Abstract
Two cases of vocal fold cyst, which occupy the whole part of the intermembranous portion, were reported. The treatment for vocal fold cyst is a perfect extraction under the micro-surgery, the other side we sometimes experience difficult cases; impossibility of complete extractions or happening post operative troubles in spite of completes extraction. It was examined about the way of coping with such difficult cases. Since the risk that troubles happen is high rate in case of large cyst the surgeon is required more careful coping with vocal fold cysts.
