Nerves of the mediastinum.

Knowledge of the anatomy of the mediastinal nerves is essential for the evaluation and surgical treatment of most thoracic neoplasms. Thorough knowledge of the normal anatomy of the mediastinal nerves and of their variants cannot be overestimated because nerve trauma during nerve anatomy is also important because mediastinal or lung tumors can locally infiltrate those nerves either directly or through nodal metastases, making them generally unresectable.
