Patient's question:
A 4-year-old child has adenoid hypertrophy, with a nasal pharyngeal layer thickness of 3MM. How is the child's adenoid hypertrophy caused?Doctor's answer:
1. Acute upper respiratory tract infection2. Chronic sinusitis
3. Allergic rhinitis
Adenoid hypertrophy in children is often triggered by acute upper respiratory tract infections, leading to hyperplasia and thickening of lymphoid tissue in the nasopharynx. When the hypertrophied lymphoid tissue blocks the posterior nasal aperture, it causes stagnation of the nasal and sinus mucus blanket, which in turn leads to chronic rhinitis and sinusitis. The purulent secretions of chronic rhinitis and sinusitis accumulate in the nasopharynx, and the inflammatory mediators and inflammatory cells within them further stimulate the hyperplasia and thickening of lymphoid tissue in the nasopharynx.
In this way, adenoid hypertrophy and chronic rhinitis and sinusitis form a vicious cycle of mutual causation. This is the most common factor for adenoid hypertrophy in children. As for allergic rhinitis, its incidence rate in children is not high, so it can only be ranked second.
