RationaleEpiglottic retroversion is the abnormal movement of the epiglottis to the rima glottis, resulting in blockage of inspiratory airflow. Acute upper airway obstruction caused by epiglottic retroversion can lead to sudden respiratory failure. Epiglottic retroversion has occasionally been reported in horses and dogs; however it is extremely rare in humans. Herein, we report a case of epiglottic retroversion causing recurrent upper airway obstruction in human.Patient ConcernsWe present the case of a 74-year-old man who was diagnosed with epiglottic retroversion without evidence of epiglottis. The patient presented with recurrent episodes of abnormal breathing sounds and dyspnea. Inspiratory stridor was evident whenever the patient experienced dyspnea.DiagnosisEpiglottic retroversion was diagnosed as the cause of upper airway obstruction using fiber-optic bronchoscopy.InterventionsThe patient underwent tracheostomy to prevent acute respiratory failure because the recurrent episodes of stridor and dyspnea did not improve.OutcomesThe episodic dyspnea and oxygen desaturation did not relapse after tracheostomy and he could be discharged home.LessonsThis case highlights the importance of considering epiglottic retroversion as a cause of acute upper airway obstruction.Copyright © 2024 the Author(s).
