Passavant's ridge was studied by means of videofluoroscopy and nasopharyngoscopy in 80 patients with hypernasal speech. In patients with Passavant's ridge an improvement of the sphincter function was found to be associated with an enlargement of the ridge. It was also observed that the ridge could disappear if complete velopharyngeal closure was achieved without surgical intervention of the ridge area. The results indicate that Passavant's ridge is of compensatory origin.
通过视频荧光镜检查和鼻咽镜检查对80例鼻音过重患者的帕萨万特嵴进行了研究。在有帕萨万特嵴的患者中，发现括约肌功能的改善与嵴的增大有关。还观察到，如果在未对嵴区域进行手术干预的情况下实现了完全腭咽闭合，嵴可能会消失。结果表明，帕萨万特嵴起源于代偿。
