analysis of vocal fold vibration by x ray Stroboscopy with multiple markers
Otolaryngology-Head and Neck Surgery, 1999Co-Authors: Toshiyuki Kusuyama, Hiroyuki Fukuda, Akihiro Shiotani, Hideki Nakagawa, Jin KanzakiAbstract:OBJECTIVE: To derive a more precise description of vocal fold vibration, experimental phonation of excised canine larynxes was studied.STUDY DESIGN AND SETTING: Multiple X-ray-positive markers were inserted, and their vibratory movement was observed with x-ray Stroboscopy with change of pitch and intensity. A histologic study was also carried out.RESULT: Regular waves were observed just above the lowest point of the lamina propria of the mucous membrane, which shifted upward at high pitch, but downward in high intensity.CONCLUSIONS: The starting point of the mucosal wave was confirmed on the lower surface of the vocal fold, histologically just above the lowest point of the lamina propria of the mucous membrane and shifted upward at high pitch, but downward in high intensity.SIGNIFICANCE: This is the first study investigating the starting point of mucosal wave in vocal fold vibration in a frontal plane using x-ray Stroboscopy, providing the evidence for the body-cover theory.

Stroboscopy versus high speed glottography a comparative study
Laryngoscope, 2007Co-Authors: Arno Olthoff, Christina Woywod, Eberhard KruseAbstract:Objectives: To evaluate and to compare the diagnostic value of videoStroboscopy (VS) and high-speed glottography (HGG) in dysphonic patients. Study Design: Randomized, prospective study. Methods: A total of 162 patients underwent indirect laryngoscopy using both methods (VS and HGG). The resulting 324 films were evaluated by two professionals (laryngologists, MDs) using a standardized protocol containing established criteria to classify vocal fold vibratory movement qualities. Results: The rating “not assessable” was mentioned significantly more often in VS than in HGG (P < .001). In HGG, methodologic failures were less frequent, and the length of investigation was shorter. Even if the agreement between the two raters was higher in HGG (54%) compared with VS (42%), both percentage values show a low accordance in diagnostic findings. Conclusions: Regardless of the method used (VS or HGG), perceptive evaluations of vibratory movements of vocal folds revealed a higher variability than assumed. This result supports the need for objective methods to analyze vocal fold vibratory movements. Therefore, real-time imaging of vocal fold vibratory movements using HGG will be necessary.
