Tumors are rare, but can grow on the tonsils. You should see your doctor when you or your child suffer the common symptoms of infected or enlarged tonsils or adenoids. Your physician will ask about problems of the ear, nose, and throat and examine the head and neck. He or she will use a small mirror or a flexible lighted instrument to see these areas. X-rays are sometimes helpful in determining the size and shape of the adenoids.
Blood tests can determine problems such as mononucleosis.
Bacterial infections of the tonsils, especially those caused by streptococcus, are first treated with antibiotics. Such obstruction to breathing causes snoring and disturbed sleep that leads to daytime sleepiness in adults and behavioral problems in children. Some orthodontists believe chronic mouth breathing from large tonsils and adenoids causes malformations of the face and improper alignment of the teeth. 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.
