Abstract
We studied 15 cases of congenital cyst at the base of the tongue at Kanagawa Children's Medical Center from 1997 to 2010. The most frequent complaint (10 of 15 cases) was stridor. Nine cases were younger than 1 year old, and all of them exhibited stridor. Eleven cases were male, and four were female. In all cases, the outer part of the cyst wall was resected under direct laryngoscopy. The histopathological diagnosis of all cases was thyroglossal duct. Four cases relapsed and were resected again. Since then, they have not experienced further recurrence. Based on the results, resection of the outer part of the cyst wall under direct laryngoscopy is effective. When we examine patients who have difficulty breathing, a congenital cyst at the base of the tongue should be suspected.
