Abstract:
Two children in whom idiopathic hypernasality was diagnosed were referred for investigation of velopharyngeal function. Multiview videofluoroscopic assessments showed the tonsils prolapsing posteriorly during speech, preventing the palate from fully approximating the posterior pharyngeal wall. Tonsillectomy was recommended. Postoperative evaluations found that the hypernasal resonance was eliminated in both children.
