Value of ultrasonography in diagnosis of pediatric vocal fold paralysis

Unilateral Vocal Fold Paralysis After Congenital Cardiothoracic Surgery: A Meta-analysis

“…The mean patient age was 21.4 months. Wang et al 40 reported the usefulness of laryngeal ultrasound for vocal fold assessment. They showed maximum glottic angle and vocal fold-arytenoid angle to be quantitative ultrasonographic indicators of vocal fold immobility among 45 children of median age 4 years and 6 months (range 9 months-13 years).…”

The importance of sonographic landmarks by transcutaneous laryngeal ultrasonography in post-thyroidectomy vocal cord assessment

“…AR cartilages were seen as a paired oval hyperechoic structure underneath the TC and FC. 13,14 Both passive (ie, quiet spontaneous breathing) and active (phonation with a sustained vowel ''aa'') movement of the VCs were assessed. After TLUSG, DL was performed by a different endoscopist who was unaware of the patient's voice quality and the TLUSG findings.…”

“…The 3 most commonly described sonographic landmarks are the false cords (FC), true cords (TC), and arytenoids (AR). 13,14 However, it remains unclear what their relative importance is in VC assessment. Furthermore, it is unknown whether identifying more landmarks during TLUSG would improve the diagnostic sensitivity, specificity, and accuracy during VC assessment.…”

“…Elle n'est indiquée que pour analyser le contenu de masses cervicofaciales et, pour certaines équipes, la dynamique glottique à la recherche d'une paralysie au cas très rare où la laryngofibroscopie ne serait pas possible ou non contributive par artéfacts (sécrétions ou hémorragie par exemple) [3].…”
