Recurrent Laryngeal Nerve Stimulator

Electrical stimulation of the recurrent laryngeal nerve is a safe and promising therapeutic approach with the potentiality to overcome the shortcomings of conventional surgical glottal enlargement. Although aberrant or synkinetic reinnervation is commonly considered an unfavorable condition, particularly for recovery of vocal fold movement, its presence is essential to ensure the effective clinical performance of laryngeal pacemakers. Thus, the effective selection of patients who can profit from laryngeal pacemakers implantation demands the implementation of new diagnostic tools based on tests capable of reliably detecting the presence of viable reinnervation on at least one vocal fold.
