## Overview Laryngeal function refers to the ability of the larynx to open fully during exercise. The sternothyroideus and other extrinsic muscles help position the larynx. Dysfunction contributes to dynamic airway collapse, respiratory noise, and reduced exercise tolerance. It is assessed by resting and exercising endoscopy. ## Causes Neuromuscular dysfunction, inflammation, or anatomic abnormalities affecting laryngeal position and stability. ## Diagnosis Exercising endoscopy is the gold standard. Resting endoscopy may show reduced arytenoid movement. ## Treatment Depends on the specific abnormality (for example, tie-forward for dorsal displacement of the soft palate, or prosthetic laryngoplasty for recurrent laryngeal neuropathy). ## Recovery and Prognosis Variable by diagnosis and chosen treatment. ## Prevention Management of airway inflammation and appropriate conditioning.
