Background. The objective of this study was to identify the preoperative risk factors for patients in need of a sternotomy in the management of mediastinal goiters in order to provide better preoperative planning and patient consent.Methods. We analyzed 98 patients who underwent surgery for mediastinal goiters (goiters extending below the thoracic inlet 3 cm with the neck in hyperextension) between 1995 and 2008. Twelve (12.2%) of the patients required a sternotomy. The patients' features were analyzed by the surgical approach performed. Logistic regression analysis was used to study which variables were influencing the surgical strategy. The receiver operating characteristic (ROC) curves were designed when appropriate.Results. Terms such as retrosternal, substernal, intrathoracic, or mediastinal have been used to describe a goiter that extends beyond the thoracic inlet. Although suppression therapy by exogenous thyroxine can reduce the size of the gland by 20% to 30%, 1 the consensus is that the mediastinal goiter is a condition that requires surgical management. Literature reports often stress the need for surgical treatment in relation to compressive symptoms, potential airway compromise, and the possibility of an association with thyroid malignancy.
2-6The mediastinal thyroid can be usually managed through a cervical incision. 7 This approach has been shown to be sufficient in up to 97% of cases. 5 In patients in whom the gland cannot be safely removed through a cervical incision, thyroidectomy may require a thoracic approach to gain adequate exposure and to remove the gland while avoiding dangerous tractions. Unfortunately, there is no clear demarcation of the cases that require a combined approach, and the Correspondence to: G. Pata
