Abstract: The palatine tonsils and adenoids are critical components of the immune system, strategically located in the upper aerodigestive tract to serve as the first line of defense against pathogens. The palatine tonsils, situated within the tonsillar fossa, are bordered by the palatoglossus and palatopharyngeus muscles, while the adenoid, a midline aggregation of lymphoid tissue, is located in the nasopharynx. Both structures are part of Waldeyer’s ring, which includes the pharyngeal, tubal, and lingual tonsils, and play a vital role in initiating immune responses, particularly during childhood. The tonsils produce IgG and IgA immunoglobulins, with peak immunological activity occurring between ages 4 and 10. Adenotonsillectomy, one of the most common surgical procedures in otolaryngology, is indicated for conditions such as recurrent tonsillitis, OSDB, and chronic adenoid hypertrophy. Diagnostic methods for adenoid hypertrophy include nasal endoscopy, radiography, and clinical grading systems, with nasal endoscopy considered the gold standard. Complications of adenotonsillectomy, though rare, include hemorrhage, velopharyngeal insufficiency, and Grisel’s syndrome. Postoperative pain management is crucial, particularly in pediatric patients. The immune system, comprising innate and adaptive immunity, relies on lymphoid cells such as B cells, T cells, and NK cells to combat infections. Immunoglobulins, including IgG, IgM, IgA, IgE, and IgD, play specific roles in immune defense, with IgG being the most abundant in newborns due to placental transfer. Understanding the anatomy, function, and clinical significance of the tonsils and adenoids is essential for effective diagnosis and management of related pathologies.
