Introduction: N. laryngeus reccurens injury is a serious complication in thyroid surgery. Nerve visualization is a procedure preventing its traumatization. The visualization with additional intraopertive neuromonitoring results in further reduction of the n. laryngeus reccurens injury rates. Aim: Verification of the intraoperative neuromonitoring effects on reduction of the n. laryngeus reccurens injury rates. Material, Methodology: 309 operated patients were included in the intraoperative neuromonitoring prospective study . A total of 295 patients were included in the study and intraoperative monitoring was performed per protocol. Results: Out of the total of 295 subjects, 1 patient sufferred from permanent paresis, ie. 0.33%, nerves at risk 0.2%. 6 subjects sufferred from transient pareses, i.e. 2.03%, nerves at risk 1.2%, with a prevailing 8-week recovery period of the ORL findings. Conclusion: Intraoperative neuromonitoring in thyroid surgery is yet another option for reduction of the n. laryngeus reccurens intraoperative injury rates.
