adenoids

Collections of overgrown gland-like tissue, present on the back wall of the nose above the tonsils in children, which shrivel and disappear in adolescence or early adult life. The adenoids contain LYMPHOCYTES and are part of the body's defence (immune) system.

Patient discussion about adenoids

Q. When should the tonsils and/or adenoids should be removed?

A. Currently the tonsillectomy is recommended in the presence of 6 episodes of throat infection (Group A strep pharyngitis) in one year or 3-4 episodes in each of 2years. Adenoidectomy may be recommended when tympanostomy tube surgery (http://en.wikipedia.org/wiki/Tympanostomy_tube) failed to prevent ear infection.

Another thing to consider is the presence of oral breathing - the constant use of the mouth for breathing in small children may lead to malformation of the facial bones that would necessitate more extensive surgeries later in life.
