What is laryngeal hypersensitivity?

Hypersensitivity of the larynx can be both a cause and a symptom of a variety of laryngeal disorders, including chronic cough, paradoxical vocal fold motion disorder (PVFM) or vocal cord dysfunction, globus sensation, and some instances of muscle tension dysphonia.  Common triggers are found in many of these sensory disorder syndromes.
