Abstract

<p>Thyroglossal duct cyst is often discovered as a midline neck mass. We experienced a case of endolaryngeal extension of a laterally located thyroglossal duct cyst requiring extraction after tracheotomy. A 37-year-old male presented neck swelling that gradually increased for ten days without dyspnea. Endolaryngeal extension of the mass was found under fiberscope. Radiologic examination showed a clear and uniform mass which was located proximal to the hyoid bone. Extractive operation was performed. Tracheostomy was recommended to avoid technical difficulties of intubation before extraction. The cyst was not connected to the hyoid bone or pharyngeal wall. Pathological examination led to a diagnosis of thyroglossal duct cyst. Moderate postoperative laryngeal swelling occurred, but improved three days postoperative. A thyroglossal duct cyst should be considered in diagnosis of laterally located cervical cysts and in cases with airway obstruction.</p>
