Adenoids are small tissues located at the back of the throat. They are similar to the tonsils, and are located right above them. Your tonsils can be seen if you look at the back of your throat, but the adenoids aren’t directly visible. Both adenoids and tonsils are part of the immune system, which helps to prevent and fight infection in your body.
The adenoids can cause problems if they become enlarged. Fortunately, they are not an essential part of the immune system and they generally can be treated by removing them.
Adenoids are present at birth. They grow until a child is between the ages of 3 and 5. Normally, they begin to shrink after around age 7. They shrink considerably in adulthood.
They’re located in the passage that connects the back of the nasal cavity to the throat. They produce antibodies to help your body fight off infections. They also help control bacteria and viruses that can enter through your nose. During the early years, adenoids help protect infants from infection. They trap bacteria and viruses when they enter the body.
Adenoids that become infected usually become enlarged, but return to their normal size when the infection subsides. However, in some instances, the adenoids remain enlarged, even after the infection is gone.
Enlarged adenoids can also be caused by allergies. Some children have enlarged adenoids from birth.
Enlarged adenoids can cause a number of symptoms, including:
The doctor will first ask about the symptoms your child is experiencing. Then your child will receive a physical exam. The doctor will use a special mirror and insert a small, flexible telescope (known as an endoscope) through the nose to view the adenoids.
Depending on what your doctor finds, your child may need a blood test to check for infection. In some cases, an X-ray exam of the throat may be necessary.
In severe cases, your child may need to undergo a sleep study. This will determine if they are suffering from sleep apnea. During the study, your child will sleep overnight at a facility while their breathing and brain activity are monitored using electrodes. The study is painless, but it can be difficult for some children to sleep in a strange place.
Treatment depends on how severe the condition is. If your child’s enlarged adenoids aren’t infected the doctor may not recommend surgery. Instead, the doctor may choose to simply wait and see if the adenoids shrink on their own as your child gets older.
In other cases, your doctor may recommend medication to heal enlarged adenoids. However, it’s common for enlarged adenoids to be removed. The procedure is fairly simple and doesn’t have many risks. This surgery is called an adenoidectomy.
If a child has been having frequent tonsil infections, the doctor might remove the tonsils as well. The tonsils and adenoids are often removed at the same time. It’s important for the adenoids to be removed, especially if your child is experiencing repeated infections that lead to sinus and ear infections. Adenoids that are very badly swollen can also lead to infections or middle ear fluid, which can temporarily cause hearing loss.
Your child will be given a mild sedative before surgery to help calm them. They will then be placed under general anesthesia. The surgery lasts no more than two hours.
After the adenoids are removed, your child might experience:
The doctor will prescribe an antibiotic to protect against any infection. Your child may also receive a mild pain reliever for the first few days. Children are also urged to drink cold, icy drinks, like milkshakes and ice cream, and to avoid any warm foods for the first seven days.
Symptoms should clear up in a few weeks.
It’s common for children to have enlarged adenoids. Be sure to have your child examined as soon as possible if you notice that they are experiencing any of the symptoms of enlarged adenoids. Enlarged adenoids are a very treatable condition and some cases can be treated with a simple antibiotic.
