腭咽闭合功能的临床评估在很大程度上依赖于听觉感知判断，而这些判断可以通过对腭咽瓣膜的仪器检查来支持。目前的许多仪器技术难以解释，昂贵，和/或临床医生无法获得。在这份报告中提出了一种微创和廉价的方法来评估腭咽闭合功能，该方法已经在我们的实验室成功地用于一些潜在的难以测试的客户。该技术是一种气动机械方法，涉及到使用双管状鼻插管感测鼻塞压力(N-ramp)，即在前鼻孔感应的局部压力。通过监测N斜波信号，可以在语音产生期间确定腭咽闭合端口的状态(打开或关闭)。文中列举了4个案例，以支持其临床应用价值。
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 a number of 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.
