other (non) invasive procedures...………………………..
Videostroboscopy of the vocal folds can be performed by means of placing a rigid endoscope on the tongue or by introducing a flexible endoscope through the nose. Most often the rigid endoscope offers a better and clearer view. The stroboscopic light source is triggered by a microphone signal and enlightens the glottal cycle with a small delay (figure 1). As such the videostroboscopy offers a slow motion of the glottal vibration pattern.
