Question
A four-year-old child has adenoid hypertrophy with a nasopharyngeal layer thickness of 3 millimeters. What are the causes of pediatric adenoid hypertrophy?
Answer
Adenoid hypertrophy in children is usually caused by acute upper respiratory tract infections, leading to the hyperplasia and hypertrophy of the nasopharyngeal lymphatic tissue; the hyperplastic and hypertrophic nasopharyngeal lymphatic tissue blocks the posterior nares, causing the nasal sinus mucosal film to stagnate, thereby triggering chronic rhinitis and sinusitis; the accumulated mucus secretions of chronic rhinitis and sinusitis accumulate in the nasopharynx, and the inflammatory mediators and inflammatory cells further stimulate the hyperplasia and hypertrophy of the nasopharyngeal lymphatic tissue. This creates a vicious circle vicious circle between adenoid hypertrophy and chronic rhinitis and sinusitis. This is the most common factor in pediatric adenoid hypertrophy. As for allergic rhinitis, it does not occur very frequently in children, so allergic rhinitis can only be ranked second.
