How is the thymus gland removed with minimally invasive surgery?

Thymus lives: Behind the sternum or breast bone. Splitting it to access it or coronary arteries for bypass leaves a long scar. Big blood vessels live behind, the heart below. Accessing from above was done to acess nodes, or the left pleural space with thoracoscopic scopes is plausible, reserving conversion to open if bleeding ensues. There are many important vessels and nerves. I'd pick mediastinotomy still.

Three ways: 1) cervical: through a small incision in the neck. 2) thoracoscopy using a camera inserted between the ribs with 3-4 small incision 3) robotic assisted: much like thoracoscopy but with more advanced instruments. All three avoid having to split the sternum (breast bone) so people have less pain and recover faster. Most can go home the day after surgery.
