[The correlation between adenoid hypertrophy and allergic rhinitis].

Adenoid tissue are the major constituent of Waldeyer's ring which are physiologically natural defense mechanism of the body against inhaled allergens and microorganisms.In all children, the volume of the adenoid increases with age with a maximal volume in the age group of 5-6 years, followed by a gradual decrease in volume by the age of 8-9 years.Allergic rhinitis is a non-infectious chronic inflammatory disease of nasal mucosa mediated by immunoglobulin E and involved by a variety of immunocompetent cells (T, B lymphocytes, mast cells, etc.) after atopic individual contact with allergens.Adenoid hypertrophy and allergic rhinitis are common and frequently-occurring diseases in children. Both of them may exist simultaneously and may cause similar clinical symptoms. This paper reviews the relationship between adenoid hypertrophy and allergic rhinitis.
