Substernal or mediastinal goiters develop from the thyroid gland and progressively migrate into the thoracic cavity because of their weight, negative thoracic pressure, respiratory movements, and the shortness of the patient’s neck. They derive their blood supply from the superior and inferior thyroid arteries, which are surgically accessible through the neck. Substernal goiters should be distinguished from ectopic goiters arising from aberrant thyroid tissue; the blood supply for ectopic intrathoracic goiters does not depend only on cervical vessels. Therefore, the surgical management of purely intrathoracic goiters differs from that of substernal goiters [1].
