Aphonia Loss Of Voice
Loss of voice (also called aphonia) may take several different forms. You may have a partial loss of your voice and it may sound hoarse. Or, you may have complete loss of your voice and it may sound like a whisper. Loss of voice can come on slowly or quickly depending on the cause.
Aphonia is different from aphasia, which is a language disorder.

- Acid reflux (such as heartburn)
- Thickening of the vocal chords
- Nodules or polyps on the vocal chords
- Muscle tension dysphonia
- Damage to the nerves that affect how the larynx functions
- Laryngeal or thyroid cancer
- Removal of larynx due to cancer
- Breathing problems that affect the ability to speak
- Neurological disorders (such as myasthenia gravis, multiple sclerosis, Parkinson’s disease, amyotrophic lateral sclerosis)
