Introduction:
Identifying the recurrent laryngeal nerve is the gold standard for reducing injury in thyroidectomy.
Objective:
To evaluate the usefulness of neuromonitoring in identifying the recurrent laryngeal nerve.
Methods:
This was a study of 259 recurrent laryngeal nerves at risk during thyroidectomy performed with neuromonitoring (group A: 129 nerves) and without neuromonitoring (control group B: 130 nerves).
Results:
The percentage of visually unidentified nerves was 18% in group A and 20% in group B, with no statistical difference. From the moment of non-identification, identification with neuromonitoring was achieved in group A in 100% of cases. The difference was statistically significant. The positive and negative predictive value of neuromonitoring was 100%.
Conclusions:
Neuromonitoring helps to identify the recurrent laryngeal nerve and increases the security of the surgeon in the technique. It is advisable to perform neuromonitoring routinely in thyroid surgery.
