During thyroid surgery, the functional integrity of the recurrent laryngeal nerve (RLN) is not only threatened by direct nerve injury resulting from accidental transection, clipping or ligation. In fact, indirect trauma, e.g. traction and compression occurring repeatedly throughout gland dissection, contribute to long-term nerve impairment. In order to avoid RLN lesions and preserve nerve function the surgeon must adhere to and comply with a strict standardized intraoperative neuromonitoring (IONM) technique to preserve results, quality and safety.IONM should be a team work between the surgeon and the anesthesiologist
