AbstractThe patient was a 64-year-old woman with no history of laryngeal disorders. She underwent video-assisted right lower lobectomy and node dissection for lung cancer. Using a stylet while the patient was under general anesthesia, tracheal intubation with a 35-French gauge left-sided double-lumen endobronchial tube was successfully performed on the first attempt. The patient developed slight hoarseness on postoperative day 1, and we initially suspected recurrent laryngeal nerve paralysis caused by the surgery, which we elected to treat conservatively. However, because her hoarseness had not improved 4 months after surgery, we evaluated her vocal cords using laryngoscopy. This revealed severe dysfunction of the right vocal cord and arytenoid dislocation, which we treated through reduction using a balloon catheter. By 6 months, the patient's vocal cord mobility had improved. Arytenoid dislocation is a rare complication, but should be suspected when patients have right vocal fold paralysis after lung cancer surgery.
