The Surgical Significance of Proper Nodes Along the Right Laryngeal Nerve Chain Situated in the Supreme Portion of the Thorax, Designated as “Top Nodes”
This paper presents the significance of “top nodes” as a relay point of afferent lymph flow from the mediastinum and the point of efferent flow to the cervical area. These nodes belong to the laryngeal nerve chain and are anatomically situated along the trachea, right subclavian artery and esophagus. By precise microscopic examination of all dissected lymph nodes, lymph was determined to principally flow from the superior mediastinal field to the cervical region in Iu cases. In Im cases, lymph flow was broadly distributed from the superior, middle and inferior mediastinal regions to the cervical and abdominal regions. In Ei cases, lymph tended to flow from the inferior mediastinal region to the abdominal region.
