“…In the context of thyroid surgery, which is performed in 80% of women versus 20% of men, the limitation observed on the male population would concern only a small number of cases. Furthermore, as recently proposed by Woo et al, lateral acquisitions and dedicated quantification could be developed for these subjects …”

“…In a larger cohort, Wang et al reported that vocal fold motion using US could be assessed in 87% of patients, and that it was less observable in male subjects and in older patients . Recently, US has been proposed in surgery research to assess vocal fold motion during breathing at rest and detect recurrent nerve paralysis after thyroid surgery . It was proposed to estimate the symmetry of the laryngeal tract in abduction and adduction, and diagnosis of recurrent nerve paralysis was based on the visual impression of vocal fold immobility.…”

“…Most of these studies reported visual criteria to assess the vocal fold motion. Current debates deal with the choice of appropriate landmarks (true vocal folds, false vocal folds, or arytenoids); the choice of the acquisition plane (axial or lateral view); the choice of observation condition (free breathing, phonation, or Valsalva maneuver); and the development of the method in multiple institutions using various US scanners …”

Vocal fold motion was analyzed during free breathing using two-dimensional dynamic ultrasound imaging. Two cadavers were first analyzed to define easily identifiable landmarks. Motion of the laryngeal tract was then analyzed in an axial plane. Left and right arytenoids and thyroid cartilage were defined on images corresponding to abduction and adduction of the laryngeal tract. Associated area measurements were established for 50 healthy subjects. All area indices were significantly larger during abduction than adduction. Symmetry of motion was established by comparing each hemi-larynx, and mobility fractions were defined. Normal values of laryngeal motion during free breathing were thus established.

“…Woo et al 1 describe their experience with lateral approach for laryngeal evaluation and they have concluded 100% sensitivity and 99% specificity for evaluation of vocal cord paralysis. They have compared the anterior and lateral approach for laryngeal evaluation with ultrasound, and Carneiro-Pla et al 2 report the use of surgeon-performed vocal cord ultrasound and reduced the incidence of flexible laryngoscopy.…”

Laryngeal ultrasound (US) is becoming widely accepted for assessing true vocal fold immobility (TVFI), a potential complication of laryngeal and thyroid surgery. The objective of this project is to perform a systematic review and meta‐analysis of pooled evidence surrounding laryngeal US as a modality for diagnosing TVFI in adults at risk for the condition in comparison to laryngoscopy as a gold standard. Medical subject heading terms were used to search MEDLINE, Embase, Google Scholar, Web of Science, and the Cochrane Library for relevant citations from January 1, 2000, to June 30, 2020. Studies were included if they involved patients 16 years and older, where laryngeal US was compared to laryngoscopy for TVFI. Studies were excluded if there were insufficient data to compute a sensitivity/specificity table after attempting to contact the authors. Case reports, and case series were also excluded. The initial search returned 1357 citations. Of these, 109 were selected for review utilizing the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines. Thirty citations describing 6033 patients were included in the final meta‐analysis. A bivariate random effects meta‐analysis was performed, revealing a pooled sensitivity for laryngeal US of 0.95 (95% confidence interval [CI] 0.88–0.98), a specificity of 0.99 (95% CI 0.97–0.99), and a diagnostic odds ratio of 1328.2 (95% CI 294.0–5996.5). The area under the curve of the hierarchical summary receiver operating characteristic curve was 0.99 (95% CI 0.98–1.00). Laryngeal US demonstrates high sensitivity and specificity for detecting VFI in the hands of clinicians directly providing care to patients.
