Airway Obstruction Caused by Mucinous Material Adherent to the Epiglottis in a Patient with a Progressive Neurological Disorder: An Unusual Case of a Condition Mimicking Acquired Laryngomalacia

We herein report the successful management of a condition mimicking acquired laryngomalacia using conservative methods in an elderly man with a progressive neurological disorder. The patient developed stridor and was transferred to the intensive-care unit. Flexible laryngoscopy revealed a collapsed epiglottis during inspiration, as seen in acquired laryngomalacia, with mucinous material firmly adhered to the epiglottis. The stridor resolved after the removal of this material. Pathology revealed keratinized material, suggesting a collection of sputum or epithelial tissue. Thus, flexible laryngoscopy can differentiate the cause of airway obstruction and avoid unnecessary endotracheal intubation in patients with neurological disorders.
