Abstract

Ectopic thyroid is a rare congenital disease associated with compressive symptoms and hypothyroidism. It requires careful detection and well-planned surgical treatment. Our case is a typical ectopic lingual thyroid. We analyzed the etiology, symptoms, examinations and tests, diagnosis and surgery of the case in detail. Accurate diagnosis, adequate pre-surgical preparations and protection of blood supply of ectopic thyroid and surrounding structures during the surgery are key factors for successful treatment of ectopic thyroid.
