Laryngeal hypersensitivity in chronic cough.
Patients with chronic cough often report symptoms arising in the throat, in response to non-specific stimuli. Accordingly, the concept of a 'hypersensitivity' of the larynx in chronic cough has evolved over the past ten years. Patients with cough and laryngeal hypersensitivity frequently report features that overlap other laryngeal dysfunction syndromes, including a tendency for the vocal cords to inappropriately adduct. The mechanisms underlying laryngeal hypersensitivity in chronic cough are currently unclear, however recent studies provide new clinical and physiological techniques to aid detection and monitoring of laryngeal hypersensitivity. This review provides an overview of the current state of knowledge in this field.
