The effectiveness of removing the adenoids in children to improve recurrent nasal symptoms and/or nasal obstruction has not been well studied. [1]
Waldeyer's tonsillar ring (pharyngeal lymphoid ring, Waldeyer's lymphatic ring, or tonsillar ring) is a ringed arrangement of lymphoid organs in the pharynx.Waldeyer's ring surrounds the naso-and oropharynx, with some of its tonsillar tissue located above and some below the soft palate (and to the back of the mouth cavity).
It is currently believed that bacterial biofilms play an integral role in the harboring of chronic infection by tonsil and adenoid tissue so contributing to recurrent sinusitis and recurrent or persistent ear disease. [1] Also, enlarged adenoids and tonsils may lead to the obstruction of the breathing patterns in children, causing apnea during ...
[5] [1] While they most commonly occur in the palatine tonsils, they may also occur in the adenoids, lingual tonsils and tubal tonsil. [3] [6] [7] Tonsil stones have been recorded weighing from 0.3 g to 42 g, [3] and they are typically small in size. However, there are occasional reports of large tonsilloliths.
Their name derives from their initial isolation from human adenoids in 1953. [ 3 ] They have a broad range of vertebrate hosts; in humans, more than 50 distinct adenoviral serotypes have been found to cause a wide range of illnesses , from mild respiratory infections in young children (known as the common cold ) to life-threatening multi-organ ...
