A thoracotomy is an incision into the pleural space of the chest. It is performed by surgeons (or emergency physicians under certain circumstances) to gain access to the thoracic organs, most commonly the heart, the lungs, or the esophagus, or for access to the thoracic aorta or the anterior spine (the latter may be necessary to access tumors in the spine).

A thoracotomy is a major surgical procedure—it is the first step in many thoracic surgeries including lobectomy or pneumonectomy for lung cancer—and as such requires general anesthesia with endotracheal tube insertion and mechanical ventilation.

Thoracotomies are thought to be one of the most difficult surgical incisions to deal with post-operatively, because they are extremely painful and the pain can prevent the patient from breathing effectively, leading to atelectasis or pneumonia.

There are many different approaches to thoracotomy. The most common modalities of thoracotomy follow.

Median sternotomy provides wide access to the mediastinum and is the incision of choice for most open-heart surgery and access to the anterior mediastinum.

Posterolateral thoracotomy is an incision through an intercostal space on the back, and is often widened with rib spreaders. It is a very common approach for operations on the lung or posterior mediastinum, including the esophagus. When performed over the fifth intercostal space, it allows optimal access to the pulmonary hilum (pulmonary artery and pulmonary vein) and therefore is considered the approach of choice for pulmonary resection (pneumonectomy and lobectomy).
