Adenoid Ear Infections

The adenoids are a type of lymph tissue in the upper throat with responsibility for fighting off infections. In some individuals, they also contribute to circumstances that trigger infection of the middle ear.

  1. The Facts

    • According to the National Institute on Deafness and Other Communication Disorders, middle ear infections (otitis media) begin with problems associated with the eustachian tubes, which normally ventilate the middle ear and equalize its internal pressure.

    Adenoid Infection

    • Although the adenoids fight infections, they may also become infected themselves. When they do, bacteria may travel from the adenoids to the nearby eustachian tubes, triggering otitis media.

    Adenoid Enlargement

    • The adenoids may also contribute to ear infections when they enlarge beyond their normal size and partially block the eustachian tubes, reports the MayoClinic.com. Adenoid enlargement sometimes results from infection, but may also occur naturally in some children, states the Merck Manuals Online Medical Library.

    Significance

    • Infection of the middle ear produces swelling that blocks the eustachian tube and leads to the development of pus, which can cause symptoms including pain and temporary hearing difficulties.

    Considerations

    • Children experience middle ear infections more frequently than adults. Reasons for this phenomenon include the shorter length of the eustachian tubes, which make bacterial access easier.
