What Causes Laryngitis?

Stroke

The larynx is a complex structure made of numerous different muscles and tissues that serves several functions. These functions are controlled by the nerves and central nervous system via impulses sent to and from the brain. A stroke is an event where a part of the brain becomes deprived of its blood supply and becomes damaged. One of the most common symptoms of a stroke is the paralyzation or functional impairment of muscles around the body. When the part of the brain that controls the movement and actions of the laryngeal components becomes damaged due to stroke-precipitated ischemia, the patient can develop laryngitis. When the larynx is not functioning properly, it cannot protect the airways and prevent the development of infections in the sinuses, lungs, and throat that can cause laryngitis. The impaired larynx is also unable to prevent the patient's airways from general irritants that can produce inflammation in the vocal folds or laryngitis.
