Use of King Vision videolaryngoscope in an unanticipated difficult airway in an adult patient with giant vallecular cyst, a case report.

Laryngeal cysts are largely asymptomatic and typically described in the context of incidental discovery on routine laryngoscopy. These cysts, in adults are even rarer and can have catastrophic consequences in an anaesthetized patient if airway management is inappropriate. We describe a case of difficult endotracheal intubation and the treatment of an adult patient with an asymptomatic, giant vallecular cyst that was discovered during rapid-sequence induction of general anesthesia in urgent surgery. In conclusion, vallecular cysts can cause extreme problems in securing the airway. It is important to avoid complications associated with repeated attempts at intubation, airway loss, or cyst rupture causing difficulty visualizing vocal cords and aspiration. The use of King Vision videolaryngoscope is a good alternative in these cases. Close attention to logistics and the immediate availability of an otolaryngologist is vital.
