Clinical evaluation of velopharyngeal function relies heavily on auditory perceptual judgments that can be supported by instrumental examination of the velopharyngeal valve. Many of the current instrumental techniques are difficult to interpret, expensive, and/or unavailable to clinicians. Proposed in this report is a minimally invasive and inexpensive approach to evaluating velopharyngeal function that has been used successfully in our laboratory for several potentially difficult-to-test clients. The technique is an aeromechanical approach that involves the sensing of nasal ram pressure (N-RamP), a local pressure sensed at the anterior nares, using a two-pronged nasal cannula. By monitoring the N-RamP signal, it is possible to determine the status of the velopharyngeal port (open or closed) during speech production. Four case examples are presented to support its clinical value.
腭咽功能的临床评估在很大程度上依赖于听觉感知判断，而腭咽瓣的仪器检查可为其提供支持。目前许多仪器技术难以解读、成本高昂，且临床医生无法使用。本报告提出了一种微创且低成本的评估腭咽功能的方法，该方法已在我们实验室成功应用于几位可能难以测试的患者。该技术是一种气动机械方法，使用双叉鼻插管来感知鼻冲压（N-RamP），即在前鼻孔处感知的局部压力。通过监测N-RamP信号，可以确定言语产生过程中腭咽口的状态（开放或关闭）。本文给出了四个病例示例以支持其临床价值。
