It can cause deafness and repeated earache or infections, resulting in discharge from the ear.

What happens during grommet insertion?

Grommet insertion is usually performed under a general anaesthetic but a local anaesthetic can be used. The operation usually takes about twenty minutes.

Your surgeon will make a small hole in the eardrum and remove the fluid by suction. They will then place a plastic or metal grommet in the hole.

After grommet insertion

You should be able to go home the same day as your procedure. You may notice a significant improvement in your hearing.

Other than swimming, you should be able to return to normal activities after 24 hours.

The grommet will fall out of your ear by itself - after nine to twelve months for the plastic type and after about two years for the metal type.

Most patients make a good recovery from grommet insertion. As with any surgery there can be complications such as:

  • Pain
  • Bleeding

Specific complications of grommet insertion:

  • Fluid leaking from the ear
  • Ear discharge
  • Small hole left in the ear drum after the grommet falls out
  • Repeated build-up of fluid in the middle ear
