Vallecular cysts frequently cause difficult intubation due to poor glottic visualization during direct laryngoscopy. The appropriate way of airway management and predictive factors of difficult intubation are unknown. ⋯ Because children with vallecular cysts have a risk of difficult airway, we need to prepare for difficult airway management. The cyst-diameter to patient-height ratio could be useful as a predictor of difficult intubation.
