The mediastinum is the area in the middle of the chest between the lungs. A mediastinotomy is the creation of a small opening in the upper chest into the mediastinum. This opening allows the doctor to examine the area between and in front of the lungs.
This procedure is done to examine the lungs and chest. Your doctor might take tissue samples (biopsy). These samples are examined under a microscope to check for diseases like:
Mediastinotomy is also done to find out if lung cancer has spread.
