Results of Intraoperative Neuromonitoring in Thyroid Surgery and Preoperative Vocal Cord Paralysis

Abstract: Patients with pre-existing VCP revealed significantly reduced amplitude of ipsilateral VN and RLN, indicating retained nerve conductivity despite VC immobility. Preoperative laryngoscopy is therefore indispensable for reliable IONM and risk assessment, even in patients without voice abnormalities.

“…The INMSG definition of LOS with EMG change from initial satisfactory EMG to no or low (≤100 µV) response with stimulation at 1 to 2 mA in a dry field and no laryngeal twitch (12) has its limitation in pre-existing VCP with 14% of patients having intact EMG (38) and after intraoperative recovery of EMG amplitude after LOS (13). As recently shown nerve recovery after segmental or diffuse injury is diagnosed when amplitude increases from ≤100 µV back to >100 µV.…”

“…The introduction of neuromonitoring to thyroid surgery made it possible not only to easily identify the RLN but also to understand the physiology and mechanisms of RLN injury [1, 6, 13–16]. Since neuromonitoring of the RLN and the external branch of the superior laryngeal nerve was standardized, the use of this technique has become increasingly widespread [1, 17].…”
