<p class="abstract"><strong>Background:</strong> Adenoid hypertrophy (AH) is a common cause of upper airway obstruction and obstructive sleep apnea syndrome (OSAS) in children having major impact on child’s growth and development. Symptoms like nasal congestion, mouth breathing, nasal discharge, snoring, day time sleepiness, hyponasal voice, ear popping, and craniofacial abnormalities are observed. Adenoidectomy is considered the treatment of choice for symptomatic children. Co-existing medical illnesses and choice of surgical treatment is governed by the paediatricians and apprehensive parents. Need for conservative treatments in alleviating symptoms have been tried. Topical, intranasal administered, steroid preparations have been proven effective in the literature.</p><p class="abstract"><strong>Methods:</strong> In this prospective study, 35 symptomatic children (3-12 years) with adenoid hypertrophy were included. Each of the symptoms was scored from 0 (absent) to 4 (severe) over Visual Analogue Scale (VAS). Nasal obstruction index was calculated. Results of mometasone furoate nasal spray 100 microgram/day used once daily at the interval of 8 weeks and 12 weeks were analysed using statistical tests. </p><p class="abstract"><strong>Results:</strong> A statistically significant reduction in nasal obstruction index and other symptoms were noted at the end of third month follow up.</p><p class="abstract"><strong>Conclusions:</strong> Mometasone furoate nasal spray caused improvements in outcomes of nasal obstruction, snoring, total nasal symptoms, ear symptoms and overall quality of life.</p>
