Abstract
Zur Feststellung des Öffnungs- und Schließungsvorganges der Tube während des Schluckens wurden an drei Affen simultan das Röntgenkinematogramm und das Elektromyogramm registriert. Dabei zeigte sich, daß sich die knorpelige Tube synchron zur Aktivität des M. tensor veli palatini für ca. 250 ms durch eine Bewegung der lateralen Wand nach außen öffnet. Daneben erweitert sich die pharyngeale Tubenöffnung für eine relativ lange Zeit synchron mit der Aktivität des M. levator veli palatini. Diese Zeitverzögerung zwischen den beiden Tubenabschnitten scheint die Pumpfunktion der Tube zu unterstützen. To determine the opening and closing process of the Eustachian tube during swallowing, the simultaneous recording of cineroentgenograms and electromyograms (EMG) was carried out in three monkeys. It was revealed that synchronous with the activity of the tensor veli palatini muscle, the cartilaginous tube opened for a very short time (ca. 250 ms) by an outward movement of its lateral wall. On the other hand, the pharyngeal orifice of the tube dilated for a relatively long time synchronous with the activity of the levator veli palatini muscle. These time lags between two parts of the tube seemed to help the pumping function of the tube.This publication has 6 references indexed in Scilit:
