High-speed glottography (HGG) offers a more reliable diagnostic tool than videostroboscopy (VS) for assessing vocal fold vibrations in patients with dysphonia, showing fewer failures and better rater agreement.

Area of Science:

  • Laryngology
  • Speech Pathology
  • Medical Imaging

Background:

  • Dysphonia diagnosis relies on evaluating vocal fold vibratory patterns.
  • Videostroboscopy (VS) and high-speed glottography (HGG) are methods used for this assessment.
  • Comparative diagnostic value of VS and HGG requires further investigation.

Purpose of the Study:

  • To compare the diagnostic accuracy of videostroboscopy (VS) and high-speed glottography (HGG).
  • To evaluate the reliability of both methods in assessing vocal fold vibratory movements in dysphonic patients.

Main Methods:

  • A randomized, prospective study involving 162 patients with dysphonia.
  • Indirect laryngoscopy performed using both VS and HGG, with 324 films analyzed.
  • Standardized protocol and established criteria used by two laryngologists to classify vocal fold vibratory movement.

Main Results:

  • "Not assessable" ratings were significantly more frequent with VS than HGG (P < .001).
  • HGG demonstrated fewer methodologic failures and a shorter investigation time.
  • Inter-rater agreement was higher for HGG (54%) compared to VS (42%), though both indicated low diagnostic accordance.

Conclusions:

  • Perceptive evaluations of vocal fold vibratory movements exhibit higher variability than anticipated, irrespective of the method used.
  • The findings underscore the necessity for objective methods in analyzing vocal fold vibratory dynamics.
  • Real-time imaging via HGG is crucial for accurate assessment of vocal fold vibratory movements.
