Glue Ear - Picture Summary

This leaflet gives a brief summary of glue ear.

See separate leaflet called Glue Ear for more detailed information.

  • Sound waves hit the eardrum, causing the eardrum to vibrate.
  • Vibrations of the eardrum pass on to tiny bones (the ossicles) in the middle ear - the hammer (malleus), anvil (incus) and stirrup (stapes). These transmit the vibrations to the cochlea in the inner ear.
  • The ear nerve (auditory nerve) carries sound signals from the cochlea to the brain.
The ear - normal hearing
  • The middle ear space behind the eardrum is normally filled with air.
  • This air space connects to the back of the nose by way of the Eustachian tube.
  • From time to time the narrow Eustachian tube opens to let air into the middle ear, and to drain any fluid out. This usually happens when we swallow or yawn.
  • Glue ear is a condition where the middle ear becomes filled with glue-like fluid.
  • Glue ear is common and probably relates to problems with drainage from the Eustachian tube.
Glue in middle ear
  • The main problem with glue ear is dulling (not complete loss) of hearing. The gluey fluid dampens the vibrations of the eardrum and bones in the middle ear.
  • The usual advice at first is to wait to see if the fluid drains on its own and air returns to the middle ear.
  • If the fluid goes and air returns to the middle ear then hearing returns to normal.
Glue ear clearing
  • Fluid drains and hearing is back to normal within three months in about half of cases.
  • Hearing is back to normal within a year in more than 9 in 10 cases.
  • Some children have several bouts of glue ear that cause short but recurring episodes of dulled hearing.

If your child's symptoms haven't gone after three months of a 'wait and see' approach, your doctor may suggest other options

Balloon treatment

For this treatment the child regularly blows up a special balloon, using their nose. This is called 'autoinflation'. It increases the pressure in the nose, and may help to open up the Eustachian tube and allow better drainage of the fluid. It tends to be tried in older children who can use the device to blow up the balloon.

Grommets may be advised if glue ear persists

  • A grommet is a tiny tube that is put into the eardrum.
  • A tiny cut is made in the eardrum under anaesthetic. The fluid is drained and a grommet is inserted. The grommet allows air to get into the middle ear and keeps the drainage path open.
  • Hearing improves immediately.
Grommet in place
  • Grommets normally fall out of the ear after 6-12 months. By this time the problem with glue ear has often gone away. The hole in the eardrum made for the grommet normally heals quickly when the grommet falls out.
  • Sometimes grommets need to be put in on two or more occasions if glue ear recurs.
  • Sometimes the adenoids are also removed to improve the drainage of the Eustachian tube. Adenoids are similar to tonsils but lie at the back of the nose near the opening of the Eustachian tube.
