What are ear tubes?
Ear tubes, also known as myringotomy tubes, are small tubes that are surgically placed into your child's eardrum by an ear, nose and throat surgeon. The tubes are usually made of plastic or metal. The tubes are placed to help drain fluid out of the middle ear, the space between the ear drum and the inner ear, in order to reduce the frequency and severity of ear infections.
During an ear infection, fluid gathers in the middle ear, which can cause discomfort and affect your child's hearing. Sometimes, even after the infection is gone, some fluid may remain in the ear. The tubes help drain this fluid, and prevent it from building up.
Normally, the middle ears are ventilated by the Eustachian tubes, the canals that link the middle ear with the back of the nose. These Eustachian tubes help drain fluid and allow air into the middle ear space, equalizing the pressure inside the ear, but when they become swollen, the excess middle ear fluid cannot drain out. Ear tubes come in a variety of sizes, shapes and materials, but they're all designed to allow an alternative way to ventilate the middle ear.
About one million children each year have tubes placed in their ears. The most common ages are from 1 to 3 years old, but many older children also undergo the surgery.
Why are ear tubes recommended?
The insertion of ear tubes may be recommended by your child's physician and/or an ear, nose, and throat physician if your child has:
- frequent middle ear infections
- fluid in the middle ears for more than three or four months
- fluid in the middle ears contributing to hearing loss or speech delay
- chronic middle ear infections that do not improve with antibiotics
Once placed, ear tubes are usually successful in significantly reducing ear infections. Most children will get one or two infections a year, and the infected pus typically drains on its own, through the opening created by the tubes.
What to expect from ear tube placement
Myringotomy is the surgical procedure that is performed to insert ear tubes. Ear tube placement is usually an outpatient procedure. This means that your child will have surgery, and then go home that same day. The procedure usually takes about 15 minutes and is done under general anesthesia.
Myringotomy involves making a small opening in the eardrum to drain fluid and relieve pressure from the middle ear. A small tube is then placed in the opening of the eardrum to ventilate the middle ear and to prevent fluid from accumulating. The tubes usually fall out on their own after 9 to 12 months.
Fortunately, ear tubes require relatively little follow-up. After the surgery, children return to their surgeon's office a month after the procedure, then every six months after that until the ear tubes fall out. By that point, many children outgrow their ear problems and don't require additional sets of tubes.
