Adenoids are lymph glands at the back of the nose.

Sometimes children have adenoids so big that they have a blocked nose, so that they have to breathe through their mouths. They snore at night. Some children even stop breathing for a few seconds while they are asleep.
The adenoids can also cause ear problems by stopping the tube which joins your nose to your ear from working properly. For children over three years of age, removing the adenoid at the same time as putting grommets in the ears seems to help stop the glue ear coming back. Removing the adenoids may also make colds that block the nose less of a problem for your child.
Adenoids get smaller as you grow older, so you may find that nose and ear problems get better after a few years.
For some children, using a steroid nasal spray will help reduce congestion in the nose and adenoids, and may be helpful to try before deciding on surgery. Antibiotics are not helpful and only produce temporary relief from infected nasal discharge.
If we are taking adenoids out because of ear problems, we may put in grommets at the same time. If your child has sore throats or stops breathing at night, we may also take their tonsils out at the same time. We will tell you what these operations involve if we are going to do them.
Arrange for a week off school. Let us know if your child has a sore throat or a cold in the week before their operation – it may be safer to delay surgery for a few weeks.
Your child will be asleep for the operation. We will take out the adenoids through his or her mouth.
In some hospitals, adenoid surgery is done as a day case, so that the patient can go home on the same day as the operation. Some surgeons may prefer to keep children in hospital for one night. Either way, we will only let him or her go home when he or she is eating and drinking and feels well enough.
Most children need about a week off nursery or school. They should rest at home away from crowds and smoky places. Stay away from people with coughs and colds.
Adenoid surgery is very safe, but every operation has small risks. The most serious problem is bleeding, which may need a second operation to stop it. However, bleeding after adenoidectomy is very rare. It is very important to let us know well before the operation if anyone in the family has a bleeding problem.
During the operation, there is a very small chance that we may chip or knock out a tooth, especially if it is loose, capped or crowned. Please let us know if your child has any teeth like this.
Most children recover very quickly.
A small number of children find that their voice sounds different after the surgery. It may sound like they are talking through their nose a little. This usually settles by itself within a few weeks.
The child’s nose may seem blocked up after the surgery, but it will clear by itself in a week or so.
Your child may have sore ears. This is normal. It happens because your throat and ears have the same nerves. It does not mean your child has an ear infection.
Give painkillers as needed for the first few days. Do not use more than it says on the label. Do not give your child aspirin – it could make your child bleed.
