Substernal goiter: A clinical review

Cervical Approach to Substernal Goiter: Do we Need Sternotomy? Cerrahpaşa Experience

“…Scintigraphy shows the activity of the thyroid tissue enlarging to the mediastinum, but absence of nuclear activity cannot exclude SG. MRI can be used as a diagnostic method, but shows no advantage over CT (2,6,7). In this study, none of the patients were evaluated with MR imaging.…”

“…Some other clinical studies showed that US was inefficient in diagnosing SG. In this study, US was generally done out of our clinic; any difference in results was considered normal given the differences in the experience of radiologists, and properties of US devices (2,3,6). Because of these heterogeneous US results, CT of the neck is accepted appropriate for patients with deviation findings on chest X-ray and for clinically symptomatic patients.…”

“…Sternotomy is performed in about 0 to 11% cases. This wide range may be explained by the absence of a common SG definition (6,7,(10)(11)(12)(13). Most of the SG studies have been published as series of author's self-experience, evaluation of their own surgical techniques and comparison of other studies on SG.…”

“…Neurovascularity generally originates in the cervical region, however, a limited number of studies have demonstrated that substernal thyroid tissue might originated in the mediastinum. While SGs usually extend into the anterior mediastinum (85-90%), 10-15% of them extend into the posterior mediastinum (2,5,6). Enlarged thyroid tissue may compress the trachea or esophagus and can cause symptoms such as dysphagia or dyspnea.…”
