[The influence of birch pollen on adenoid hypertrophy in children with seasonal allergic rhinitis].

The adenoid is a part of Waldeyer's ring, the basic function of which is antibody formation, they react later against a great variety of antigens. Pediatric adenoidal obstruction of the nasal airway is associated with significant morbidity and is a frequent indication for surgery, but its relationship to allergy has not been often studied. To examine the influence of atopy on the adenoid hypertrophy we studied 9 children ages 4 to 8 years, who had hypersensitivity to birch pollen and the seasonal allergic rhinitis. We conclude that allergy and sensitivity to birch pollen and probably to other kinds of alrallergens is an important risk factor for a AH in children. Therefore, early prevention of exposure to them may help reduce occurrence of AH.
