Tonsils and Adenoids

As part of our immune system, tonsils and adenoids are on the body’s first line of defense. They “sample” bacteria and viruses that enter the body through the mouth or nose, at the risk of their own infection. But at times, they become more of a liability than an asset and may even trigger airway obstruction or repeated bacterial infections.

Tonsils and adenoids are two masses of tissue that are similar to the lymph nodes or “glands” found in the neck, groin, and armpits. Tonsils are the two masses on the back of the throat. Adenoids are high in the throat behind the nose and the roof of the mouth (soft palate) and are not visible through the mouth without special instruments.

The most common problems affecting the tonsils and adenoids are recurrent infections (throat or ear) and significant enlargement or obstruction that causes breathing, swallowing, and sleep problems.

Abscesses around the tonsils, chronic tonsillitis, and infections of small pockets within the tonsils that produce foul-smelling, cheese-like formations can also affect the tonsils and adenoids, making them sore and swollen. Tumors are rare, but can grow on the tonsils.

Bacterial infections of the tonsils, especially those caused by streptococcus, are first treated with antibiotics. Sometimes, removal of the tonsils and/or adenoids may be recommended if there are recurrent infections despite antibiotic therapy, and/or difficulty breathing due to enlarged tonsils and/or adenoids. Such obstruction to breathing causes snoring and disturbed sleep that leads to daytime sleepiness in adults and behavioral problems in children.

Chronic infection can affect other areas such as the eustachian tube – the passage between the back of the nose and the inside of the ear. This can lead to frequent ear infections and potential hearing loss. Recent studies indicate adenoidectomy may be a beneficial treatment for some children with chronic earaches accompanied by fluid in the middle ear (otitis media with effusion).

In adults, the possibility of cancer or a tumor may be another reason for removing the tonsils and adenoids. In some patients, especially those with infectious mononucleosis, severe enlargement may obstruct the airway. For those patients, treatment with steroids (e.g., cortisone) is sometimes helpful.
