    Abstract:
    We encountered left recurrent nerve palsy in four patients who had undergone surgery unrelated to the course of the vagus nerve or recurrent nerve, during which they had received endotracheal anesthesia. They were intubated without difficulty and underwent surgery without trouble, but postoperatively they all complained of hoarseness. We used a disposable ENTRASOFT endotracheal tube with high volume, low-pressure cuff in three patients and a disposable PORTEX endotracheal tube with low volume, standard cuff in one patient. In three patients recurrent nerve palsy healed completely within two months after the operation, and one patient was recovering from the palsy on the twentieth day after the operation. We believe that the most plausible explanation of recurrent nerve palsy is the excessive pressure from the inflated endotracheal tube cuff on the intralaryngeal course of the anterior branch of the recurrent nerve. Monitoring cuff pressure is most important to prevent recurrent nerve palsy after endotracheal intubation.
