This procedure is done to precisely remove lesions on the vocal cords.  Typical lesions include vocal cord nodules, polyps, blood clots, swelling, and tumors.  A direct laryngoscopy is performed, and a microscope is used to finely dissect off lesions from the vocal cord while trying to preserve vocal cord anatomy and function.  Sometimes, medications like steroids or dissolvable materials can be injected in or around the vocal cords to improve voice function.
