Disorders of the Voice

Established in 1992, the Laboratory has amassed one of the world’s largest medical databases for voice, with over 12,000 cases. It is a vast resource of knowledge and experience the staff consults when diagnosing problems and planning treatment.

The Laboratory treats both adults and children voice-related problems, related to a wide range of causes, including but not limited to:

  • Neurological disorders, including nerve damage, multiple sclerosis and Parkinson's
  • Non-neurological disorders including trauma to the larynx and cancer
  • Vocal hyperfunction – problems caused in the course of using the voice

Symptoms generally include hoarseness, a weak or “breathy” voice, difficulty projecting, voice loss and when the voice is easily fatigued – deteriorating rapidly with use. Such symptoms manifest themselves through a range of specific voice disorders, including:

  • Irritable larynx syndrome
  • Chronic cough
  • Vocal cord dysfunction
  • Stridor – airway narrowing
  • Lesions, cyst and nodules
  • Muscle tension dysphonia
  • Spasmodic dysphonia
  • Laryngospasm
