The condition is estimated to affect 5% of the general population. While the definition of substernal goiter varies in the medical literature, goiters usually are considered substernal (also referred to as mediastinal, intrathoracic, or retrosternal) when more than 50% of the thyroid parenchyma is located below the sternal notch. Such tumors have been a focus of interest for surgeons for over 150 years. Klein is credited with being the first to successfully remove a mediastinal goiter in 1820, although the earliest surgical description of mediastinal thyroid extension dates back to Haller in 1749. Today, substernal goiters are treated by a number of different surgical specialists, including thoracic, general, and head and neck surgeons. Goiters account for as many as 10% to 15% of space-occupying mediastinal lesions and are the most common of the superior mediastinal masses.
