I was recently diagnosed with Bowed Vocal Cords. The next day I started a series of tests including the Iodine 123 trace indicating an over-active thyroid gland. Could the Hyperthyroid condition have effected my vocal cords and perhaps have caused the bowing?

While there may be differing causes of vocal cord atrophy, there is no known relationship between hyperthyroidism and presbylarynx, or "bowed" vocal cords.
Good luck to you!
