Passavant's ridge was studied in 43 patients via multiview videofluoroscopy incorporating the simultaneous recording of speech. Ratings of the videotapes were made at full speed, in slowmotion, and by stop-framing. The following results were found: (1) Just as there are variable patterns of velopharyngeal closure, there were also variations in the way in which Passavant's ridge is positioned relative to the velum, and in the ridge's subsequent role in velopharyngeal narrowing or closure. (2) The ridge was the primary pharyngeal structure at the level of the velum that closed or locally narrowed the velopharyngeal portal in 37% of patients. (3) Passavant's ridge usually appeared as a structure encompassing both the lateral and posterior pharyngeal walls, and its presence was usually associated with active lateral pharyngeal wall motion. (4) Passavant's ridge was more prominent when the head was in the hyper-extended rather than the neutral position. (5) Passavant's ridge moved in a highly consistent manner, synchronous with velar movement.
通过结合语音同步记录的多视角视频荧光镜检查对43例患者的帕萨凡特嵴进行了研究。对录像带进行了全速、慢动作和定格评分。发现以下结果：（1）正如腭咽闭合存在多种模式一样，帕萨凡特嵴相对于软腭的位置方式以及该嵴在腭咽狭窄或闭合中的后续作用也存在差异。（2）在37%的患者中，该嵴是软腭水平处闭合或局部缩窄腭咽口的主要咽部结构。（3）帕萨凡特嵴通常表现为一个包含咽侧壁和后壁的结构，其存在通常与咽侧壁的主动运动相关。（4）当头部处于过度伸展而非中立位置时，帕萨凡特嵴更为突出。（5）帕萨凡特嵴以高度一致的方式移动，与软腭运动同步。
