Grommet Insertion

A Grommet Insertion (also known as myringotomy with ventilation tube insertion) is one of the most commonly performed surgical procedures in children. It involves making a small incision in the eardrum and placing a tiny ventilation tube — known as a grommet — to allow air into the middle ear space. The procedure typically takes around 10–20 minutes and is performed under general anaesthesia.

What is a Grommet?

A grommet is a small, hollow tube inserted into the eardrum. It allows air to enter the middle ear, equalising pressure and preventing the accumulation of fluid behind the eardrum. Grommets are usually made of a soft, biocompatible plastic material and are designed to stay in place for several months before naturally extruding on their own.

Why is Grommet Insertion Performed?

1. Otitis Media with Effusion (Glue Ear)

  • This is the most common indication for grommet insertion.
  • Glue ear occurs when thick, sticky fluid accumulates in the middle ear space, causing hearing loss and, in children, delayed speech and language development.
  • Grommets allow the fluid to drain and restore normal hearing.

2. Recurrent Acute Otitis Media

  • Children who suffer from frequent ear infections may benefit from grommet insertion, which helps ventilate the middle ear and reduce the frequency of infections.

3. Eustachian Tube Dysfunction

  • When the Eustachian tube — which connects the middle ear to the back of the nose — does not open and close effectively, a grommet can compensate by providing an alternative route for middle ear ventilation.

4. Chronic Negative Middle Ear Pressure

  • Persistent negative pressure in the middle ear can lead to eardrum retraction and, over time, more serious complications. Grommet insertion relieves this pressure.

Expected Recovery

  • Children typically recover very quickly and go home on the same day.
  • Hearing improvement is often noticed immediately after the procedure.
  • Grommets usually stay in place for 6–18 months before falling out naturally as the eardrum heals.
  • Water precautions (avoiding submerging ears) are recommended — your surgeon will advise accordingly.
