Laryngeal nerve injuries are one the most critical complications during thyroid and parathyroid surgery. Iatrogenic damages to the recurrent laryngeal nerve (RLN) are relevant in terms of clinical implications, economic costs, and for malpractice litigation. In order to minimize potential neural damages, a standardized surgical technique is mandatory. Intraoperatory neuromonitoring (IONM) of the RLN is an important adjunct to the traditional approach and is a reliable tool for neural mapping and in dissection and prognostication of postoperative neural function 4. Because of this, most of the iatrogenic damages are not related to direct transection, but they are visually undetectable. Notwithstanding the increasing use of IONM at this stage, there is still the need for prospective, randomized, well-powered, and well-designed trials in order to further validate (via evidence-based data) the role of IONM in thyroid surgery. The aim of this review is to provide a critical analysis of the scientific evidences on the clinical impact of IONM in thyroid surgery showing the unsolved problems and the future challenges.

Abstract
Laryngeal nerve injuries are one the most critical complications during thyroid and parathyroid surgery. Iatrogenic damages to the recurrent laryngeal nerve (RLN) are relevant in terms of clinical implications, economic costs, and for malpractice litigation. In order to minimize potential neural damages, a standardized surgical technique is mandatory. Intraoperatory neuromonitoring (IONM) of the RLN is an important adjunct to the traditional approach and is a reliable tool for neural mapping and in dissection and prognostication of postoperative neural function 4. Because of this, most of the iatrogenic damages are not related to direct transection, but they are visually undetectable. Notwithstanding the increasing use of IONM at this stage, there is still the need for prospective, randomized, well-powered, and well-designed trials in order to further validate (via evidence-based data) the role of IONM in thyroid surgery. The aim of this review is to provide a critical analysis of the scientific evidences on the clinical impact of IONM in thyroid surgery showing the unsolved problems and the future challenges.
