Indiana ENT Specialties with CENTA


Problems with voice usually present as hoarseness. Hoarseness occurs when a person is having difficulty producing sound in order to speak. Sometimes, the person is able to speak, but the pitch or tone of the voice has changed. It may be weak, husky, breathy or scratchy. Hoarseness is usually caused by a problem of the vocal cords. Hoarseness that lingers for weeks or months may be caused by a variety of problems—some minor, some serious.

Causes of Hoarseness

Voice problems often present as hoarseness. Hoarseness has many causes:

  • Nodules or polyps growing on the vocal cords
  • Night-time reflux (Laryngopharyngeal reflux or LPR) which causes vocal cord swelling
  • Cancerous or pre-cancerous lesions
  • Muscle Tension Dysphonia
  • Spastic Dysphonia

A proper history and direct exam of the voice box by a knowledgeable ENT doctor is key to accurate diagnosis and treatment. A vast majority of hoarseness, especially in non-smokers, is not cancer-related.
