Vocal cord polyps are benign space-occupying lesions of the vocal cords, mainly appearing as polypoid protrusions on the surface of the free edge of the vocal cords, sometimes with a thin stalk, and sometimes with a broad base. In clinical practice, vocal cord polyps are primarily examined using a laryngoscope, and can also be assessed via CT and MRI. However, ultrasound is not used to examine vocal cord polyps, as ultrasound produces many artifacts and the neck’s muscles and soft tissues are very rich, preventing ultrasound from correctly or fully displaying the condition of the vocal cord polyps. In summary, ultrasound is not used clinically to examine vocal cord polyps.
