Otitis media with effusion (OME)
A diagnosis of glue ear can usually be confirmed by using an instrument called an otoscope.
An otoscope is a small hand-held device that has a magnifying glass and a light source at the end. It's used to study the inside of the ear and can detect signs that usually indicate fluid inside the middle ear.
These include:
Further testsare usually only required if your child's symptoms persist for more than three months. The tests will often be carried out at your local ear, nose and throat (ENT) department and include:
These tests are discussed in more detail below.
Audiometry is a hearing test that uses a machine called an audiometer to generate sounds of differentvolumes and frequencies.
Your child will listen to the sounds through headphones and will be asked to respond when they hear them for example, by pressing a button.
By decreasing the sound level, the tester can work out the quietest sounds that your child can hear. Your child's ability to hear the different sounds can be seen on a chart called an audiogram.
Audiometry doesn't cause any discomfort and most children find it interesting.
Tympanometry is a test to determine how flexible the eardrum is. For good hearing, your eardrum needs to be flexible to allow sound to pass through it.
If the eardrum is too rigid for example, because there's fluid behind it sounds will bounce back off the eardrum, instead of passing through it.
During the test, a small tube with a soft rubber tip will be placed at the entrance of your child's ear and air will be gently blown down it. The tube measures the sound that's bounced back from the ear.
If most of the sound is bounced back, it will indicate to the tester that your child's eardrum is rigid and that they may have glue ear.
Find out what glue ear is, what causes it, how it's treated and the possible complications.
The most common sign of glue ear is hearing loss, which can affect one or both ears.
The exact cause of glue ear is unknown, but it seems to be caused by a problem with the Eustachian tube - a narrow tube that runs from your middle ear to the back of your throat.
A diagnosis of glue ear can usually be confirmed by using an instrument called an otoscope, which is used to study the inside of the ear and can detect signs that usually indicate fluid inside the middle ear.
Find out when treatment for glue ear is recommended and what treatment options are available. Hearing aids and grommets are the two main treatments for glue ear.
Read about the complications of glue ear, including delayed speech and language development, ear infection, thickening of the eardrum and a perforated eardrum.
It's not possible to prevent glue ear, but you can reduce your child's risk by breastfeeding rather than bottle feeding, and making sure your home is smoke-free.
