Chronic laryngitis can be caused by a number of things including bronchitis that won't go away, smoking, or acid reflux disease. Continuous and strained use of the vocal cords is another cause, as is drinking alcohol in excess. Additionally, airborne irritants, allergens, chemical fumes, or even cancer and infections can be a root cause of chronic laryngitis.

Dr. Anthony Komaroff answered:
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 Parkinson's) 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.
