Visualization Versus Intraoperative Neuromonitoring of the Recurrent Laryngeal Nerves in Thyroid Surgery

Some recent studies have shown that intraoperative neuromonitoring (IONM) can aid the recurrent laryngeal nerve (RLN) identification during thyroid surgery. However, the role of IONM in reducing the incidence of RLN injury rate and the value of this method in predicting postoperative RLN function remain controversial. Only a few published series represent level III of evidence and grade C of recommendation according to the evidence-based criteria (Sackett's classification, modified by Heinrich). Thus, the aim of this randomized clinical trial was to compare the impact of RLN visualization versus IONM on their morbidity following thyroid surgery.
