[Bilateral vocal cords paresis following iodine therapy].

We present a case of a 33 year old man who underwent a thyroidectomy due to papillary thyroid carcinoma, with a reversible paresis of both vocal cords after radioiodine therapy. The patient had no previous lesion in laryngeal nerves. Paralysis of the vocal cords is a rare complication of the 131I administration and generally occurs more frequently when there is already some type of lesion in the recurrent laryngeal nerves. The paper reviews the literature on this type of complications.
