There are many options to improve the voice in the setting of a unilateral vocal cord paralysis. The paralysis causes a diminished ability for the vocal cords to close leading to air escape and therefore vocal hoarseness. There is no current way to return vocal cord function to a paralyzed vocal cord, however, there are approaches that allow the vocal cord to be medialized so that the functioning vocal cord can approximate the nonfunctional cord and create closure and then resultant improvement in vocal strength and reduced vocal hoarseness. There are nuances obviously regarding the specific case and those are determined by a laryngologic exam. I would recommend seeing a Laryngologist with expertise in these techniques for a full evaluation and to discuss your specific options.
