title: Simultaneous evaluation of articulatory velopharyngeal function under different dynamic conditions with EMA and videoendoscopy.
abstract: Objective examination of velopharyngeal (VP) sphincter function has been described based on multiple methods. Videofluoroscopy and videoendoscopy represent today's clinical standard. A new concept of analysis of VP functioning is described using electromagnetic articulography (EMA) for midsagittal measurement of velar movement and videoendoscopy in a setting for simultaneous recording. Multidimensional analysis of VP functions using this setting is demonstrated for a normal subject. Timing aspects of VP closure and a transverse-sagittal ratio of VP port diameter are reported under different conditions of speech dynamics.
