Recurrent Ear Infections in Children

Recurrent ear infections are very common in childhood and can be exhausting for both children and parents. Some children have repeated episodes of acute middle ear infection, often with fever, earache and disturbed sleep. Others have repeated infections of the ear canal itself. Although most children grow out of this tendency with time, recurrent infections can affect sleep, nursery or school attendance, hearing, and overall family life.

When I assess a child with repeated ear infections, the first step is to work out exactly which type of ear infection they are getting, because the treatment options are not the same.

What do we mean by recurrent ear infections?

In children, the commonest pattern is recurrent acute otitis media. This means repeated infections of the middle ear, behind the eardrum. A commonly used definition is 3 or more episodes in 6 months, or 4 or more in 12 months.

A smaller number of children have recurrent otitis externa, which is different. Otitis externa is infection or inflammation of the ear canal, rather than the middle ear. This page is mainly about recurrent acute otitis media, because that is usually the more significant and more common ENT problem in younger children.

Why do children get recurrent acute otitis media?

Children are more prone to middle ear infections because the Eustachian tube — the small passage connecting the middle ear to the back of the nose — is shorter, more horizontal and less efficient in young children. That makes it easier for infection and inflammation associated with coughs, colds, and nursery exposure to affect the middle ear. Most episodes settle with time, but some children are simply unlucky and get them repeatedly.

Enlarged adenoids can also be part of the problem in some children. The adenoids sit close to the opening of the Eustachian tube, and if they are enlarged they can interfere with how the middle ear ventilates. This is one reason why recurrent middle ear infections, glue ear, nasal blockage, snoring, and adenoid problems can overlap. In some children, the adenoids may need to be addressed as part of the overall treatment plan.

Household smoking is also important. Passive smoke exposure increases the risk of ear infections in children, so a smoke-free home environment really does matter.

Many ear infections are triggered by viral upper respiratory infections, which is one reason they are so common in young children. However, some of the bacteria that can cause middle ear infections are ones that children are routinely immunised against. For that reason, it is important that children are kept up to date with their routine immunisations. This will not prevent every ear infection, but it is an important part of reducing the risk of some bacterial infections.

What symptoms do children usually get?

With recurrent acute otitis media, children often have repeated episodes of:

• sudden ear pain

• fever

• irritability or disturbed sleep

• reduced hearing during the infection

• poor appetite

• sometimes discharge from the ear if the eardrum bursts

Does recurrent ear infection affect hearing?

During an acute middle ear infection, hearing often becomes temporarily reduced because the middle ear fills with infected fluid. Between infections, some children also develop persistent fluid behind the eardrum, sometimes called glue ear, which can affect hearing for longer.

I usually separate these issues carefully in clinic:

• recurrent acute otitis media means repeated infections

• glue ear means fluid that stays behind the eardrum and affects hearing

They can overlap, but they are not exactly the same problem. As you are having a separate page for glue ear and grommets, that can be covered in more detail there.

Could there be an underlying problem with the immune system?

This is a common and understandable worry for parents. In the vast majority of children with recurrent acute otitis media, there is not an underlying immune deficiency. Recurrent ear infections are usually explained by age, exposure to viral infections, Eustachian tube immaturity, nursery attendance, adenoids, and environmental factors such as passive smoke exposure.

That said, if infections are unusually severe, involve other parts of the body repeatedly, are associated with poor growth, or there are other concerning features, then a broader assessment may sometimes be appropriate. Most children, however, do not turn out to have a serious immune problem.

How are recurrent acute middle ear infections treated?

Treatment depends on how frequent the infections are, how severe they are, the child’s age, whether hearing is affected between episodes, and how disruptive the problem has become.

1. Treating each episode as it happens

For many children, the simplest approach is to treat each infection as it comes. Most children improve within a few days without antibiotics, and pain relief is often the main early treatment. Antibiotics are used more selectively, depending on age, severity and how the child is doing.

2. A longer course of antibiotics

In some children with genuinely frequent recurrent acute otitis media, a longer prophylactic course of antibiotics may be considered. A dose of oral antibiotics, three times a week, for around 12 weeks can reduce how often a child has an infection, although infections can still occur during that period and may still need treatment.

This is not the right option for every child. The possible benefit has to be balanced against side effects, antibiotic resistance, and the fact that some children improve naturally over time.

3. Grommets

For selected children, grommets may be a useful option. Grommets are tiny ventilation tubes placed in the eardrum under a short general anaesthetic. In recurrent acute otitis media, they can reduce the build-up of pressure and infected fluid behind the eardrum and may reduce how severe episodes are.

When might surgery be considered?

Surgery is not needed for every child with repeated ear infections. Many children improve with time, and some are best managed by treating each infection as it comes.

I start thinking more seriously about procedural treatment when:

• infections are happening very frequently

• episodes are particularly painful or disruptive

• there is repeated eardrum rupture or discharge

• hearing is not fully normal between infections

• there is a significant impact on sleep, nursery or school attendance, or family life

• enlarged adenoids or ongoing middle ear fluid are part of the wider picture

In some children, surgery may involve grommet insertion, and in others it may also be appropriate to address the adenoids if they are contributing to the problem.

What about recurrent otitis externa?

A smaller group of children get repeated otitis externa, which is different from middle ear infection. This affects the skin of the ear canal and often causes:

• ear pain, especially when the outer ear is touched

• itching

• discharge

• blockage or muffled hearing

Recurrent otitis externa is more often linked to skin irritation, eczema, moisture, swimming, repeated use of cotton buds, or narrow ear canals rather than to Eustachian tube problems. Treatment is therefore different and usually focuses on careful cleaning when needed, topical ear drops, and reducing irritation or moisture in the canal.

Will my child grow out of recurrent ear infections?

Very often, yes. As children grow, the Eustachian tube matures and ear infections often become less frequent. That is one reason why not every child needs surgery. The challenge is deciding when the pattern has become frequent or disruptive enough that a more proactive treatment plan is justified.

When should urgent medical attention be sought?

Urgent assessment is important if a child has:

• severe pain that is not settling

• swelling, redness or tenderness behind the ear

• a child who is unusually drowsy or very unwell

• new facial weakness

• repeated vomiting with illness

• persistent high fever or concern about dehydration

Serious complications such as mastoiditis are rare, but they do happen and need urgent treatment.

How do I decide on the best treatment?

There is no single best treatment for every child with recurrent ear infections.

Some children are best managed conservatively. Some benefit from a longer antibiotic strategy. Some are better candidates for grommets, particularly if the pattern is frequent, severe or associated with middle ear fluid and hearing issues. Some may also benefit from treatment of the adenoids if these are contributing to the problem.

The right plan depends on the child’s symptoms, age, examination findings, hearing, and how much the problem is affecting day-to-day life.
