Grommets are tiny tubes, about the size of a grain of rice, that a surgeon places in a child's eardrum. They help drain fluid from the middle ear and let air in. This can improve hearing and reduce ear infections.
Key facts
Yes, grommet surgery is one of the most common operations in children. Many children have them at some point.
Most often children between the ages of 1 and 3 with persistent 'glue ear' (fluid in the ear) or frequent ear infections. It is less common in older children and adults.
A doctor will look inside the ear with a special light (otoscope) and may do other tests to check how the ear is working.
The tests are straightforward and painless. For young children, the hearing test may be done as a game, like turning their head toward a sound. If glue ear is found, your doctor will discuss whether watchful waiting or grommets might help.
Treatment often starts with watchful waiting because many cases of glue ear get better without surgery. If problems last more than 3 months or cause significant hearing loss, grommets may be offered.
If glue ear does not clear on its own, surgery to insert grommets is the main treatment. The operation is done under general anesthesia and takes about 15 minutes. The surgeon makes a tiny cut in the eardrum, removes any fluid, and places the grommet. Hearing often improves right away.
After grommet surgery, most children feel better quickly. Keep water out of the ears for the first few weeks to prevent infection. After that, many doctors say children can swim with earplugs or a swim cap, but it is best to ask your surgeon.
No special diet is needed. Encourage a healthy, balanced diet to support overall health. Exercise is fine as soon as your child feels ready.
Living with hearing problems can be frustrating for children, especially if they have trouble at school or with friends. Grommets often improve hearing and social confidence. If your child feels upset about the surgery or about their ears, talk to your doctor or a child psychologist.
Not completely, but you can lower the risk by breastfeeding (if possible), keeping your child away from cigarette smoke, avoiding bottle feeding lying down, and making sure your child gets recommended vaccinations.
The pneumococcal vaccine and the flu vaccine may help reduce the chance of ear infections. Ask your doctor about the vaccination schedule.
There is no routine screening for glue ear. If you notice hearing problems, see your doctor.
For most children, grommets are a safe and effective way to improve hearing and reduce ear infections. They usually fall out on their own, and many children outgrow the need for them. With proper care, the outlook is excellent.
