title: Vocal fold paralysis following carotid endarterectomy.
abstract: Injury to the vagus nerve or one of its branches during carotid endarterectomy (CEA) can result in vocal fold paralysis (VFP). This study assessed prospectively 73 patients undergoing CEA. A total of 76 procedures were performed in these patients over a one-year period. All patients underwent pre-operative and post-operative assessment of vocal fold mobility by indirect laryngoscopy and/or flexible nasendoscopy. All patients had normal vocal fold mobility pre-operatively. Eight patients (10 per cent) complained of hoarseness after surgery and in three patients (four per cent) examination confirmed an ipsilateral VFP. This persists in all three patients at six-month follow-up. Vocal fold assessment is important in patients undergoing CEA, particularly when performing second side surgery. We recommend that patients should be informed of the risk of VFP following CEA when obtaining consent.
