ADENOIDS
Nature intends that we should breathe through the nose and has so arranged matters that the air is strained, warmed, and moistened as it passes through the nose. This is very important.
Unfortunately about 10 per cent of all children have adenoids which interfere with free breathing through the nose. So many serious results follow this condition that parents should learn something about adenoids and their treatment.
WHAT ARE ADENOIDS?

Inasmuch as adenoids are tucked away up behind the palate, and are therefore out of sight, it may be well to study the picture shown above.
The air passes into the lungs as shown by the arrows. At the place marked "A T" nature has provided a kind of moist cushion which helps to filter impurities out of the air. This cushion is formed of what doctors call "adenoid tissue" and is similar to that which makes up the tonsils. When this adenoid tissue grows abnormally large it forms what are known as "adenoids." From the position of these adenoids as shown on the diagram it will readily be seen how easily they interfere with proper nasal breathing.

WHAT ADENOIDS DO.
One of the first results of the growth of adenoids is mouth breathing. When this condition develops, the air breathed in reaches the throat and lungs in an unpurified condition. Moreover, it is not sufficiently warmed or moistened. In a short time, therefore, such children begin to suffer from repeated colds, and show the signs of a beginning of nasal catarrh. Unless proper treatment is now undertaken the condition soon gets worse, and the child's nasal breathing becomes more and more obstructed.
Children who suffer from adenoids are usually pale, often narrow-chested, and altogether are not as strong and robust as are normal children.
But this is by no means all of the harm done by adenoids. They affect the voice, disfigure the facial expression, interfere with hearing, give rise to night terrors, open the way for serious invasions by disease germs, and, through the development of chronic nasal catarrh, may lead to loss of the sense of smell.
The alteration of the facial expression is often so great that the child looks stupid and sometimes even half-imbecile.
