Crank-Shaped Sternotomy for Upper Mediastinal Lymph Node Dissection in Patients with Differentiated Thyroid Cancer.

We describe our modification of the reversed T-shaped sternotomy. The conventional technique consists of a limited upper sternotomy with transverse division of the sternum. Our modification involves shifting the transverse division lines one costal space between the right and left sides for perfect apposition of the divided upper and lower sternum. This technique can be used for patients with thyroid cancer and mediastinal lymph node metastasis and for those with a mediastinal tumor or certain cardiac disorders. [ABSTRACT FROM AUTHOR]
