Acute middle ear infection in children

About acute middle ear infection

The middle ear

The middle ear is the space behind your eardrum. It contains three tiny bones that move when sounds reach them. These transmit sound waves through your middle ear to your inner ear. Usually, your middle ear is filled with air, but if you have inflammation, the space becomes filled with mucus. The Eustachian tube connects your middle ear with your throat and opens when you swallow. This allows air to pass up and down the tube from your throat to the middle ear and in the opposite direction. This equalises the air pressure inside your ear to the air pressure outside your ear. When it’s inflamed, the Eustachian tube doesn’t open properly and so mucus stays in the middle ear.

Middle ear infections are most common in children. Adults are affected too, but three-quarters of those diagnosed are children under the age of 10.

An acute middle ear infection comes on suddenly and typically clears up in about four days. The term acute refers to how long your child has the infection, not to how serious the condition is.

Symptoms of acute middle ear infection

An acute middle ear infection can be triggered soon after your child gets a cough or a runny nose. Symptoms can include:

  • earache
  • deafness
  • a high temperature
  • a general feeling of being unwell, including feeling sick and a loss of appetite
  • irritability
  • blood and pus coming out of his or her ear (if the eardrum bursts)

You may also notice your child tugging at his or her ear. As mucus and pus build up in your child's middle ear, he or she may feel as though their ear is blocked and it can be very uncomfortable. Eventually, the eardrum may burst as a result of the pressure, after this it's likely to be less painful. A burst eardrum usually heals by itself.

The symptoms of acute middle ear infection usually clear up on their own within four days. If you have any concerns about your child’s symptoms or if they get worse at any time, see your GP.

Causes of acute middle ear infection

Your middle ear is normally filled with air, but can become filled with fluid if you have a virus, such as a cold. This is because the Eustachian tube can become swollen or blocked and the fluid can't drain away. The fluid in your middle ear can then become infected with bacteria, which travel up the Eustachian tube from your nose or throat. White blood cells that come to fight the infection can build up in your middle ear as pus. This build-up of pus can cause ear pain and hearing problems.

Acute middle ear infections are very common in children. This is partly because their immune systems are still developing and they are less well equipped to deal with infections than older children and adults. It's also because the Eustachian tube isn't fully developed in young children – it's quite short and horizontal, and so fluid and mucus can build up in the middle ear more easily.

An acute middle ear infection can also be caused by enlarged tonsils and adenoids. The adenoids are two small lumps of tissue similar to the tonsils, which sit at the back of your child's throat, beside the Eustachian tubes. If your child's adenoids are enlarged, they can block the Eustachian tube or, if inflamed, can cause inflammation of the Eustachian tube entrances.

Other factors that can increase the chance of your child getting an acute middle ear infection include:

  • using a dummy
  • formula feeding rather than breastfeeding, particularly if your child lies down when they feed
  • passive smoking – if either parent smokes, a child is at higher risk

Boys tend to be affected more than girls and the condition is more common in winter than summer. Your child is also at increased risk if he or she has a lot of contact with other children, for example, at a nursery or playschool, or has lots of siblings. In addition, children who are born with a cleft lip or palate, or who have Down's syndrome are more likely to get middle ear infections.

Diagnosis of acute middle ear infection

Your GP will ask about your child's symptoms and examine your child. He or she may also ask about your child’s medical history. He or she will use an instrument called an otoscope to look at your child's eardrum. 

Your GP may refer you to have a tympanometry test, which is usually done by an audiologist – a technician or scientist who specialises in identifying and treating hearing and balance problems. This can measure how flexible your child’s eardrum is – if your child has an acute middle ear infection, his or her eardrum stiffens up because of the fluid behind it.

If your child is under three months old, your GP may advise that you take him or her to hospital for further assessment.

Treatment of acute middle ear infection


Often the best treatment for an acute middle ear infection is to relieve the symptoms with painkillers, such as paracetamol (eg Calpol) or ibuprofen (eg Nurofen for Children) while the inflammation clears up. Don’t give aspirin to children under 16. Always read the patient information leaflet that comes with your medicine and if you have any questions, ask your pharmacist for advice. However, if your child’s condition fails to clear up, or gets worse, see your child's GP.


Most often, acute middle ear infections clear up on their own within four days and no antibiotics are needed. For this reason, your GP may give you a ‘delayed prescription’, one which you can’t use until your child has had symptoms for at least four days. It’s advised to use antibiotics sparingly to prevent antibiotic resistance building up.

However, if your child has already had symptoms for four days, your GP may prescribe antibiotics to start straight away. Also, if your child is under two and with both ears infected, or has a very high temperature or perforated ear drum then antibiotics may be prescribed sooner.

If your child is very young, under three months, your GP may recommend starting antibiotics straight away as well as referring your child to a hospital for further treatment.

If your child does have antibiotics, it's important to complete the course even if their symptoms get better.

Decongestant or antihistamine medicines are unlikely to help.

Always ask your GP for advice and read the patient information leaflet that comes with your medicine.


If your child gets several acute middle ear infections in a six-month period, or if a burst eardrum takes longer than one month to heal, your GP may decide to refer him or her to an ear, nose and throat specialist. Your child may need surgery if he or she has recurrent infections (three or more infections within six months).

Surgery may involve a procedure called a myringotomy in which a small cut is made in your child's eardrum so that fluid can drain out. Ventilation tubes called grommets or tympanostomy tubes may also be inserted into the cut in your child's ear. These are small plastic tubes that allow air to get in and out of his or her ear. Ask your doctor for more information.

Prevention of acute middle ear infection

It’s important to make sure that all your child’s vaccinations are up to date, and take steps not to expose your child to tobacco smoke, including not smoking in your house or car.

You can also try, wherever possible, to prevent contact with unwell children to stop your child picking up an infection, as well as ensuring that your child washes his or her hands properly and has good basic hygiene.

Vaccines are currently being developed by scientists to help prevent acute middle ear infections. The vaccines, called pneumococcal conjugate vaccines (PCVs), aim to immunise young children against pneumococcal infections, which are a common cause of middle ear infections. Research has shown that one such vaccine may help to prevent acute middle ear infections, but more research is needed to prove it has a big enough effect.

Other research has shown that chewing gum that contains xylitol can reduce the number of acute middle ear infections in children.
