To compare continuous (C-IONM) vs intermittent intraoperative neuromonitoring (I-IONM) in complex benign thyroid surgery, and to follow up patients with loss of signal (LOS) or unilateral vocal fold paralysis (UVFP). ⋯ Compared to I-IONM, C-IONM-application in complex benign thyroid surgery shows a significant reduction of transient UVFP and a non-significant trend in preventing permanent UVFP. In persistent UVFP with dysphonia, endolaryngeal phonomicrosurgery and transcervical laryngeal framework surgery are long-term effective treatment approaches to improve vocal function.
