AbstractVagus nerve injury may complicate carotid endarterectomy (CEA). The recurrent laryngeal nerve (RLN) branches from the vagus nerve, innervating the ipsilateral vocal cord. Vagus nerve injury can cause vocal cord dysfunction. Intraoperative vocal cord monitoring can detect vagus nerve injury during CEA. A patient with distorted neck anatomy from radiotherapy to treat oropharyngeal cancer and resultant right vocal cord paralysis required left CEA. Anticipating difficult neck dissection risking vagus nerve damage with associate RLN malfunction, we added vocal cord electromyography (EMG) to routine CEA electroencephalography (EEG). We recommend vocal cord EMG in anatomically complex CEA to avoid vagus nerve injury.
