“…Sataloff et al [9] analysed 1,876 laryngostroboscopic procedures performed over a 5-year period in ''professional voice users'' with dysphonia and known diagnosis. They found that in 29 % of patients the stroboscopy not only confirmed the existing diagnosis but also supplied additional diagnostic information, while in 18 % of patients the stroboscopy indicated that the existing diagnosis was incorrect.…”

The aim of this study is to evaluate the effectiveness of the laryngostroboscopy for monitoring the evolution of patients with functional dysphonia before and after the logopedic vocal treatment. We performed a prospective observational study of 65 dysphonic patients diagnosed of functional dysphonia, where we analyzed four stroboscopic parameters (glottal closure, vocal fold vibration, mucosal wave and phase symmetry) by a protocol based on systematic subjective evaluation of the stroboscopic images before and after the rehabilitator treatment; and the results were stratified according to the clinical course. All patients, before the treatment, had some abnormality in at least one of the four analyzed aspects. After the vocal treatment, we found improvement of the four parameters in different degrees, and we just found a statistically significant relationship between the evolution of the glottal closure and the clinical course. We believe that the laryngostroboscopy, systematized through a protocol, is a useful technique for the diagnosis of functional abnormalities in patients with functional dysphonia but it is not a very useful technique for evaluating the results after the rehabilitator treatment, as there is not a statistically significant relationship between clinical course and the change in the most stroboscopic parameters, so it shouldn't be the only technique used for these proposes.

“…The clinical utility of stroboscopy was established with initial studies of clinical utility 4 and diagnostic concordance. 5 Since that time, stroboscopy has been confirmed to be the recommended examination modality in the specialized evaluation of the dysphonic patient. 6 Notwithstanding, laryngeal stroboscopy contains many inherent weaknesses, including a dependence on regular phonation and minimum requisite phonation time of 2 seconds.…”

Summary: Objective. Although high-speed imaging (HSI) has been identified as a valuable tool in phonatory biomechanics research, to date, there have only been a selected number of reports investigating the clinical utility of HSI. We aim to elucidate the role of HSI in the diagnosis of the dysphonic patient. Methods. The video files from 28 consecutive dysphonic patients with concurrently acquired videostroboscopy and HSI were retrospectively collected. Stroboscopy video files were edited to include vibratory motion only. Videos were then anonymously and randomly presented to four academic laryngologists. Experts were asked to assign a single best diagnosis for each video file. Assigned diagnoses were then compared with treatment diagnoses conferred based on medical history, phonatory evaluation, laryngeal examination, and response to treatment. Results. Interrater analysis for the four laryngologists demonstrated significant and meaningful correlations for the diagnoses of polyps, cysts, nodules, and normal examination using stroboscopy (kappa > 0.40, P < 0.001). The experts demonstrated significant and meaningful correlations for the diagnoses of polyps, presbyphonia, and normal examination using HSI (kappa > 0.40, P < 0.001). Combined intrarater analysis performed by comparing single rater's diagnosis for single patient across both modalities resulted in poor correlation without statistical significance (kappa ¼ 0.30, P ¼ 0.07). Both stroboscopy-and HSI-assigned diagnoses matched the treatment diagnoses at equal predicted frequencies (32.3%), as demonstrated through multivariate logistic regression analysis (P < 0.001). Conclusion. Overall, HSI did not improve the diagnostic accuracy above stroboscopy alone. Although specific laryngeal states such as presbyphonia may be better diagnosed with HSI, further studies are required to define HSI's precise role in the clinical setting.
