Reports on acquired traumatic laryngomalacia appear only rarely in the literature. We report a case of a 47-year-old patient with breathlessness after a transcervical approach to the spine during general anesthesia with intubation. Laryngostroboscopy revealed a smooth and, during inspiration, retroflexed epiglottis at the posterior pharyngeal wall. Additionally, dynamic magnetic resonance imaging for the first time showed hypermobility of the upper edge of the epiglottis. After partial laser epiglottectomy, the patient's complaints disappeared.
