The mediastinum is the area in the middle of the chest between the lungs. A mediastinoscopy is a procedure to look at this area inside the chest. A tube with a light (mediastinoscope) is placed into the upper chest through a small opening (mediastinotomy). The light allows the doctor to see the area.

Description of the Procedure TOP
You will lie on the operating table on your back. Your skin will be cleaned with an antiseptic solution. A small cut will be made at the base of your neck, just above your breastbone. The muscles of your lower back will be separated. The mediastinoscope will be placed through the opening. The light from the mediastinoscope will help the doctor see the space between your lungs and heart. Tissue samples may be taken from the lymph nodes or other parts of your chest. The mediastinoscope will be removed and the opening will be closed with stitches. The wound will be covered with a dressing.
Immediately After the Procedure TOP
After the procedure, you will be taken to the recovery room. If all is well, your breathing tube will likely be removed. The tissue samples will be sent to the laboratory for testing.
