NASOPHARYNX Enlarged adenoid

NASOPHARYNX Enlarged adenoid

The most common cause of an enlarged adenoid (there is only one nasopharyngeal adenoid, despite the common use of the term ‘adenoids’) is physiological hypertrophy in childhood. The size of the adenoid alone is not an indication for removal. Of more importance is the consequence of hypertrophy (e.g. nasal obstruction). Adenoid hypertrophy ( Figure 52.16 is often associated with hypertrophy of the other lymphoid tissues of Waldeyer’s ring. Of particular note, if excessive adenoidal hypertrophy causes blockage of the nasopharynx in association with tonsil hypertrophy , the upper airway may become compromised during sleep causing, obstructive sleep apnoea (OSA).
