Ear tubes are plastic and shaped like a hollow spool. Doctors suggest tubes for children who have repeat ear infections or when fluid stays behind the eardrum. The child is unconscious under general anesthesia for this surgery.
Tubes can help with ear infections because they:
Tubes can be inserted in an outpatient surgery clinic. Children usually recover quickly and have little pain or other symptoms after surgery. Children can usually go home within 1 to 2 hours after the surgery. Your child will probably be able to return to school or child care the next day.
Follow-up visits to the doctor after a child has tubes inserted are very important. We will check to see whether the tubes are working and whether the child’s hearing has improved.
While the tubes are in place, the child needs to take extra care. Keep water from getting in the ear when your child takes a bath or a shower or goes swimming. The ear could get infected if any germs in the water get into the ear. We advise use of ear plugs following ear tube placement.
Tubes normally remain in the ears for 6 to 12 months. They often fall out on their own. If the tubes don’t fall out on their own, your child may need surgery to remove them. After the tubes are out, watch your child for signs of ear infection or fluid behind the eardrum.
Placing tubes in the ears drains the fluid and ventilates the middle ear. Tubes may keep ear infections from recurring while the tubes are in place. They also keep fluid from building up behind the eardrum. Doctors consider surgery to insert tubes:
Ear tubes often restore hearing. While the tubes are in place, they often prevent buildup of pressure and fluid in the middle ear. And they can reduce pain. Tubes may keep ear infections from recurring while the tubes are in place. But infections may return after the tubes are gone.
Minor complications occur in up to half of the children who have tubes inserted. Usual complications include:
>> The tube may become blocked, allowing ear fluid and infections to return.
>> The tube may slip out of place, possibly falling into the middle ear (rare).
>> Tissue may form behind the eardrum (cholesteatoma). This is also rare.
