Some infants suffering from vocal cord paresis caused by the compression of cervical tumors such as cystic lymphangioma and congenital anomalies may manifest respiratory distress. Less-invasive examinations should be selected for the diagnosis of young patients in a poor general condition. Vocal cord paresis is generally diagnosed by laryngo-fiberscopy. Ultrasonography, which is another useful tool for the diagnosis of vocal cord paresis, can demonstrate the mobility of the vocal cord noninvasively. Observation of the vocal cords by ultrasonographic examination requires a certain level of technical skill. Despite this disadvantage, ultrasonography appears to be useful for the diagnosis of vocal cord paresis in infants in a poor general condition.
