Types of Voice Disorders
Voice disorders are medical conditions affecting the production of speech. These include:

  • Chorditis
The inflammation of vocal cords (vocal folds) usually as a result of voice abuse but sometimes because of cancer.
  • Vocal fold nodules
It is a mass of tissue that grows on the vocal folds (vocal cords). Typically, this mass will appear on the junction of the anterior and middle two-thirds of the vocal fold, where contact is most forceful.
  • Vocal fold cysts
Vocal fold cysts are collections of fluid in sac-like formations on the vocal folds.
  • Vocal cord paresis(paralysis)
It is weakness of one or both vocal folds. Symptoms of paresis include hoarseness; vocal fatigue; mild to severe reduction in vocal volume; pain in the throat when speaking; shortness of breath; aspiration (food or liquids going down the trachea) with frequent resultant coughing, and in extreme cases may cause death.
  • Reinke's edema
It, also known as polypoid degeneration, is the swelling of the vocal folds due to fluid collection (edema).
  • Spasmodic dysphonia
It is a voice disorder characterized by involuntary movements of one or more muscles of the larynx (vocal folds or voice box) during speech.
  • Foreign accent syndrome
It is a rare medical condition involving speech production that usually occurs as a side effect of severe brain injury, such as a stroke or head trauma.
  • Bogart–Bacall syndrome
It is a vocal misuse disorder. People most commonly afflicted are those who speak in a low-pitched voice, particularly if they have poor breath and vocal control.
  • Laryngeal papillomatosis
It is a rare medical condition (2 per 100,000 adults and 4.5 per 100,000 children), caused by a HPV infection of the throat.
  • Puberphonia
It is the persistence of adolescent voice even after puberty.
