sternotomy

Full Definition

Sternotomy is the standard surgical approach for accessing the heart and mediastinal structures, involving division of the sternum (breastbone) along its length. The most common type is median sternotomy, where the sternum is divided in the midline from the suprasternal notch to the xiphoid process. This approach provides excellent exposure for cardiac procedures including valve surgery, coronary bypass, and aortic surgery. The sternum is typically closed with wire sutures, and healing requires 6-8 weeks. Complications can include sternal wound infection, dehiscence, or malunion.
