Early UVFP Management Based on Neurological Evidences (UVFP = Unilateral Vocal Fold Paralysis)

Early UVFP Management Based on Neurological Evidences UVFP = Unilateral Vocal Fold Paralysis

The aim of this study is to understand how early intervention could impact reinnervation of the recurrent laryngeal nerve (which innervates the vocal cord), recovery of mobility of the paralyzed vocal cord and / or vocal recovery in the case of unilateral vocal fold paralysis. To achieve this goal we must therefore carry out a complete outcomes assessment of different intervention methods (voice therapy and injection laryngoplasty), which are offered to UVFP (unilateral vocal fold paralysis) patients in the early stage (< 3 months). Their respective impacts on the central and peripheral nervous system and on the voice quality will be assessed, taking into account factors related to the severity of the paralysis.

Inclusion Criteria:

- Unilateral paralysis in abduction of the vocal cords may be included in the study.

Exclusion Criteria:

• Wear a pacemaker or other implanted devices (prostheses ...).
• Wear metal clips, metal in the head, or an adjustable brain drain.
• Wear non-removable dental appliances (except fillings).
• Wear cardiac valve prostheses.
• Have worked the metals.
• Have a tattoo containing metal particles.
• Have implanted jewelry (e.g., piercing).
• Being prone to epileptic seizures.
• Take medications that alter cortical excitability.
• Have had a brain surgery.
• Suffer from intracranial hypertension.
• Be pregnant or breastfeeding recently.
• Present allergies that are incompatible with the experimental protocol.
• Have an abnormal hearing loss in view of their age, identified with tonal and / or vocal audiometry.
