Two cases of vallecular cyst: variable clinical presentation and management outcomes.

Vallecular cysts are rare congenital laryngeal lesions. Although histologically benign, they may cause significant upper airway obstruction, particularly in neonates, and can be life-threatening if not promptly managed. We report two cases of vallecular cysts in infants. The first case was a 54-day-old male infant presenting with respiratory distress, inspiratory stridor, and cyanotic episodes. Flexible fiberoptic laryngoscopy revealed a large vallecular cyst. The patient underwent urgent endoscopic excision. Histopathology confirmed a benign cyst lined by respiratory and squamous. The second case involved a 1-year-old male child presenting with chronic snoring, mouth breathing, and feeding difficulties. Imaging demonstrated a well-defined lesion at the base of the tongue. The patient underwent marsupialization of the cyst. Postoperatively, symptoms resolved completely. Vallecular cysts should be considered in infants with persistent stridor or upper airway symptoms. Surgical management is the definitive treatment and associated with excellent outcomes when performed promptly.
