on the symptoms, the size and location of the perforation, its cause and the child's stage of nasal growth.
The first priority is usually to protect the remaining nasal lining and address any underlying condition.
Does every child need surgery?
No.
Many children can be managed conservatively.
This may involve appropriate nasal moisturising treatment, avoiding further trauma and monitoring symptoms.
For selected patients with persistent problems, specialists may consider treatment.
Options can include a septal button or surgical repair.
However, these approaches are not suitable for every child.
Surgical decisions are especially important in children because the nose and septum continue to develop as they grow.
The potential benefits must be balanced against operative risks, recurrence and possible effects on nasal development.
What does recent research say about surgery?
A systematic review published online on 12 August 2025 examined nine retrospective studies involving 219 children.
The researchers reported an overall surgical closure rate of approximately 86% across the included literature. PubMed
However, this figure requires careful interpretation.
The studies were retrospective, involved selected patients and used different surgical techniques.
The reported results do not mean that every child has an 86% probability of successful repair.
Long-term outcomes, individual anatomy and the underlying cause remain important.
Do not present surgery as automatically necessary or as a guaranteed permanent solution.
When should parents seek urgent medical help?
Seek same-day urgent assessment if your child has recently injured their nose and develops increasing pain, significant blockage or swelling inside the nasal passages.
A suspected septal haematoma must not be left until a routine outpatient appointment.
Seek urgent medical advice for significant recurrent bleeding, rapidly worsening nasal symptoms, fever with increasing facial pain or swelling, or a child who appears generally unwell.
Go to A&E if a button battery may be lodged inside the nose, even if the child initially appears well.
If your child has a nosebleed, sit them upright, lean them forward, and apply continuous pressure to the soft part of the nose for 10–15 minutes.
Seek emergency assessment if significant bleeding continues despite correct first aid.
Call 999 for severe breathing difficulty, collapse, reduced consciousness or another life-threatening emergency.
The NHS nosebleed guidance provides further first-aid and emergency advice.
When should my child see a paediatric ENT specialist?
Consider assessment if the nasal whistle persists, returns repeatedly, or is associated with crusting, bleeding, or nasal discomfort.
ENT review is also appropriate if a perforation has been identified, symptoms follow previous nasal surgery, or the diagnosis remains uncertain.
For families across London, East London, Romford, Ilford, Redbridge, Woodford, Brentwood and Chelmsford, the priority is establishing whether the sound comes from a simple airflow disturbance or a structural nasal problem.
Mr Gaurav Kumar, Consultant ENT Surgeon, assesses children with persistent nasal symptoms, nasal injuries and other paediatric ENT concerns.
The key message for parents
A whistling noise from your child's nose can be surprising.
Sometimes it is caused by temporary changes in nasal airflow.
Occasionally, it may indicate a perforation of the nasal septum.
The important point is not to assume that every whistle means there is a hole.
Equally, persistent whistling accompanied by crusting, bleeding or nasal discomfort should not simply be ignored.
If your child's nose repeatedly whistles when breathing, arrange an appropriate nasal examination to establish the cause.
This article provides general educational information and does not replace individual medical advice. Children with significant nasal trauma, suspected septal haematoma, uncontrolled bleeding or breathing difficulty require urgent assessment.
FREQUENTLY ASKED QUESTIONS
1. Why does my child's nose whistle when breathing?
A whistling noise can occur when airflow becomes disturbed inside the nose. Possible causes include dried mucus, temporary narrowing and, occasionally, a nasal septal perforation.
2. Does nasal whistling always mean there is a hole in the septum?
No. A whistling sound alone cannot establish the diagnosis. An examination is needed to determine whether a perforation or another cause is present.
3. Can nose picking cause a septal perforation?
Repeated injury to the nasal lining may damage tissue. However, ordinary occasional nose picking does not mean that a child has developed a perforation.
4. Can a septal perforation develop after a broken nose?
Yes, occasionally. Significant trauma or an untreated septal haematoma can damage septal cartilage. Increasing pain or blockage after nasal trauma requires urgent assessment.
5. Can nasal sprays cause a hole in the septum?
Some nasal medications can irritate the septum, especially when used incorrectly. Directing the spray away from the septum helps reduce local irritation. Do not stop prescribed treatment without medical advice.
6. Will a septal perforation heal naturally?
An established perforation generally does not close on its own. However, surgery may not be needed to control symptoms.
7. Does my child need surgery?
Not necessarily. Many children can be managed conservatively. Surgery is considered only when the symptoms, anatomy and individual circumstances justify it.
8. When should nasal whistling be treated as urgent?
Persistent whistling alone is usually not an emergency. Urgent assessment is required when it follows significant nasal trauma with increasing pain or blockage, or when there is uncontrolled bleeding, suspected button battery injury or significant breathing difficulty.
