Dahle GO, Setså EJ, Svendsen OS, et al. - In this investigation, researchers assessed the impact of intraoperative electromyographic (EMG) changes on the contractility of the synchronous vocal cord through simultaneous use of continuous intraoperative neuromonitoring (C-IONM) and accelerometry for registration of actual vocal cord function at a given EMG amplitude change. By use of C-IONM, EMG was obtained following vagus nerve stimulation. Six recurrent laryngeal nerve (RLN) from four immature domestic pigs (Norwegian Landrace Norhybrid) with an approximate age of 3 months were studied. A decrease in EMG amplitude during traction injury to the RLN injury is closely linked to a parallel decrease in contractility of the vocal cord.
