Tonsils are lymphoid tissue aggregates positioned near the entrance of the digestive and respiratory tracts, where they contribute significantly to immune defense. These structures initiate the first immunological response to inhaled or ingested pathogens.[1] The lymphatic tissues of the oropharynx form a circumferential arrangement known as the Waldeyer ring, which includes the palatine tonsils, commonly referred to as “the tonsils,” as well as the adenoid, lingual, and tubal tonsils.[2] Tonsils serve as key immunological sentinels, particularly during early life, and are frequently involved in infectious and inflammatory conditions such as tonsillitis and peritonsillar abscess. The tonsils are among the most commonly excised lymphoid organs in otolaryngologic surgery because of their propensity for recurrent infection and hypertrophy. A thorough understanding of tonsillar anatomy and function enables clinicians to diagnose head and neck infections more accurately and determine appropriate indications for surgical intervention.
