[Simultaneous electromagnetic articulography and video endoscopy. A case contribution to the objective diagnosis of the velopharyngeal sphincter].

An objective examination of velopharyngeal sphincter function (VP) is possible using a variety of signal and pictorial methods to differing degrees. Video endoscopy and videofluoroscopy are the currently accepted clinical standard. With the help of a new concept described here it is possible both to analyze VP function in the midsagittal plane using electromagnetic articulography (EMA) and also to examine simultaneously the horizontal plane video endoscopically. This multidimensional analysis of VP function is presented in a case study of a healthy test person and the timing aspects of VP closure and transverse-sagittal ratio of VP port-diameters ist reported.
