What about adenoid hypertrophy?

  The adenoids, like the tonsils, are pediatric glandular tissue, and God gave each organ or tissue a certain function in the creation of man. However, when the adenoids are repeatedly irritated by inflammation, they can become hyperplastic in varying degrees. Degeneration of hyperplastic adenoids can occur in children around the age of 10, with complete degeneration occurring around the age of 13-14. Adenoids that do not completely degenerate are called adenoid remnants in adults. Overgrown and enlarged adenoids are called adenoidal hypertrophy in children.  The hypertrophic adenoids obstruct the posterior nostril and may cause compression of the eustachian tube by the round pillow, thus blocking the only airway between the middle ear and the outside world and contributing to the development of secretory otitis media in children. The hypertrophic adenoids hold a large number of bacteria, which reproduce and cause recurrent episodes of chronic rhinitis and sinusitis in children, with nasal congestion, runny nose, recurrent coughing and coughing up phlegm all being attributed to the adenoids. The culprit of snoring (snoring, restless sleep, open-mouth breathing) in children is adenoid hypertrophy, which is also a common cause of developmental delay in young children.
