What was measured
Visual recording of the mucosa of the pharyngoesophageal segment (PES) performed with High speed video endoscopy (HSV) during the phonation of the vowel "a".The video recordings of the PES were made with a 90° rigid HSV system Wolf 5562 Hres ENDOCAM (frame rate: 4000 fps, resolution: 256×256 pixels). All subjects phonated the vowel "a" at a comfortable pitch and volume. Visual assessment of the HSV recordings was performed using the protocol including the assessments of the overall quality of the recordings (assessability, brightness and focus) and the assessments of anatomical and morphological features of the PES: amount of saliva, visibility and shape of the PES, location of visible vibration, presence of a mucosal wave and regularity of the vibration.
