Laryngeal Nerves Monitoring in Thyroid Surgery

In recent years, intraoperative neural monitoring (IONM) has gained widespread acceptance as an adjunct to the gold standard of visual nerve identification and it can be used identify both recurrent laryngeal (RLN) external branch superior (EBSLN). At present, three types IONM are performed: RLN intermittent neuromonitoring (i-IONM); continuous (c-IONM); EBSLN. i-IONM remains most employed method for confirming well mapping before is exposed in surgical field. allows prognostication postoperative function modifying plan – i.e., postponing treatment contralateral side (staged thyroidectomy) if during procedure loss signal occurs. On other hand, c-IONM detection severe combined events warning surgeon about impending injury, modification maneuvers with a potential preventing unilateral injury. EBSLN may at risk dissection thyroid vessels. Therefore, stimulation or without improve rate functional preservation voice following thyroidectomy.
