Overview

 

Dysphonia is a descriptive medical term meaning disorder (dys- ) of voice (-phonia). There are many causes of dysphonia. Fortunately more than half of people with voice complaints have a benign (non-cancerous) cause.




Causes

 
  • Inflammation of the larynx (voice box) over a short (acute) or long (chronic) period of time.
  • Lumps (nodules) on the vocal cords (eg singer’s nodules).
  • Underactive thyroid gland – hypothyroidism.
  • Trauma - any kind of trauma, including surgery, to the vocal cords will inevitably cause scarring and hence affect the vocal fold function. The risk of permanent voice change therefore needs to be discussed prior to surgery on the larynx.
  • Vocal cord paralysis – some other surgical operations including removal of the thyroid gland and heart or lung surgery can damage the nerves to the larynx causing either temporary or permanent vocal cord paralysis (palsy).
  • Reinke’s oedema of the larynx.
  • Psychological - voice changes are not uncommon when people are under stress either at work or at home. The voice may be lost suddenly, usually overnight or following a cold. It is important to identify and remove the underlying stress. Speech therapy is very useful for this cause.

he above conditions are commonly seen in ENT (ear, nose and throat) specialist clinics but there are many other relatively uncommon and rare diseases not mentioned here.

 



Symptoms

 People with dysphonia may present with hoarseness and a sore or dry throat. A singer may notice that he or she is no longer able to sing in the upper range. There may be other associated symptoms such as a continuous drip at the back of the throat (nasal catarrh) and heartburn.
