Extended cervical mediastinoscopy.

Surgical exploration of subaortic and para-aortic lymph nodes has traditionally required the combination of standard cervical mediastinoscopy and left anterior mediastinotomy. Video-assisted thoracoscopic surgery is another technique that allows the exploration of these nodal stations. Extended cervical mediastinoscopy is a useful and safe technique for the assessment of para-aortic and subaortic nodal stations through the same incision of the standard cervical mediastinoscopy.
