Airway Management of Incidental Vallecular Cysts in Adults.

Vallecular cysts, largely asymptomatic in adults, are typically described only on incidental discovery during laryngoscopy, where they may present a challenge in airway management. The current literature is limited to case reports despite the potential for life-threatening complications. We describe management of such a case complicated by cyst rupture and intensive care unit admission. A literature review of eligible case reports was conducted, demonstrating an association between incidental vallecular cysts and difficult bag-mask ventilation and laryngoscopy with intraoperative otolaryngology consultation and intervention being common. Anesthetic management recommendations are thus presented, highlighting any conflicts with current difficult airway algorithms.
