Thyroidectomy by video assisted neck surgery (VANS) is associated with an elevated risk of recurrent laryngeal nerve injury, especially in the presence of unexpected anatomical abnormalities, such as non-recurrent inferior laryngeal nerve (NRILN), which can be exceedingly difficult to identify and preserve. To reduce the risk of nerve damage, computed tomography (CT) and ultrasonography are useful for preoperative diagnosis, but the number of cases in which anatomical abnormalities can be diagnosed by these modalities is limited. At our department, intraoperative neuromonitoring is performed during all thyroid surgeries, including VANS, in an attempt to reduce the risk of nerve injury.
