Adenoid hypertrophy is a common cause of airway obstruction in children; it may lead to mouth breathing, nasal discharge, snoring, sleep apnea, and hyponasal speech. It also contributes to the pathogenesis of rhinosinusitis and recurrent otitis media. However, the adenoid lies in the posterior nasopharyngeal wall and may act as a pad against the palate facilitating velopharyngeal closure, especially in patients with palatal abnormalities; Its presence can compensate for a short or poorly mobile palate. Following adenoidectomy, compensation is eliminated and velopharyngeal insufficiency (VPI) may result. Therefore, patients with palatal abnormalities (such as poor palatal mobility, short palate, occult submucosal cleft palate, scarred palate after previous tonsillectomy, and repaired cleft palate) are at high risk to develop hypernasality after complete adenoidectomy, and in such situations conservative or partial adenoidectomy is performed
