AbstractA 41-year-old man of ASA physical status class I was scheduled to receive the video-assisted thoracoscopic T2 sympathectomy for hyperhidrosis palmaris. The elective surgery was performed smoothly under general anesthesia with endotracheal intubation. However, the patient complained of hoarseness in the postoperative period. A stroboscopic examination showed that the left vocal cord remained stationary in the paramedian position, signifying left vocal cord paralysis. In the case, we believed it was most likely that endotracheal intubation might be responsible for the unilateral vocal cord paralysis. The possible cause was that during placement or thereafter during positioning, the endotracheal tube was malposed or slipped upward, rendering its inflated cuff to rest against the vocal cords. Another reason was that the cuff which was over inflated made the vocal cords under constant pressure. Both conditions may cause damage to the anterior branch of the recurrent laryngeal nerve. We also discussed the general management and prophylaxis for the unilateral vocal cord paralysis.
