5. Vocal cord paralysis in children: A new neurophysiological approach for diagnosis and functional prognosis

To establish the possibility to use the methodology of recording corticobulbar motor evoked potentials (CoMEPs) from cricothyroid muscles (CTHY) and vocal cord elicited by transcranial electrical stimulation (TES), as diagnostic tool for predicting function recovery in children with vocal fold immobility (VFI).We included six children (mean age: 4.7years; range: 2–9years) with diagnosis of cord immobility that underwent video-fibro-endoscopy procedure. Under general anaesthesia, we used TES by stimulation over C3/Cz or C4/Cz to elicit CoMEPs.
