There is disagreement regarding the usefulness of barium nasopharyngeal coating for clinical velopharyngeal evaluation. One hundred and thirty lateral videofluoroscopic studies performed both with and without barium at the same sitting were reviewed to evaluate multiple structural and functional characteristics of velopharyngeal valving behavior during speech production. Clinical ratings of hypernasality were also available for 105 of the patients studied by x-ray. Agreement between ratings of hypernasality and radiographic evidence of VP incompetency did not differ with respect to the presence or absence of barium. However, velopharyngeal incompetence was generally judged to be greater when the barium coating was used. The barium coating also provided more information as to the presence or absence of Passavant's ridge, generalized posterior pharyngeal wall movement, and palatal asymmetry. However, because the barium may produce artifacts or occasionally obscure structures, we recommend that lateral videofluoroscopy be performed both with and without barium.
关于钡剂鼻咽部造影在临床腭咽评估中的作用存在分歧。回顾了130例在同一次检查中分别使用和不使用钡剂进行的侧位录像透视研究，以评估言语产生过程中腭咽瓣运动的多个结构和功能特征。对于105例接受X线检查的患者，也有鼻音过重的临床评分。鼻音过重评分与腭咽功能不全的影像学证据之间的一致性，在有无钡剂的情况下并无差异。然而，使用钡剂造影时，腭咽功能不全通常被判定更为严重。钡剂造影还能提供更多关于帕萨万特嵴的有无、咽后壁的整体运动以及腭部不对称性的信息。然而，由于钡剂可能会产生伪影或偶尔使结构模糊不清，我们建议同时进行有钡剂和无钡剂的侧位录像透视检查。
