Question
How is children’s adenoid hypertrophy caused?
Answer
The causes of pediatric adenoid hypertrophy mainly include acute upper respiratory tract infections, chronic sinusitis, and allergic rhinitis. Acute upper respiratory tract infections can trigger the hyperplasia of lymphoid tissue in the nasopharynx, leading to obstructed flow of mucus in the nasal sinus mucosal blanket, ultimately causing chronic rhinitis and sinusitis. The accumulation of mucus in chronic rhinitis and sinusitis further stimulates the hyperplasia of lymphoid tissue, forming a vicious circle. Additionally, although less common, allergic rhinitis is also one of the factors leading to adenoid hypertrophy.
