Vocal cord dysfunction (VCD) is a condition affecting the vocal cords. [1] It is characterized by abnormal closure of the vocal folds, which can result in significant difficulties and distress during breathing , particularly during inhalation .
The site for the cordotomy is determined at the preoperative examination. If any one of the vocal fold seems to have a slightest degree of motion, then cordotomy is performed on the other one.
