Abstract: Adenoid hypertrophy and allergic rhinitis are common chronic inflammatory diseases of upper airway in children. In recent years，a number of studies have shown that there is a high co-morbidity rate between the two diseases and there may be a close relationship between them in terms of allergens，pathological changes and pathogenesis. In the process of clinical diagnosis and treatment，otolaryngologists need to deeply understand the internal relationship between adenoid hypertrophy and allergic rhinitis，in order to achieve long-term control of symptoms and get a better prognosis.
