Hoarseness (Dysphonia) Explained

Hoarseness, also known as dysphonia, is a common problem that may have serious causes. A patient who has been hoarse for three weeks or more should be evaluated by an otolaryngologist.

Patients often attribute their hoarseness to a recent respiratory infection, although months may have passed and all other symptoms of the infection have long since disappeared. While respiratory viruses are one possible cause of chronic hoarseness, other causes may include: 

  • Carcinoma, typically a Squamous Cell variety
  • Acid reflux, or silent reflux – laryngopharyngeal reflux
  • Benign lesions, such as nodules, polyps, and cysts
  • Aging of the larynx (presbylaryngis)
  • Neuropathy, often from prolonged intubation, surgical trauma, malignancy
  • Tumors and arterial abnormalities of the chest, both of which can interfere with the course of the recurrent laryngeal nerve

The evaluation of a patient experiencing dysphonia begins with a fiber optic laryngoscopy, which may be coupled with videostroboscopy to capture how the vocal folds move and vibrate. A laryngeal electromyography (EMG), which is done in concert with a neurologist, may be performed. For this procedure, we use a fine electrode and insert it into the muscles of the larynx. From these recordings, our physicians are able to evaluate the health and strength of the muscles in the larynx.
