Not all children have enlarged adenoids. Every child has adenoids, which are often located in the nasopharynx and may develop gradually as they get older. The adenoids may develop gradually as they get older, reaching a peak at age 5-6 and gradually shrinking at age 9-10. In this process, some children often catch colds and fevers, and the adenoids become enlarged and hypertrophied, leading to obvious clinical symptoms in children, such as nasal discomfort and runny nose, which parents always think are caused by colds, but are actually caused by adenoid hyperplasia and hypertrophy. If the child’s condition does not improve with the simple application of medication, consider ablation surgery through low-temperature plasma to dispose of the hyperplastic and enlarged adenoids, and the clinical symptoms will be significantly improved.
