What are normal quantitative parameters of intraoperative neuromonitoring (IONM) in thyroid surgery?

Purpose: This study aimed at definition of normal quantitative parameters in intraoperative neuromonitoring during thyroid surgery. Only few and single center studies described quantitative data of intraoperative neuromonitoring. Definition of normal parameters in intraoperative neuromonitoring is believed to be a prerequisite for interpretation of results and intraoperative findings when using this method.
