If your child has ongoing nasal blockage, snores at night, breathes through their mouth, makes alarming airway noises or seems to struggle with breathing, you’re not alone – these are very common concerns that we see every day at Melbourne ENT.
As a parent, it’s completely natural to feel worried when your child needs any kind of medical test, particularly one involving a camera. One of the most useful, quick, and gentle ways to assess children’s airways is with a fibre optic endoscopy.
Despite the name sounding technical, this is a simple, safe, and well-tolerated procedure that allows us to clearly understand what’s happening inside your child’s nose and throat – often within seconds.
Dr Simon Braham, our ENT Surgeon, takes a calm, child-focused approach. His goal is always to make the experience as comfortable as possible while providing clear answers for parents.
This page focuses on fibre optic endoscopy in children. For a general overview of the procedure, including how it is performed in adults, see our fibre optic endoscopy page.
What is Fibre Optic Endoscopy for Children?
A fibre optic endoscopy is a procedure that uses a very thin, flexible camera (called a scope) to look inside your child’s:
- Nose
- Nasal passages
- Back of the nose (adenoids)
- Throat
- Voice box (larynx)
The camera is about the width of a piece of spaghetti and has a light source at the tip. It allows us to see detailed structures that we simply cannot assess by looking in the mouth or using a torch.
Importantly, this is:
- Not surgery non-invasive and considered very safe
- No incisions are made
- Usually done while your child is awake
- Completed in under a minute
For most children, it is a brief and manageable experience.
This procedure is also commonly referred to as nasoendoscopy. For more detailed clinical information, see our nasoendoscopy page.
Why Might a Child Need Fibre Optic Endoscopy?
Children are often referred for this test when symptoms are persistent, unclear, or not improving with standard treatment.
Common reasons include:
If your child constantly has a blocked nose, even when they don’t have a cold, this may indicate:
- Enlarged adenoids
- Swollen turbinates
- Structural issues
Snoring in children is not always benign. We may use endoscopy to assess:
- Adenoid size
- Airway narrowing
- Signs of sleep-disordered breathing or sleep apnoea
3. Mouth Breathing
Chronic mouth breathing can affect:
- Sleep quality
- Facial development
- Daytime concentration
- Endoscopy helps identify the underlying cause.
4. Recurrent Infections
For children with frequent:
- Sinus infections
- Nasal discharge
- Ear problems
We can assess whether anatomy or inflammation is contributing.
5. Noisy Breathing (Stridor)
In infants and young children, unusual breathing sounds may relate to:
- Laryngeal structure
- Airway dynamics
This is where endoscopy is particularly valuable.
6. Feeding or Swallowing Concerns (Infants)
In some babies, we assess coordination of breathing and swallowing.
What Does Fibre Optic Endoscopy Show?
This procedure gives us a real-time, dynamic view of your child’s airway.
We can assess:
Adenoids
- Size and degree of blockage
- Whether they are obstructing airflow
Nasal Passages
- Swelling
- Mucus
- Signs of infection or allergy
Nasal Septum
- Whether it is straight or deviated
Turbinates
- Structures that regulate airflow
- Often enlarged in allergies
- Vocal cord movement
- Structural abnormalities
- Signs of irritation or inflammation
Why This Matters
Without endoscopy, we are often making educated guesses.
With it, we can:
- Make an accurate diagnosis
- Avoid unnecessary medications
- Decide whether surgery is appropriate
- Provide reassurance when things are normal
How the Procedure Works
Understanding what actually happens can make a big difference in how comfortable you feel as a parent.
Step 1: Getting Settled
The procedure is done in the consultation room.
- Younger children usually sit on a parent’s lap
- Older children sit upright in a chair
- We take time to explain things in age-appropriate language
Step 2: Preparation
We use a local anaesthetic numbing spray which makes the procedure virtually painless. You should prepare your child and even practice by squirting some saline nasal spray in your child’s nose so they won’t be frightened on the day. Even practice on yourself to show your child it’s really easy. The numbing spray has a strange, almost coconut smell and taste, so I always recommend giving the child their favorite chufa chup or equivalent to disguise the taste. This adds to the fun as they can select it before the appointment.
- Reduce sensitivity
- Open the nasal passages
This is quick and generally well tolerated.
Step 3: The Endoscopy
The scope is:
- Gently inserted into the nostril
- Guided along the natural nasal passage
We carefully move it to view key areas.
The entire process typically takes: 30 to 60 seconds
You may need to help keep your child still, as movement can make the procedure more difficult.
Sitting on a parent’s lap is often best and Dr Braham will show you the best way to assist.
Step 4: Real-Time Viewing
Parents can often see the images on a screen as we explain findings.
Step 5: Immediate Discussion
We talk through:
- What we saw
- What it means
- Next steps (if any)
What Does It Feel Like for a Child?
This is one of the most common questions.
Most children describe it as:
- A tickly sensation
- A strange but brief feeling
- Similar to water going up the nose
Some children may:
- Squirm
- Pull away
- Laugh or react
All of this is completely normal.
Importantly:
- It is not painful
- It is very quick
- The sensation passes almost immediately
Is Fibre Optic Endoscopy Considered Safe?
YES – this is a very safe and routinely performed procedure in paediatric ENT.
Safety Profile:
- No radiation
- No incisions
- No general anaesthetic required
Possible Minor Effects:
- Brief discomfort
- Sneezing
- Watery eyes
These settle quickly.
Rare Issues:
- Mild nosebleed (uncommon and self-limiting)
At Melbourne ENT, we perform this procedure frequently and tailor our approach to each child.
What Parents Worry About Most
“Will it hurt my child?”
No – while it may feel unusual, it is not painful.
“What if my child won’t cooperate?”
This is very common, and we are experienced in managing it calmly.
We:
- Take our time
- Adjust our approach
- Never force a distressed child
“Does my child need sedation?”
In almost all cases: No sedation is required
“Can I stay with my child?”
Absolutely. Your presence is very important and reassuring.
Preparing Your Child: A Brief Overview
Preparation can make a big difference to how smoothly the appointment goes.
Here are general principles (with a more detailed guide in our separate blog):
- Keep explanations simple and calm
- Practice with a saline spray
- Avoid alarming language
- Bring a comfort item
- Bring your child’s favourite lolly
- Stay relaxed – children take cues from you

FAQs about Fibre Optic Endoscopy For Children
How long does fibre optic endoscopy take in a child?
The procedure itself usually takes less than a minute to perform. Most of the appointment is spent making your child comfortable and explaining the findings to you.
Will my child remember it?
Most children move on very quickly and are unaffected afterwards.
Can my child go back to school or daycare?
Yes – immediately.
Is it always necessary?
Only when it adds meaningful diagnostic value.
Why can’t you just look in my child’s throat without a camera?
Many important structures, particularly the adenoids and deeper airway, sit behind the nose and can’t be seen with a light alone. Fibre optic endoscopy allows us to assess these areas clearly and avoid relying on guesswork.
Will my child feel like they can’t breathe during the test?
No – the scope is very thin and does not block the airway. Your child will be able to breathe normally throughout the procedure.
What if my child cries during the procedure?
Crying is quite common and does not prevent us from completing the examination. In some cases, it can even help us observe how the airway functions dynamically.
Can this procedure trigger a nosebleed?
A small nosebleed can occasionally occur, but this is uncommon and usually very minor. We perform the procedure gently to minimise any irritation.
Will my child develop a fear of doctors after this?
Most children tolerate the procedure well when it is handled calmly and confidently. A supportive, child-focused approach helps ensure it does not become a negative experience.
Can I hold my child during the procedure?
Yes – young children are often most comfortable sitting on a parent’s lap. Your presence provides reassurance and helps them remain settled.
Is there a “best age” to have this done?
There is no ideal age, as the procedure can be safely performed from infancy through to adolescence. The approach is simply tailored to suit your child’s age and level of cooperation.
What happens if my child moves suddenly?
We anticipate that children may move and perform the procedure carefully and efficiently. If needed, we can pause and continue once your child is more settled.
Will the camera touch anything sensitive inside the nose?
The scope is guided along the natural nasal passage and avoids sensitive areas as much as possible. While it may feel unusual, it is not harmful.
Can my child eat and drink normally beforehand?
Yes – there are no fasting requirements for this procedure. Your child can eat and drink as usual unless we advise otherwise.
Will I be able to understand what you’re seeing?
We usually show you the images on a screen and explain everything as we go. This helps you clearly understand the findings and any recommended next steps.
Could this test avoid the need for surgery?
In many cases, it can help guide medical treatment or provide reassurance that no intervention is needed. When surgery is recommended, it ensures the decision is based on clear and accurate findings.
Is fibre optic endoscopy painful for children?
Fibre optic endoscopy is not considered painful, although it can feel a little unusual or tickly. Most children tolerate it very well, especially when they are calm and prepared.
How do I know if my child really needs a nasal endoscopy?
This test is recommended when symptoms like snoring, blocked nose, or mouth breathing are ongoing or unclear. It helps us make an accurate diagnosis rather than relying on trial-and-error treatment.
Will my child be traumatised by the experience?
When performed gently and with the right preparation, most children cope very well and recover quickly. Our approach is always calm, patient, and tailored to your child’s comfort level.
Do children need to be restrained for endoscopy?
We use gentle positioning rather than force, often with a child sitting on a parent’s lap. The aim is always to keep your child feeling secure, not distressed.
Can fibre optic endoscopy diagnose adenoids in children?
Yes – this is one of the most accurate ways to assess adenoid size and whether they are causing blockage. It provides a clear answer that cannot be obtained from an external examination.
Is nasal endoscopy safe for toddlers and babies?
Yes, it is safe and commonly performed even in very young children when needed. The technique is simply adjusted to suit their size and level of cooperation.
What if my child has a sensitive gag reflex?
The procedure is performed through the nose rather than the mouth, which helps minimise gagging. Most children tolerate it well for this reason.
Can I stay with my child during fibre optic endoscopy?
Yes, and we strongly encourage it. Your presence helps your child feel safe and significantly improves cooperation.
Will my child need time off school after the procedure?
No recovery time is needed, and your child can return to normal activities straight away. Most children are back to their usual routine immediately.
What conditions can fibre optic endoscopy detect in children?
It can help diagnose enlarged adenoids, nasal obstruction, airway issues, and causes of snoring or noisy breathing. It is also useful for assessing inflammation and structural differences.
Is fibre optic endoscopy better than an X-ray for adenoids?
Yes – it provides a direct, real-time view rather than an indirect image. This makes it more accurate and avoids radiation exposure.
