A Case of Lingual Thyroid Treated by Surgical Excision through Transcervical Approach / 대한이비인후과학회지

ABSTRACT

Lingual thyroid is the most common benign ectopic thyroid tissue but is a rare clinical entity. This developmental anomaly is due to the failure of descent of the gland anlage early in the course of embryogenesis. Patients may have symptoms of dysphagia due to obstruction or even hemorrhage. These symptoms can occur at any time from infancy through adulthood. The clinical findings, laboratory tests, and radiographic imaging studies employed in confirming the diagnosis and in planning appropriate treatment have been evaluated. The primary therapeutic goal is to restore thyroid function but surgical excision of the gland is reserved for more advanced cases of gland enlargement resulting in airway compromise, severe dysphagia that limits oral intake, or hemorrhage. We experienced a case of lingual thyroid that was successfully treated by transcervical approach and summarized the principles of current management for this condition.
