Management of substernal goitre

Abstract

Goitres of the thyroid gland whose major component resides substernally would appear to have a different presentation and management protocol than those goitres that reside mainly in the neck. These goitres, as opposed to their supraclavicular counterparts, usually present with symptoms referrable to compression of the trachea or esophagus. Even in those patients who are asymptomatic, a precise history may elicit pertinent findings. Furthermore, these goitres do not respond to suppression and require surgical removal. The trans-cervical approach is the most desirable, but the surgeon must be willing to enter the chest on that rare occasion. We reviewed the charts of 938 patients undergoing thyroid surgery who were registered in the Head and Neck Tumour Registry of the University of Toronto. Approximately 2.4% of patients had substernal goitres. Their history, pathology and ultimate surgical management will be discussed.
