Grommet insertion (tympanostomy) involves placing a small ventilation tube through the eardrum to allow air into the middle ear and drain accumulated fluid (glue ear). It is one of the most common ENT procedures in children.
What is Glue Ear?
Glue ear (otitis media with effusion) is a build-up of thick, sticky fluid in the middle ear. It is the most common cause of hearing loss in children and often follows recurrent ear infections.
Symptoms
- Hearing loss (often noticed as inattention or learning difficulties at school)
- Delayed speech development in young children
- Ear fullness or discomfort
- Recurrent ear infections
The Procedure
Grommet insertion is performed under brief general anaesthesia, usually as a day procedure taking about 15 minutes. A tiny incision is made in the eardrum, fluid is suctioned, and the grommet tube is inserted. Hearing typically improves immediately.
Recovery
Children can usually return to school the following day. Grommets typically fall out on their own after 6–18 months. Water protection (earplugs for swimming) is recommended.
