Abstract

<p>A female neonate presented with inspiratory stridor and a persistent respiratory disorder after birth. Endotracheal intubation was performed because laryngoscopy revealed a mass lesion on the right side of her epiglottis. On the basis of findings of laryngofiberscopy, computed tomography, and magnetic resonance imaging, she was preoperatively diagnosed as having a congenital laryngeal cyst. She was referred to our department at the age of 24 days. We performed endoscopic marsupialization of the cyst by inserting a rigid endoscope through the oral cavity at the age of 28 days. The laryngeal cyst was located on the right arytenoid and aryepiglottic fold. Histologically, the cyst wall was lined with a stratified squamous epithelium. These findings were compatible with a ductal cyst. The patient’s postoperative course was satisfactory, and no evidence of recurrence or respiratory disorder was noted for 3 months after surgery. Because neonatal laryngeal cysts can cause severe respiratory disorders, neonates with laryngeal cysts require airway management and treatment as soon as possible. We recommend endoscopic marsupialization for the treatment of laryngeal cysts in neonates because of its minimal invasiveness, safety, and effectiveness.</p>
