Recurrent substernal nodular goiter: incidence and management.

Overview

BACKGROUND: Surgery for recurrent multinodular goiter is associated with an increased risk of complications. When recurrence occurs in a substernal location, difficulties associated with surgical removal may be even more significant. METHODS: Information relating to indications for surgery, procedure performed, pathologic findings, and surgical complications was obtained from a prospective thyroid surgery database maintained in our unit for the past 39 years. RESULTS: During the study period 234 patients underwent operation for retrosternal recurrence of a nodular goiter. In the majority of cases (51%) the indication for surgery was the presence of compressive symptoms. In only four cases was a sternal split required to remove substernal recurrence. Complications occurred in 35 patients, including four permanent recurrent laryngeal nerve palsies. No patient had permanent hypoparathyroidism. CONCLUSIONS: Surgery for recurrent substernal goiter, although technically demanding, can be performed with a minimum of morbidity if appropriate attention is paid to anatomy and embryology. A sternal split is only rarely required.
