Glue Ear in Children: Causes, Treatment and Hearing

Glue ear is one of the most common childhood conditions in the UK, yet many parents have never heard of it until their child is diagnosed. Understanding what it is, how it affects hearing, and what can be done about it makes a real difference.

If your child has recently been told they have glue ear, or you suspect something is off with their hearing, this guide walks through the essentials: what happens inside the ear, how it is diagnosed, what treatment options exist, and how to support your child at home and at school while things resolve.

What Is Glue Ear?

Glue ear, known medically as otitis media with effusion (OME), occurs when thick, sticky fluid builds up in the middle ear behind the eardrum. The middle ear is normally filled with air, which allows sound vibrations to pass through efficiently. When fluid replaces that air, sound transmission is muffled, and your child experiences a temporary drop in hearing.

It is remarkably common. Research suggests that around 80% of children will have at least one episode of glue ear by the age of ten. It is most frequent between ages two and five, which unfortunately overlaps with the period when speech and language skills are developing rapidly.

Glue ear is not the same as an ear infection, though infections can sometimes trigger it. The fluid itself is not infected, and your child may not be in pain. That is part of the reason it often goes unnoticed for weeks or months.

Recognising the Symptoms

Because glue ear is painless in most cases, the signs tend to be behavioural rather than physical. Parents often notice:

• Turning up the television louder than usual
• Asking "what?" frequently or not responding when called
• Difficulty following instructions, especially in noisy environments
• Speech that seems delayed or unclear for their age
• Becoming withdrawn, frustrated, or unusually clingy
• Ear pain or a feeling of fullness (though many children cannot describe this)

Teachers sometimes notice before parents do, because classroom environments with background noise make the hearing difficulty more obvious. If a teacher mentions that your child seems inattentive or struggles to follow group instructions, it is worth having their hearing checked.

How Glue Ear Is Diagnosed

Your GP can look inside the ear with an otoscope to check for fluid behind the eardrum. However, the most reliable test is tympanometry, which measures how the eardrum responds to changes in air pressure. A flat tympanogram strongly suggests fluid in the middle ear.

A hearing test (audiometry) will also be carried out to measure how much hearing is affected. Glue ear typically causes a mild to moderate conductive hearing loss of 20 to 40 decibels. That is roughly equivalent to having your fingers in your ears. For a child trying to learn language, that level of reduction is significant.

Treatment Options

Watchful Waiting

The NHS recommends a period of watchful waiting, usually three months, because most cases resolve on their own. During this time, you can help your child by speaking clearly, facing them when you talk, reducing background noise, and making sure their school is aware of the situation.

Grommets

If glue ear persists beyond three months and is significantly affecting hearing or development, your child may be offered grommets. These are tiny tubes inserted into the eardrum under general anaesthetic. The procedure takes about 15 minutes. Grommets allow air into the middle ear and let trapped fluid drain away. Hearing improvement is usually immediate.

Grommets typically fall out on their own after 6 to 12 months as the eardrum heals. Some children need a second set if glue ear returns. The operation is one of the most commonly performed childhood procedures in the UK and carries very low risk.

Temporary Hearing Aids

If surgery is not appropriate, or while waiting for a grommet appointment, your child may be fitted with temporary hearing aids. These amplify sound to compensate for the conductive loss. They are provided by NHS audiology and are well tolerated by most children. For more on how hearing aids work, see our guide to hearing aids for children.

Impact on Speech and Learning

The timing of glue ear matters. A brief episode at age eight is unlikely to cause lasting problems. Prolonged or repeated episodes between ages one and four, when language is being acquired at speed, can lead to speech delay, unclear pronunciation, and difficulty with phonics when reading begins.

This does not mean permanent damage. With appropriate support, most children catch up once their hearing improves. Speech and language therapy can help bridge the gap, and early years practitioners can adapt their approach to support a child with fluctuating hearing.

Supporting Your Child at School

If your child has glue ear, their school needs to know. Simple adjustments can make a considerable difference:

• Seating your child near the front of the class, close to the teacher
• Reducing background noise where possible (closing windows, using carpet or soft furnishings)
• Using visual aids alongside spoken instructions
• Checking your child has understood before moving on
• Allowing extra time for tasks that involve listening

Your child's teacher of the deaf or SENCO can draw up an informal support plan. If hearing loss is persistent and affecting educational progress, a more formal assessment of needs may be appropriate. Our newly diagnosed guide covers the steps for accessing support.

Glue Ear vs Permanent Deafness

Parents sometimes worry that glue ear will lead to permanent hearing loss. It is important to understand that glue ear causes conductive hearing loss, which is temporary and mechanical. It is different from sensorineural hearing loss, which involves the inner ear or auditory nerve and is typically permanent.

That said, some children have both. A child with an existing sensorineural hearing loss who develops glue ear will experience an additional, compounded drop in hearing. In these cases, prompt treatment is especially important. The NDCS glue ear page has further information on managing glue ear alongside permanent deafness.

When to See Your GP

Book an appointment if your child shows signs of hearing difficulty lasting more than a few weeks, if their speech seems to be falling behind, or if a previous episode of glue ear appears to have returned. Repeated episodes are common, and keeping a record of symptoms helps your GP understand the pattern.

If your child has already been diagnosed with any level of permanent hearing loss, mention any new changes in hearing promptly. What looks like a deterioration in their condition may actually be a treatable episode of glue ear on top of their existing loss.

For families whose children have been recently diagnosed with any form of hearing loss, our newborn hearing guide provides a helpful starting point for understanding the different types and what they mean.
