The Yawkey building entrance is now closed.

As of April 29, BMC’s Yawkey building doors are closed as an entrance. All patients and visitors on our main campus must enter the hospital via the Shapiro, Menino, or Moakley buildings, where they will be greeted by team members at a new centralized check-in desk. Learn more.

When performing a mediastinotomy, the surgeon makes a two-inch incision into the center of your chest cavity (the mediastinum) to evaluate and remove tumors in your heart and lung area. This procedure is often performed with a mediastinoscopy, in which the physician inserts a lighted instrument (mediastinoscope) to view the area and take a tissue sample. You will be required to fast in advance and refrain from driving following the procedure.
