RESUMEN
The recurrent laryngeal nerve (RLN) injury is one of the most common complications of thyroidectomy,it causes vocal cord paralysis and seriously affects the quality of patients'life post operation.Intermittent intraoperative neuromonitoring (I-IONM) is found to quickly locate the RLN during operation,indentify anatomic variation,assess the neurological function and prognosis,effectively reduce and prevent the RLN injury.Despite that,I-IONM can only detect the RLN after injury when assessing the integrity of RLN in the short period of nerve stimulation.In order to overcome the limitations of Ⅰ-IONM,the continuous intraoperative nerve monitoring (C-IONM) was developed.Here a brief review on the research and progress of C-IONM in thyroid surgery was presented.
