Abstract
A prospective study of multiview videofluoroscopy was performed on 50 patients with clinically suspected velopharyngeal insufficiency to determine which views are helpful, so that radiation dosage might be reduced. The lateral view alone was insufficient: In 11 patients, velopharyngeal insufficiency was demonstrated on the basal or Towne view when the lateral view appeared normal. The Towne view demonstrated the velopharyngeal portal better than the basal projection when the adenoids were large. The basal view should be reserved for the few cases in which the Towne and lateral projections give insufficient information.
