Preoperative detection of vocal cord palsy is important in thyroid and parathyroid surgery. However, routine fiberoptic laryngoscopy may bring patients unnecessary discomfort. The aim of this study was to determine the feasibility of using surgeon-performed ultrasonography (US) as a screening tool for preoperative assessment of vocal cord movement.


In the first phase, patients had both laryngoscopic and US examination before surgery. In the second phase, patients had US evaluation first. Those with abnormal vocal cord movement on US, with invisible cord movement, or presenting with significant vocal symptoms underwent laryngeal examination.


In all, 93 (82 %) of 114 patients had successful US evaluation of vocal cord movement during the first phase. Two of them had vocal cord paralysis. In the second phase, vocal cord movement could be evaluated by US in 349 (84 %) of 415 patients. Four patients with abnormal movement were confirmed to have vocal cord palsy by laryngoscopy. None of 46 symptomatic patients with normal movement on US had vocal cord palsy. One other patient whose cord movement could not be seen by US had vocal cord palsy on laryngoscopic examination.


Surgeon-performed US appears to be a relatively accurate method for assessing vocal cord movement in the preoperative setting. It can be used to select patients to undergo laryngoscopic examination before thyroidectomy and parathyroidectomy.
