Measuring the correlation between adenoidal-nasopharyngeal ratio (AN ratio) and tympanogram in children

Antibiotherapy is effective in reducing adenoid size without signs and symptoms of infection. The reduction of the adenoids in size after 3 weeks of antibiotherapy has an positive effect on recovery of eustachian tube function but is not sufficient in patients with middle ear effusion. Early ventilation tube insertion may be an alternative therapy for the middle ear effusions not improving by 3 weeks medical therapy.
