Normative data and interpretation of electromyogram signals of intraoperative neuromonitoring during thyroid surgery

Sangeun Lee, Bo Hae Kim

Abstract

Quantitative analysis of electromyogram (EMG) signals measured during thyroid surgery provides important information about the integrity of the nerve, and it allows to minimize the surgical related complication. Normative data in intraoperative neuromonitoring (IONM) during thyroid surgery provide reasonable evidence for determining setting value of IONM system, clearly predicting nerve injury during surgery, and suggesting indicators to predict reinnervation after the thyroid surgery. This article reviews the normative data of EMG of each nerve monitored during thyroid surgery and how to interpret events during thyroid surgery using the normative value of EMG.
