Abstract

<p>In infants, even a small cyst frequently causes snoring, sleep apnea or stridor, and occasionally it can cause cyanosis or dyspnea because infants' upper respiratory tract is narrow and undeveloped. In this article, we present three cases of congenital cysts in infants with upper airway stenosis and a sucking disorder. The first case was of a laryngeal saccular cyst in a 5-month-old infant. The cyst was asymptomatic and was detected along with an upper respiratory infection. The cyst originated from the right laryngeal ventricle and covered the glottic chink. Laryngomicrosurgery was performed, and the whole cyst was transorally resected. The second case was also of a laryngeal cyst, in a 1-month-old infant, with stridor as the presenting symptom. The cyst was located around the right arytenoid and pyriform sinus and was completely resected by transoral surgery. The third case was of a cyst at the base of the tongue in a 1-month-old infant, which caused a sucking disorder and stridor. Microscopic marsupialization was performed because the cyst extended to the hyoid bone. In all three infants, postoperative recurrent nerve palsy did not occur and cyst recurrence was not observed. Although the ideal treatment for such cysts is complete resection, microscopic marsupialization is also appropriate dependent on the size of the cyst and its invasiveness.</p>
