Intralingual Thyroglossal Duct Cyst Excision

INTRODUCTION Intralingual thyroglossal duct cyst is a rare presentation of this congenital anomaly, accounting for approximately 0.5% to 2% of cases of thyroglossal duct cysts. The most common presentations include airway obstruction and dysphagia. While the Sistrunk procedure remains the preferred method of excision in cases of cervical thyroglossal duct cyst, several studies have demonstrated the feasibility of transoral endoscopic excision in intralingual thyroglossal duct cyst without significant recurrence rates. In this article, we comprehensively describe our technique of endoscopic intralingual thyroglossal duct cyst excision. To date we have successfully managed six infants (range 1–5 months of age) using this technique.
