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. A specialist (otolaryngologist) places the tubes through a small
surgical opening made in the eardrum (myringotomy or tympanostomy). The child
is unconscious under
general anesthesia for this surgery.
Allow fluid to flow out of the middle ear through the
tube into the ear canal.
Clear the fluid from the middle ear and
Prevent future buildup of fluid in the middle ear
while they are in place.
Decrease the feeling of pressure in the
ears, which reduces pain.
What To Expect After Surgery
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. The doctor checks to see whether the tubes
are working and whether the child's hearing has improved.
Ask your doctor about ear protection for your child. He or she can tell you when the hole in the eardrum has healed and when it's okay to go back to regular water activities.
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.
Why It Is Done
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:
If a child has had fluid behind the eardrum in
both ears for more than 3 months and has significant hearing loss in both ears.
If a child has repeat ear infections.
How Well It Works
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:
A thickening of the eardrum over time. These
changes in the eardrum may affect hearing in a very small number of
Discharge of pus (otorrhea) from the ear. This is common
and can become an ongoing problem in some children.
Other possible complications:
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.
What To Think About
Some children who have tubes
inserted may need to have tubes reinserted.
Tubes may scar the
eardrum. Scarring may lead to minor hearing loss.
After surgery, a
child needs regular checkups to see that the tubes are working. In some cases,
the child may need
antibiotics to prevent or treat infections.
