Vocal Cord Paresis/Paralysis

Results from abnormal nerve input to the muscles of the voice box (larynx.)  Paresis is partial interruption resulting in weak or abnormal motion of the muscles.  Paralysis is a total interruption of the nerve impulse.  Both result in voice changes including hoarseness or a “breathy” voice.  Vocal cord paralysis can also result in airway problems including shortness of breath and noisy breathing. 

Both of these abnormalities can be seen using flexible fiberoptic laryngoscopy, a procedure performed in the office using just a topical anesthetic.
