Paediatric Tonsillectomy
When parents bring a child to see me about their tonsils, it is usually because there is a clear ongoing problem such as disturbed sleep, noisy breathing, recurrent tonsillitis, difficulty eating, or repeated infections that are affecting family life. A paediatric tonsillectomy is an operation to remove tonsil tissue, most commonly to treat sleep-disordered breathing caused by enlarged tonsils, or recurrent tonsillitis.
I have performed nearly 1000 tonsillectomies, and an important part of my role is helping families decide whether surgery is needed at all and, if it is, which type of operation is most appropriate. In some children, enlarged adenoids or middle ear problems are also part of the picture, and surgery may sometimes need to be combined with an adenoidectomy and/or grommet insertion, depending on the child’s symptoms and findings. If surgery is needed, the right procedure will always be chosen on an individual basis.
In my practice, most paediatric tonsillectomies are performed using intracapsular coblation tonsillectomy. This removes the bulk of the tonsil while leaving a very thin layer of tissue over the throat muscles underneath. For most children, this means less pain, an easier recovery, and, importantly, a lower risk of bleeding than with a traditional extracapsular tonsillectomy.
This lower bleeding rate is particularly important in children because they have a small circulating blood volume, so even a relatively small bleed can be clinically significant.
Why might a child need a tonsillectomy?
The commonest reasons include:
enlarged tonsils causing snoring, restless sleep, pauses in breathing, or obstructive sleep apnoea
recurrent tonsillitis
difficulty swallowing because the tonsils are very large
repeated infections affecting school attendance, sleep, or quality of life
recurrent quinsy, although this is less common in children than in adults
For many children, the main issue is not infection but obstruction — large tonsils narrowing the airway, especially during sleep. In these cases, surgery is often aimed at improving breathing, sleep quality, daytime energy, and sometimes eating.
What are the benefits of surgery?
For the right child, tonsil surgery can make a major difference. Depending on the reason for surgery, the benefits may include:
quieter breathing at night
less snoring
improved sleep quality
fewer obstructive episodes or pauses in breathing
easier swallowing
fewer throat infections
improved daytime energy, concentration, and general wellbeing
How is the operation usually done?
Most children I treat have an intracapsular coblation tonsillectomy rather than a traditional extracapsular tonsillectomy.
With intracapsular coblation, most of the tonsil is removed but a very thin layer is left over the muscle underneath. Coblation uses controlled radiofrequency energy to remove tissue at lower temperatures than standard diathermy.
The main advantages are:
less pain after surgery
easier swallowing during recovery
a lower risk of bleeding
a lower chance of needing to come back into hospital because of bleeding or pain
Published studies suggest that the risk of bleeding after intracapsular tonsillectomy is significantly lower than after traditional extracapsular tonsillectomy, with some reports quoting a reduction of around tenfold.
That said, a traditional bipolar tonsillectomy is still sometimes the more appropriate operation. This removes the tonsil completely and may be preferred in certain situations depending on the child’s age, anatomy, symptoms, and the reason for surgery. The most appropriate procedure will always be discussed carefully before surgery so that the treatment plan is tailored to the individual child.
Will the tonsils grow back?
After intracapsular surgery, a small amount of tonsil tissue is intentionally left behind, so there is a small possibility of regrowth. This is more likely in very young children, particularly those under 3, but it remains uncommon. In the vast majority of cases, revision surgery is not needed.
This is one of the main trade-offs of intracapsular surgery: it offers a lower risk of bleeding and an easier recovery, but with a small chance of future regrowth because a thin layer of tonsil tissue is deliberately left behind.
Why is the lower bleeding risk so important in children?
This is an important point. Children have a smaller blood volume than adults, so post-operative bleeding must always be taken seriously. One of the major advantages of intracapsular coblation in children is that it significantly reduces this risk.
For parents, that usually means not only a safer recovery, but also a better chance of avoiding readmission to hospital.
Are there any downsides to intracapsular surgery?
Yes — and it is important to explain this clearly.
Because intracapsular surgery leaves behind a very small rim of tonsil tissue, there is a small risk of regrowth over time. In most children this does not cause a problem, and revision surgery is very rarely needed, but the risk of regrowth is higher in very young children, particularly those under the age of 3.
The usual trade-off is:
intracapsular coblation: lower pain, lower bleeding risk, easier recovery, but a small chance of regrowth
traditional bipolar tonsillectomy: removes all tonsil tissue, but with a higher risk of bleeding and a tougher recovery
For most children, especially where the main issue is airway obstruction or sleep-disordered breathing, intracapsular coblation is an excellent option. However, it is not the right operation for every child, and the most appropriate procedure will always be discussed on an individual basis.
Does removing the tonsils affect the immune system long term?
This is a common concern for parents. The tonsils do form part of the immune system, particularly in early childhood, but they are only one small part of a much wider network of lymphoid tissue throughout the body.
In practical terms, there is no good evidence that children who have their tonsils removed become generally more prone to everyday infections in the long term. The immune system continues to function well without them, and for children whose tonsils are causing repeated infection or airway obstruction, the overall benefit of surgery can outweigh the fact that the tonsils themselves are removed.
What are the main risks of paediatric tonsillectomy?
Although paediatric tonsillectomy is a very common operation, it is still a procedure under general anaesthetic and does carry risks.
The main risks include:
bleeding
infection
pain
dehydration if drinking is poor after surgery
sickness after the anaesthetic
temporary bad breath
rare injury to the lips, teeth, tongue or gums from the instruments used during surgery
a small risk of tonsil tissue regrowth after intracapsular surgery
very rarely, the need for revision surgery later on
With traditional tonsil surgery, post-operative bleeding is more common. With intracapsular surgery, the bleeding risk is substantially lower, which is one of the main reasons it has become such an important technique in paediatric practice.
Aftercare
Most children go home the same day, although some stay overnight depending on age, breathing, underlying medical conditions, or how they recover after the anaesthetic.
Pain relief
Even with intracapsular surgery, some throat pain is expected. The pain is usually less severe than with traditional tonsillectomy, but regular pain relief is still important for the first few days. Some children also complain of ear pain, which is usually referred pain from the throat.
Eating and drinking
Drinking well is very important after surgery. Children should be encouraged to drink little and often, and to return to eating as normally as possible as soon as they feel able. Swallowing helps recovery, and eating and drinking normally can also help keep the throat clean.
Recovery
Recovery after intracapsular tonsillectomy is usually faster and easier than after traditional tonsil surgery, but children still need time at home. As a guide, it is sensible to plan for around 10 to 14 days off school or nursery.
When should I seek urgent help?
Urgent assessment is advisable if your child has:
any fresh bleeding from the mouth or nose
repeated vomiting of blood
difficulty breathing
signs of dehydration
pain that is not controlled despite medication
increasing drowsiness or a child who looks significantly unwell
Any fresh bleeding after tonsil surgery should always be taken seriously.
