videostroboscopy
Instrumental assessment technique using stroboscopic light to visualize vocal fold vibration patterns during voice evaluation.
Full Definition
Videostroboscopy is a specialized laryngoscopic examination that uses synchronized stroboscopic illumination to create the illusion of slow-motion vocal fold movement. This technique allows clinicians to assess vocal fold vibration patterns, mucosal wave propagation, and glottal closure patterns that are invisible to the naked eye during normal phonation. The procedure is essential for diagnosing voice disorders and monitoring treatment outcomes in voice therapy.
Usage
Usage note: Often abbreviated as 'strobes' in clinical notes, but the full term should be used in formal reports.
In Context
- "The videostroboscopy revealed incomplete glottal closure consistent with vocal fold paralysis." — Voice evaluation report
- "Pre- and post-treatment videostroboscopy demonstrated improved mucosal wave amplitude following voice therapy." — Treatment outcome documentation
