Asymptomatic giant epiglottic cyst causing an unexpectedly difficult airway: A case report

Abstract

Background: The presence of giant epiglottic cysts can lead to throat discomfort, foreign body sensation within the throat and respiratory distress. However, asymptomatic sufferers who remain undiagnosed may additionally face demanding situations in airway control during anesthesia emergencies. In intense instances, a tracheotomy may be required. Case presentation: A 61-year-old male, recognized with heel spur, underwent optionally available arthroscopic osteotomy. However, ventilation was difficult during anesthesia and impossible post-laryngeal mask insertion. Video laryngoscopy revealed a giant epiglottic cyst. Tracheal intubation under video laryngoscopy was eventually successful. Conclusion: In asymptomatic giant epiglottic cysts, preoperative anaesthetic assessment must be comprehensive, especially regarding the risk of a difficult airway. If the epiglottic cyst is discovered during anaesthesia, a difficult airway should be managed appropriately. Prompt use of video laryngoscopy in difficult airways increases successful intubation probability and appropriate ventilation tools may aid ventilation in cases of failed intubation. However, calling for help in all cases remains paramount.
