A:
Laryngitis is a condition that causes a loss of voice quality or volume. It can have a number of causes.
Lung problems (such as emphysema, asthma, pneumonia and Parkinsons) can lead to a weak voice. Swelling of the vocal cords from infection, overuse, or acid reflux can prevent the vocal cords from vibrating properly.
Other causes include:
- paralysis of one vocal cord
- noncancerous (benign) and cancerous (malignant) growths on the vocal cord
- scarring of the vocal cord
- narrowing of the airway above or below the vocal cords
- some neurologic disorders
When laryngitis lasts for more than 4 weeks, you should see an ear nose and throat doctor. The doctor will ask about your health history and do a complete exam of the head and neck, including a look at the vocal cords when they work.
If the cause is still unclear, you may have a video stroboscopy exam. This allows the doctor to watch the vocal cords move in slow motion.
