Pharyngeal tonsillar hypertrophy

Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

Authoring team

The adenoids are situated on the posterior wall of the nasopharynx in young children.

They begin to atrophy at about 6 years of age and have disappeared completely by the age of about 15.

However if a young child - between 1 and 4 years - suffers recurrent upper respiratory tract infection they may hypertrophy and become symptomatic because of consequent nasal and eustachian tube obstruction.

Treatment if indicated is adenoidectomy


  • lymphoid tissue known as the adenoids or the pharyngeal tonsils occupies the posterosuperior surface of the nasopharynx and is part of a larger collection of lymphoid tissue known as Waldeyer's ring.
