Grommets (ear tubes) are small tubes inserted into the eardrum to drain fluid and improve hearing, commonly used to treat glue ear.
 

The procedure:

• Performed under general anaesthetic

• The surgeon makes a tiny cut in the eardrum to remove trapped fluid

• A small grommet tube is placed into the eardrum to keep the middle ear ventilated

• The procedure takes about 15 to 20 minutes

• Usually done as a day surgery
   

Grommets typically stay in place for 6–12 months and fall out naturally as the eardrum heals. This helps reduce ear infections and improve hearing in children.
