A Large Vocal Fold Polyp Causing Dyspnea

Laryngeal polyps are common, but some hospitals have reported that a giant vocal fold polyp could cause dyspnea. We encountered a giant vocal fold polyp with dyspnea. Under general anesthesia, laryngomicrosurgery successfully improved the symptoms of the dyspnea. In this case, stenosis of the posterior glottis (considered to be the respiratory glottis) due to a giant vocal fold polyp was thought to be the cause of the preoperative dyspnea.
