Clinical Definition

Adenoid characteristics:

  • Nasopharyngeal Location: Behind the nasal cavity
  • Lymphoid Tissue: Part of Waldeyer's ring immune system
  • Age-Related: Largest in early childhood, typically regress with age
  • Nasal Obstruction: Can block nasal breathing when enlarged
  • Mouth Breathing: Hypertrophy promotes mouth breathing

Adenoid hypertrophy can cause chronic nasal obstruction, leading to mouth breathing, snoring, and sleep apnea, particularly in children.

Etymology & History

Adenoids have been recognized since ancient times, with their role in pediatric sleep-disordered breathing becoming well-established with the development of pediatric sleep medicine.

Reference Values & Interpretation

Normal Values

Normal adenoid size should not significantly obstruct nasal breathing or cause chronic mouth breathing patterns.

Abnormal Values

Abnormal adenoid anatomy includes hypertrophy causing significant nasopharyngeal obstruction, chronic nasal congestion, and promotion of mouth breathing.

How It's Measured

Adenoid anatomy is assessed through physical examination, flexible nasal endoscopy, and imaging studies to evaluate size and obstruction degree.

Role in Diagnosis

Adenoid assessment is crucial in pediatric sleep medicine, as adenoid hypertrophy is a primary cause of childhood sleep-disordered breathing.

Role in Treatment

Adenoid hypertrophy is treated with adenoidectomy, often combined with tonsillectomy (adenotonsillectomy) for pediatric sleep apnea treatment.
