Vocal cord disorders can affect your voice or your ability to talk. These disorders affect the vocal cords. The vocal cords (also called vocal folds) are two bands of smooth muscle tissue found in the voice box (larynx). The voice box is set in the neck at the top of the windpipe (trachea).
The vocal cords vibrate as air passes through the cords from the lungs to make the sound of your voice. The sound is then sent through the throat, nose, and mouth. The sound of each person's voice is determined by the size and shape of the vocal cords. It's also determined by the size and shape of the throat, nose, and mouth.
Some of the more common vocal cord disorders include:

Laryngitis
|
Laryngitis causes a raspy or hoarse voice due to swelling (inflammation) of the vocal cords. It can be caused by using your voice too much, infections, breathing in irritants, or GERD (gastroesophageal reflux).

Vocal nodules
|
These are noncancer growths on the vocal cords caused by vocal abuse. Vocal nodules are often a problem for professional singers. The nodules are small and callus-like. They most often grow in pairs (one on each cord). The nodules most often form on parts of the vocal cords that get the most pressure when the cords come together and vibrate. Vocal nodules cause the voice to be hoarse, low, and breathy.

Vocal polyps
|
A vocal polyp is a soft, noncancer growth. It is a lot like a blister. Vocal polyps cause the voice to be hoarse, low, and breathy.

Vocal cord paralysis
|
This may happen when one or both vocal cords doesn’t open or close correctly. It is a common disorder. It can range from fairly mild to life-threatening. When one or both vocal cords are paralyzed, food or liquids can slip into the trachea and lungs. A person may have trouble swallowing and coughing. This condition may be caused by:
- Head, neck, or chest injury.
- Intubation (breathing tube placed for general anesthesia).
- Stroke.
- Tumor.
- Lung or thyroid cancer.
- Certain neurological disorders, such as multiple sclerosis or Parkinson's disease.
- Viral infection.
Treatment may include surgery and voice therapy. Sometimes no treatment is needed, and a person recovers on their own.
