“…This finding correlates to previous reports demonstrating reliable stroboscopic evaluation of subepithelial lesions without benefit from HSI. 10 Though vocal fold polyps were reliably diagnosed using HSI in the present study, the magnitude of correlation was greater using stroboscopy, and the data do not support the indication of HSI to improve the diagnostic capacity of polyps. The present study did identify presbyphonia as a clinical pathology in which the diagnostic concordance of HSI was greater than stroboscopy.…”

“…Previous investigations have examined the auditory characteristics that are more indicated for HSI examination, mainly those with moderate-to-severe dysphonia. 10 HSI demonstrated significant and meaningful interrater correlations for specific diagnostic categories, including vocal fold polyps and presbyphonia. Expert raters were also able to reliably identify normal laryngeal examinations with HSI.…”

“…11 Patel et al found HSI a useful adjunct to stroboscopy specifically with neuromuscular etiologies of dysphonia; however, it is unclear as to what extent clinical diagnosis and treatment would differ without HSI. 10 Mortensen and Woo described a single case report in which HSI did change the clinical course of a dysphonia patient. Using HSI, a new finding of unilateral mucosal wave asymmetry was seen which was not found on stroboscopy.…”

“…Current clinical recommendations include offering patients HSI examination as a clinical adjunctive analytic tool, 9 specifically with severely dysphonic voices. 10 However, there is currently little information guiding the specific clinical scenarios or indications, in which HSI may offer clinical benefit above the standard of laryngovideostroboscopy. It is therefore our objective to perform an exploratory study to identify in which specific laryngeal pathologic states HSI may improve the diagnostic yield above the current standard of videostroboscopy.…”

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.

“…High speed laryngeal imaging has evolved as a method of laryngeal visualization that overcomes many of the limitations of videostroboscopy [30][31][32]. It has been proposed as a useful diagnostic tool for vocal fold paresis [33] and a method for automatic diagnosis of vocal fold paresis has been developed by use of image-analysis technology based on high-speed imaging [34].…”

Unilateral vocal fold immobility (UFVI) is a highly variable clinical entity that may be neurogenic or mechanical in origin. Patients with UVFI have varying degrees of voice, swallowing, and airway disturbance. The patient should be carefully evaluated, including thorough history, head, neck, and neurologic examination, and laryngoscopy, to determine the etiology of UFVI and the current level of laryngeal function. If the etiology cannot be determined, cross sectional imaging of the skull base through the mediastinum is recommended to evaluate the underlying cause. Laryngeal electromyography is most useful for predicting poor functional recovery and may affect the decision to proceed with early definitive surgical management. Formal swallowing testing is indicated for patients with dysphagia to identify aspiration.

Laryngeal examination in thyroid and parathyroid surgery: An American Head and Neck Society consensus statement

et al. 2016

View full text Add to dashboard Cite

This American Head and Neck Society (AHNS) consensus statement discusses the techniques of laryngeal examination for patients undergoing thyroidectomy and parathyroidectomy. It is intended to help guide all clinicians who diagnose or manage adult patients with thyroid disease for whom surgery is indicated, contemplated, or has been performed. This consensus statement concludes that flexible transnasal laryngoscopy is the optimal laryngeal examination technique, with other techniques including laryngeal ultrasound and stroboscopy being useful in selected scenarios. © 2016 Wiley Periodicals, Inc.
