Transcutaneous Laryngeal Ultrasonography: Technical Performance and Interpretation

Abstract

Vocal cord ultrasound (VCUS) has been shown accurate in demonstrating vocal cord paralysis with a sensitivity of 93–100 % and specificity ranging from 97 to 100 % when performed by surgeons. Although flexible laryngoscopy (FL) is considered the gold standard for vocal cord mobility evaluation, laryngeal ultrasonography can substitute FL in most patients requiring preoperative vocal cord function evaluation as long as the vocal folds can be well visualized on cervical ultrasound.
