Aphonia generally happenes due to the problems with the voice box (called the larynx). However, there can be other causes, including:

Conditions that affect the vocal cords or airway, this may include injury, swelling, or disease, like:

  • Laryngitis that is caused by a viral, bacterial, or fungal infection
  • Vocal abuse—yelling or talking excessively
  • Exposure to airborne irritants, like smoke or air pollution
  • Acid reflux from gastroesophageal reflux disease (GERD)

Diagnosis of Aphonia

You will be asked about your symptoms and medical history. A physical exam will be done.

The cause of your symptoms may not be obvious. You may be referred to an ENT specialist. This doctor may use an instrument called a laryngoscope to check your vocal cords. Other tests may also be done to evaluate your voice function.
