Laryngostrobovideography using a flexible laryngofiberscope performed in conjunction with the phonatory examination.

Abstract

The phonatory examination was performed while monitoring vocal fold vibration by laryngo strobovideography. Vocal fold vibration was video-taped by a laryngostroboscope and flexible laryngo fiberscope inserted through the nasal cavity. Simultaneously, the phonatory examination was conducted with a phonation analyzer. The data were entered into a personal microcomputer via an A/D converter and analyzed to obtain the parameters of sound pitch, sound intensity and mean expiratory air flow volume, which were superimposed on the color video monitor screen.

Clinical Experience With a New Type of Rhino‐Larynx Electronic Endoscope PENTAX VNL‐1530

“…Stroboscopic examination is the most practical way to determine the vibratory mode of the vocal folds during phonation in the field oflaryngology (Yoshida et al, 1979;Saito et al, 1978;Fukuda et al, 1990). However, it is difficult to keep a record of stroboscopic images using an electronic endoscope employing the RGB sequencing sys-RHINO-LARYNX ELECTRONIC ENDOSCOPE tem.…”
