Figure 6. Dissection of the cartilage of the left main bronchus via a right transcervical approach under pneumomediastinum. Dissection of the subaortic arch to the left tracheobronchial lymph nodes is performed along the ventral side of the left main bronchus reaching to the pulmonary artery to determine the caudal side of the lymph nodes in the subaortic arch to the left tracheobronchial region, which should be dissected. To enable the easy dissection of the left recurrent nerve lymph nodes, the left recurrent nerve is exposed via the right transcervical pneumomediastinal approach
