Children with enlarged adenoids can be treated conservatively by nasal cleansing, nasal spray or oral medication. 1. Most of the adenoid hypertrophy in children is caused by allergic rhinitis, so you can use saline to wash the nasal cavity, timely removal of nasal secretions and allergens, or with the use of glucocorticosteroid nasal spray, such as mometasone furoate nasal spray, which can make the enlarged adenoids gradually shrink. 2. If the child does not cooperate with nasal cleaning or nasal spray, you can take oral antihistamines, such as cetirizine, or with oral leukotriene receptor antagonists, such as montelukast sodium, which can also contribute to the reduction of enlarged adenoids. If the symptoms of adenoid hypertrophy are more serious, or if the results of the above conservative treatments are unsatisfactory, it is necessary to take the child to the ENT department or pediatrics department of the hospital, so as to avoid delaying the condition.
