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.
对50例临床怀疑腭咽功能不全的患者进行了多视角视频荧光透视的前瞻性研究，以确定哪些视角是有帮助的，从而可能减少辐射剂量。仅侧位视图是不够的：在11例患者中，当侧位视图显示正常时，在基底位或汤氏位视图上显示出腭咽功能不全。当腺样体较大时，汤氏位视图比基底位投影能更好地显示腭咽口。基底位视图应保留用于汤氏位和侧位投影提供信息不足的少数情况。
