No clear relationship between the two has been found. Mometasone furoate nasal spray can be sprayed inside the nose to improve nasal ventilation, and antihistamines can be used. After aggressive treatment, the patient’s symptoms of adenoid hypertrophy and allergic rhinitis will improve, and if necessary, surgery will be needed to ablate the enlarged and hypertrophied adenoids. If you have allergic rhinitis, it is especially easy to combine with adenoid hypertrophy because the nasal mucosa is very sensitive and the nasal mucosa often flows backwards, stimulating the nasopharynx and easily leading to glandular hyperplasia and enlargement.
