We experienced a case of vallecular cyst causing airway obstruction in a neonate. A full-term 3136g male was born by a vaginal delivery following an uncomplicated pregnancy. Respiratory distress and cyanosis were presented 3 hours after birth, and he was transported to our institute. A large white cyst was found on the epiglottis while attempting intubation. It was difficult to identify the vocal cords because of the cyst, but he was successfully intubated. Computed tomography demonstrated a well-defined, round, low-density mass just posterior to the tongue base, without enhancement. Flexible laryngoscopy also revealed a white cyst which protruded from vallecula. With a pre-operative diagnosis of vallecular cyst, he underwent extirpation of the cyst using microlaryngoscopy. Histopathology showed squamous epithelium containing mucous glands in wall of the cyst. These findings are compatible with vallecular cyst. The post-operative course was uneventful. Follow-up laryngoscopic studies performed one week and 5 months after operation revealed no recurrence of the cyst and he showed good weight gain. Vallecular cyst should be considered in the differential diagnosis of neonates with dyspnea.
