Meeting Organ for ENT and Pediatric Pulmonology: Tonsils

Tonsils are lymphoid tissue structures positioned close to the entrance of the digestive and respiratory tracts and play a key role in our immune system. Together, the lingual tonsil at the posterior third of the tongue, the paired palatine tonsils laterally, the nasopharyngeal tonsil (adenoid) posterosuperior, and the paired tubal tonsils at the pharyngeal openings of the Eustachian tubes form a ring of lymphoid tissue called Waldeyer’s ring [1–5]. They are crucial in preventing infection and act as the first defense against ingested or inhaled pathogens [2].
