Mediastinotomy with exploration, drainage, removal of foreign body, or biopsy; transthoracic approach, including either transthoracic or median sternotomy

A mediastinotomy is a surgical procedure that involves accessing the mediastinum, the central compartment of the thoracic cavity, to perform various interventions such as exploration, drainage, removal of foreign bodies, or obtaining biopsies. This procedure can be approached through the chest wall, specifically using a transthoracic or median sternotomy technique. The transthoracic approach entails making an incision over the third costal cartilage on either the right or left side, allowing the surgeon to access the mediastinal space directly. The mediastinum is explored to identify any abnormalities, and if necessary, drainage of fluid collections is performed. Additionally, foreign bodies can be removed, and biopsies of the lung pleura and lymph nodes may be taken to aid in diagnosis. If the pleural space is entered during the procedure, a chest tube is typically placed to facilitate drainage and prevent complications. The incisions made during the procedure are then closed in layers to promote proper healing.
