  • Title: Substernal goiters and sternotomy.
    Author: Cohen JP.
    Journal: Laryngoscope; 2009 Apr; 119(4):683-8. PubMed ID: 19160398.
    Abstract:
    OBJECTIVE: To determine what factors predispose patients with retrosternal goiters to median sternotomy. STUDY DESIGN: Retrospective review. METHODS: Analysis of a single surgeon experience with 113 substernal goiters operated upon during a 10-year period. RESULTS: 108 goiters were successfully removed through a cervical approach. Four patients required sternotomy, and it was concluded that one patient who did not receive sternotomy might have been better managed with sternotomy. Factors that led to sternotomy were malignancy, involvement of the posterior mediastinum, extensive substernal extension, and the presence of an ectopic nodule. The latter two were the most important factors. Revision surgery and tracheal compression did not influence the need for sternotomy. CONCLUSIONS: On the basis of preoperative imaging, it is possible to predict which patients with retrosternal goiters are likely to require median sternotomy. These factors are malignancy, extension into the posterior mediastinum, substernal extension inferior to the level of the aortic arch, and the lack of a solid attachment between the cervical and mediastinal components of the thyroid gland. Although previously reported, the latter factor has not received sufficient recognition in the management of retrosternal goiter.
