Surgical injury of the recurrent laryngeal or vagus nerve is most common cause of unilateral vocal cord paralysis. However, cause remains idiopathic in number of cases (22%) significant6.
With the monitoring of CT EMGs as well as objective measurement of displacement of vocal fold across the test conditions, we demonstrated the validity of electrical pacing of paralyzed vocal fold with feedback from ipsilateral CT muscle in unilateral vocal cord paralysis.
The on-off movement of bilateral vocal folds was synchronized in the intact condition (Figure 5(a)), and such synchronization was disrupted by left RLN injury (Figure 5(b)), that is, no movement of left side vocal fold, indicating effective unilateral vocal cord paralysis. Importantly, when using the feedback signals of EMG envelopes from left (injured side) CT muscle, the movement of left (injured) vocal fold was restored and synchronized with the healthyside (Figure 5(c)).
