Larynx Anatomy on Ultrasound: True vs False Vocal Cords & How to Differentiate Them!

Ultrasound of the Larynx: Normal Anatomy and true vs false Vocal Cord Differentiation High-frequency ultrasound (7–15 MHz linear probe) effectively visualizes the larynx despite its cartilaginous framework and air-filled lumen. The thyroid and cricoid cartilages appear hypoechoic, with the cricoid being more uniform. The true vocal cords (TVCs) are thin, string-like, and hypoechoic, positioned medially and inferiorly, showing active movement during phonation and respiration—abducting in inspiration and adducting in expiration. In contrast, the false vocal cords (FVCs) are bulkier, hyperechoic, and superiorly located, with minimal movement. The epiglottis appears as a curved hypoechoic structure, and the arytenoid cartilages are small and hypoechoic. Ultrasound in transverse and longitudinal planes, with phonation tests, aids in detecting vocal cord paralysis, laryngeal masses, and airway obstruction. This non-invasive modality is particularly useful when laryngoscopy is difficult. #Ultrasound #Larynx #VocalCords #TrueVsFalseCords #Radiology #Sonography #LaryngealImaging
