Vocal cord lesions are one of the most common causes of voice problems. They include vocal nodules and vocal polyps, which are abnormal growths on your vocal cords.

  1. Vocal nodules are thickened areas that typically occur on both vocal folds, and are often known as “singer’s nodules” or “calluses of the vocal fold”
  2. Vocal polyps are growths that usually present on only one vocal fold, and may look like a swollen bump or blister
  1. Usually caused by repetitive vocal cord trauma (e.g. frequent shouting)
  2. Reflux of stomach acid into the larynx
  3. Long-time exposure to irritants (e.g. cigarette smoke, alcohol)
  1. Hoarse and rough voice
  2. Lowered pitch
  3. Breathy voice
  4. Voice breaking
  5. Frequent throat-clearing
  6. Vocal fatigue
  1. May pass a nasoendoscope down through the nose to the voice box (under local anaesthesia)
  2. A more detailed examination may require the use of a videostroboscopy
    1. A telescope tube with light is passed through the mouth to view the voice box (under anaesthesia)
  3. History of voice use and other medical conditions will be evaluated as well

Treatment greatly depends on what caused the vocal nodules or polyps, their size and other medical problems you may have that affects the voice. You may have to treat your reflux, nasal allergies and thyroid problems before the vocal nodules will go away. You may have to stop smoking and you may have to see a vocal therapist. Or you may simply require a period of voice rest.

Only if all these fail, will vocal surgery be considered.
