What is Hoarseness (Dysphonia)
Dysphonia is an abnormal voice. It’s also called hoarseness. There are many causes of dysphonia. These are listed below. Voice changes can happen suddenly or slowly over time. A voice that is hoarse, raspy, dry, strained, weak, or breathy can be described as grave. Voice breaks can occur when the voice stops completely or cuts out. The patient may experience pitch changes that are either higher or lower. For a short time, the patient might experience a loss of their voice. The patient may complain of difficulty speaking or singing, and sometimes have trouble projecting their voice. Dysphonia most often results from an abnormality in the vocal cords (also called vocal folds), but other causes can include problems with airflow or structures of the throat that are near the vocal cords.

Causes of Hoarseness (Dysphonia)
There are many causes of dysphonia. These are listed below in common categories.
- Laryngitis: A swelling of the vocal cords due to overuse of the voice, or a viral infection
- Allergies: Cough, post-nasal drip, and sneezing cause swelling of the vocal cords.

- Vocal chord polyps: A small growth on the vocal chord that looks like a blister due to overuse or injury from yelling
- Vocal chord cyst: A small growth that forms on the vocal cord and is usually filled with mucous. This causes a raspy and rough voice
- Vocal chord papilloma: A small wart on the vocal cords caused by exposure to a particular virus called the human papillomavirus
Scarring of vocal cords:
