Bilateral adductor vocal cord paresis following endotracheal intubation for general anaesthesia.

Recurrent laryngeal nerve palsy is a rare complication of endotracheal intubation. We report a case of bilateral vocal cord palsy following endotracheal intubation for general anaesthesia. The clinical picture was of hoarseness and aspiration suggestingpartialparesis, as complete bilateral recurrent laryngeal nerve palsy usually causes acute airway obstruction due to unopposed vocal cord adduction. Compression of the anterior branch of the recurrent laryngeal nerve between the cuff of the endotracheal tube and the posterior part of the thyroid cartilage was the likely mechanism. Ensuring that the cuff of the endotracheal tube is distal to the cricoid cartilage and that the pressure in the cuff is kept to the minimum required to prevent a gas leak should prevent this complication.
