Vocal Fold Paralysis and Laryngeal Reinnervation
Vocal fold paralysis is the loss of movement in one or both vocal folds, usually because the nerve supplying the muscles has been injured. The voice becomes weak or breathy, swallowing can become unsafe, and in bilateral cases breathing itself is affected.
Our approach
The central idea of this service is range. A paralysed vocal fold can be managed in several ways, and the right choice depends on the cause, the time since injury, the patient's age, and what the patient needs their voice to do. A clinic that offers only one technique tends to fit the patient to the technique. We prefer to keep the full range available and match the intervention to the patient.
That range runs from the temporary to the definitive. Injection augmentation can restore a usable voice quickly and buys time when recovery is still possible. Framework surgery repositions the fold for a lasting result. Laryngeal reinnervation reconnects a nerve supply, which can restore tone to the muscle rather than only repositioning the fold, and is considered particularly in younger patients with unilateral paralysis.
Who this is for
This service is for patients with a paralysed or weak vocal fold after nerve injury: often following thyroid, chest, or neck surgery, after a viral illness, or without an identified cause. Referring surgeons send patients with a new hoarse or breathy voice after an operation. Neurologists send patients whose swallowing has become unsafe. Some patients arrive years after the injury, having lived with a compromised voice, and are candidates for a definitive procedure.
Bilateral paralysis, where both folds are affected and breathing is the main concern, is a different and more urgent problem, managed with procedures that widen the airway.
What the procedure involves
For injection augmentation, see Office-Based Laryngology: it is an awake, in-clinic procedure. Framework surgery (medialisation laryngoplasty, at times with arytenoid adduction) is performed in theatre, repositioning the fold through a small neck incision while the patient's voice is checked during the operation. Laryngeal reinnervation connects a nearby nerve to the laryngeal muscle supply; the benefit appears gradually over months as the nerve grows, not immediately.
The choice among these is made together with the patient, after examination with stroboscopy and, where useful, laryngeal electromyography to assess the nerve.
Evidence and experience
Reinnervation and medialisation are established techniques with a substantial literature. Laryngeal reinnervation itself is performed by only a small number of surgeons worldwide. The director is among them, performs both unilateral and bilateral reinnervation, and teaches the technique as a faculty member of the Rouen Laryngeal Reinnervation Course. That depth of experience is what makes the full range of options, rather than a single default, available here.
What to expect afterwards
Injection augmentation gives an immediate but temporary improvement. Framework surgery gives a lasting result, with a recovery period and the usual surgical risks. Reinnervation asks for patience: months pass before the muscle regains tone, and the degree of recovery varies between patients. We are explicit that no option guarantees a normal voice, and that the aim is a reliable, usable voice matched to what the patient needs.
Frequently asked questions
Can a paralysed vocal fold recover on its own?
Some do, particularly in the first months after a nerve injury. This is why temporary injection augmentation is often used to restore a usable voice while spontaneous recovery is still possible. Whether to wait depends on the cause and the time elapsed.
What is laryngeal reinnervation?
Laryngeal reinnervation is an operation that connects a nearby nerve to the nerve supply of the laryngeal muscles, restoring tone to the paralysed vocal fold rather than only repositioning it. The benefit appears gradually over months as the nerve grows.
Is reinnervation better than injection or framework surgery?
No single option suits everyone. Injection works quickly but is temporary, framework surgery gives a lasting reposition, and reinnervation can restore muscle tone but requires patience. The right choice depends on the cause, the time since injury, the patient's age, and what the voice needs to do.
How long does recovery take after laryngeal reinnervation?
Months rather than weeks. The muscle regains tone gradually as the nerve grows, and the degree of recovery varies between patients.
