Nonrecurrent Laryngeal Nerve in the Era of Intraoperative Nerve Monitoring

Figure 1

Full exposure of right nonrecurrent laryngeal nerve (non-RLN) from separation point (SP) on the vagus nerve to laryngeal entry. Electrophysiological signal is negative at distal stimulation point (d-V1) and positive at proximal stimulation point (p-V1) on the vagus nerve before separation of the inferior laryngeal nerve.
