Glue ear is one of the most common childhood conditions, yet its symptoms are frequently mistaken for autism, ADHD, or language delay. If your child is awaiting an ASD assessment or struggling with communication, ruling out glue ear should be one of the first checks you make.
Glue ear (otitis media with effusion) happens when thick, sticky fluid builds up in the middle ear behind the eardrum. This fluid dampens sound transmission, causing mild to moderate hearing loss. Unlike an ear infection, glue ear is usually painless, so it can go unnoticed for months. A child may simply seem distracted, unresponsive, or "in their own world" — which is easily attributed to autism or other developmental differences.
These glue ear symptoms are easily mistaken for ASD, ADHD, or a language disorder.
Signs that are more specific to autism and less likely to be caused by glue ear alone.
A child can have both glue ear and autism. One does not rule out the other. But if glue ear is missed, it can delay speech and language support, make school feel overwhelming, and mask the true picture of a child's abilities. A simple hearing test can rule out glue ear as a contributing factor — or identify it as something that needs treating while the ASD assessment process continues.
The rule of thumb: if your child has had frequent ear infections, colds, or seems to hear inconsistently (hears some things but not others), push for a hearing test before concluding the difficulties are developmental. The test is free, painless, and takes about 20 minutes.
The NHS offers free hearing tests for children. Here is how the route usually works.
The newborn hearing screen is routine, but glue ear develops later. Ask your health visitor about a referral to audiology at any review appointment — you do not need to wait for a specific check.
Your GP can refer your child to the local NHS audiology or ear, nose and throat (ENT) department. Say clearly: "I am worried about my child's hearing because of glue ear, and I want a hearing test."
Some areas offer routine school-entry hearing checks (Reception or Year 1). If you suspect glue ear, do not wait for the school screen — request a test through your GP or health visitor now.
NHS children's hearing tests are designed to be child-friendly and low-stress.
Most glue ear resolves without treatment, but persistent cases have several options.
Most glue ear clears on its own within 3–6 months. Your GP or audiologist will monitor with regular hearing checks every 6–8 weeks. During this time, simple strategies like sitting closer, facing your child when speaking, and reducing background noise can help.
If glue ear persists beyond 3 months with significant hearing loss, NHS audiology may offer temporary hearing aids (bone conduction or air conduction). These keep sound reaching the inner ear while the fluid resolves naturally. Many children manage well with hearing aids during this period.
Grommets (ventilation tubes) are the most common surgical treatment for persistent glue ear. A small tube is inserted into the eardrum under general anaesthetic to drain fluid and equalise pressure. The procedure takes about 15 minutes. Grommets usually fall out on their own after 6–12 months as the eardrum heals.
If glue ear keeps coming back, the surgeon may recommend removing the adenoids (adenoidectomy) at the same time as grommet insertion. This reduces the chance of recurrence by removing tissue that can block the eustachian tube.
A hearing test does not replace an ASD assessment. Some children have both glue ear and autism — treating the glue ear can improve communication and attention, which then gives a clearer picture for the ASD assessment team.
If your child is already on the ASD diagnostic pathway, tell both the audiology team and the ASD assessment team about any glue ear concerns. This helps avoid misattribution: a child who does not respond to their name may not be showing social difficulty — they may simply not have heard it.
If your child has frequent ear infections, is in pain, has discharge from the ear, or you suspect a perforated eardrum, see your GP or call 111 promptly.
