Large adenoids can cause nasal obstruction and be associated with glue ear.
There are four areas of tissue at the back of the throat which are concerned with the development of defences against infection in early infancy. These are the right and left tonsils, the base of the tongue and the adenoids. The adenoids are located above the tonsils, at the back of the nose. They get larger between birth and four years of age and then become progressively smaller. By adulthood they have disappeared altogether.
