A barium pharyngogram was incorporated into the multiview videofluoroscopic evaluation of the velopharyngeal portal in 195 subjects in order to assess its usefulness in demonstrating competence or incompetence. Reflux of barium was always associated with a velopharyngeal gap and/or hypernasality; however, the absence of reflux was not similarly diagnostic. The pharyngogram proved to be useful in confirming the presence of a palatal or pharyngeal-flap fistula. While it is helpful in assessing velopharyngeal closure in selected cases, it should not be used in the absence of other information.
在195名受试者的多视角视频荧光镜检查腭咽口评估中纳入了钡剂咽造影，以评估其在显示腭咽闭合功能正常或异常方面的效用。钡剂反流总是与腭咽间隙和/或高鼻音相关；然而，无反流情况则没有类似的诊断价值。咽造影被证明有助于确认腭部或咽瓣瘘的存在。虽然它在某些特定病例中有助于评估腭咽闭合，但在缺乏其他信息的情况下不应使用。
