Abstract
Vallecular cysts are an uncommon cause of airway obstruction in children. It consists of glandular respiratory epithelium lined by squamous epithelium. The diagnosis of this rare entity is often difficult to establish due to its symptomatologic overlap with various pediatric conditions. Here, I report the first case of vallecular cyst in Qassim, Saudi Arabia diagnosed in an infant with upper airway symptoms and failure to thrive. He was diagnosed by Flexible fiberoptic laryngoscopy and underwent successful surgical excision. Postoperative course was uneventful, and a one-month follow-up revealed complete recovery.
