Computed Tomography Findings Affecting the Decision of Sternotomy in Substernal Goiter

ObjectivesAlthough thyroidectomy is completed with a cervical incision in most patients with substernal goiter (SG), sternotomies may be required occasionally. The purpose of this study is to examine computed tomography (CT) findings that may predict the need for sternotomy in SG surgery.MethodsNeck-thoracic CT images of patients who underwent total thyroidectomy with the diagnosis of SG between 2013 and 2022 were retrospectively examined. The patients (n=41) were divided into two groups: sternotomies (n=6) and cervical (n=35). Preoperative pathological data, CT findings, and postoperative complications of the patients were recorded.ResultsThe total thyroid volume of the sternotomy group (280.75±127.01 mm3) was significantly greater than that of the cervical group (155.38±74.18 mm3) (p=0.015). The retrosternal thyroid volume (mm3), thyroid craniocaudal, and anterior-posterior dimensions (mm) were significantly greater in the sternotomy group (p=0.001, p
