The removal of tonsils and adenoids is probably the most frequent operation performed on children. Today it is generally accepted that healthy tonsils and adenoids serve as protective agents in the human body, as a defense against the invasion of bacteria into the bronchial tubes and the lungs. They serve as fortresses holding the infection in the nose and throat.

The decision as to removal of tonsils and adenoids then rests on whether these bodies have become a menace rather than a means of protection. If an operation is felt necessary, most pediatricians prefer to hold off the tonsillectomy until a child is approximately three years of age, for if they are removed too early there is often a regrowth of the tissue. Adenoid­ectomy may be performed at any age.

Since there may be separate indica­tions for the removal of tonsils and the removal of adenoids, it is wise to consider each category separately .
