Grommets, also known as tympanostomy tubes or ventilation tubes, are small plastic inserts placed into the eardrum during a minor surgical procedure. In 2026, UK clinical guidelines recommend grommets primarily when a child or adult suffers from persistent middle ear fluid that does not resolve on its own, or when frequent acute infections significantly impact daily life. The goal of a grommet is to bypass a malfunctioning Eustachian tube, providing a constant supply of air to the middle ear and allowing any trapped fluid to drain.

The Chronic Fluid Criteria or Glue Ear
The most common reason for grommets in 2026 is a condition called otitis media with effusion, commonly known as glue ear.
The Three Month Rule
Hearing and Developmental Impact
If the fluid is causing a significant hearing loss, typically defined as a loss of 25 to 30 decibels or more in the better ear, grommets become a priority. In children, we also look for functional impacts, such as:
- Speech and Language Delay: Difficulty pronouncing certain sounds or a smaller vocabulary than expected for their age.
- Educational Struggles: Difficulty following instructions in a classroom environment.
- Social Withdrawal: A child becoming frustrated or quiet because they cannot hear their peers.
Recurrent Acute Infections
Grommets are also recommended for patients who do not have permanent fluid but suffer from frequent, painful, and acute infections.
In 2026, the threshold for surgery typically involves:
- Frequency: Three or more separate infections in six months, or four or more in one year.
- Severity: Infections that are particularly severe, lead to eardrum perforations, or require multiple courses of strong antibiotics.
- Complications: Any history of more serious issues, such as mastoiditis, which is an infection of the bone behind the ear.
The 2026 Surgical Procedure
The placement of grommets is one of the most common paediatric surgeries in the UK. It is a day case procedure, meaning the patient usually goes home the same day.
- Myringotomy: Under a short general anaesthetic for children, a tiny incision is made in the eardrum.
- Suction: The surgeon uses a micro suction device to remove the thick, glue like fluid from the middle ear space.
- Insertion: The grommet is placed into the incision, acting like a tiny rivet that keeps the hole open.
- Recovery: The procedure itself takes about 10 to 15 minutes. Most patients experience an immediate improvement in hearing as soon as they wake up.
What Happens After the Procedure
Grommets are a temporary solution designed to stay in place while the patient anatomy matures.
- Lifespan: Most grommets stay in the eardrum for 6 to 12 months.
- Natural Ejection: As the eardrum heals and grows, it naturally pushes the grommet out into the ear canal, where it eventually falls out.
- Closing the Gap: Once the grommet falls out, the small hole in the eardrum usually heals and closes over on its own within a few weeks.
To Summarise
Grommets are recommended in 2026 when persistent middle ear fluid causes significant hearing loss for more than three months, or when recurrent acute infections become unmanageable. By providing ventilation to the middle ear, these tiny tubes prevent the vacuum effect that leads to fluid buildup and reduce the frequency of painful infections. While surgery is always a last resort after watchful waiting, grommets remain a highly effective way to protect a child speech, hearing, and educational development.
If your child has had persistent hearing issues or three infections in the last six months, the next clinical step is to request a referral to an ENT specialist for a formal hearing test and a pressure test of the eardrum.
Will my child still get ear infections with grommets?
It is possible, but they are usually much less painful because the fluid can drain out of the tube rather than building up pressure. You may notice some discharge, which is often treated with antibiotic ear drops rather than oral medication.
Are there risks to the surgery?
The main risks are a small chance of persistent discharge from the ear or, very rarely, a small hole in the eardrum that does not close after the grommet falls out.
Can my child swim with grommets?
In 2026, many surgeons allow swimming in clean pool water without earplugs, but they often recommend plugs for soapy bath water or lake and sea water to prevent bacteria from entering the tube.
Does the surgery hurt?
The surgery itself is done under anaesthesia, so there is no pain. Afterward, some children feel a slight popping sensation or mild discomfort, but this is usually managed with a single dose of paracetamol.
Will the grommets affect my child hearing permanently?
No. Grommets are intended to restore hearing to its normal level by removing the fluid blockage. They do not cause long term hearing damage.
What if the grommet falls out too early?
If a grommet falls out within a few months and the fluid returns, it may need to be replaced. However, many children find that even a short period of ventilation allows their Eustachian tube to start working better.
