Speaking Clearer: Updates on Vocal Cord Paralysis Treatment (Podcast)

Injections and surgical procedures are among the therapies for patients with early and late vocal cord paralysis

Vocal cord paralysis occurs when the nerve impulses to the larynx are interrupted, causing the vocal folds to become immobilized. There’s a high likelihood of recovery if the condition is diagnosed early and the recurrent laryngeal nerve is intact. The key is to refer patients to experts who can recommend the best treatment.

“If there’s a voice problem that isn’t easily fixed or identified in the clinic, have a low threshold to send [the patient] to a voice healthcare professional – a laryngologist, a speech and language pathologist who’s been trained in voice,” says William Tierney, MD, a laryngologist and head and neck surgeon at Cleveland Clinic. “It’s a relatively small community nationally, so there’s probably someone near where you practice that has access to videostroboscopy and can identify what’s going on and then get them to the people who do the specific procedures they need.”

In a recent episode of Cleveland Clinic’s Head and Neck Innovationspodcast, Dr. Tierney provides an update on vocal cord paralysis. He discusses:

  • Symptoms and causes of vocal cord paralysis
  • Treatment options, including injection augmentation and type 1 thyroplasty
  • Innovations within the field, such as laryngeal re-innervation and implant customization
  • The importance of including speech and language pathologists in developing a patient’s plan of care

Excerpt from the podcast

Podcast host Paul Bryson, MD, MBA: Do you want to elaborate on some of the causes of vocal cord paralysis and some of the predicaments that patients may undergo that then lead them to us?

Dr. Tierney: The iatrogenic causes of vocal cord paralysis, or vocal fold paralysis, are neck surgery, thoracic surgery and then anything that could potentially stretch the recurrent laryngeal nerve, which if you’ll remember from anatomy has sort of a tortuous path going down into the thorax on the left, looping under the ligament arteriosum and then coming back up to the larynx. And so anywhere along that line, you can have interruption or irritation of the nerve.


And so, the surgical procedures we think of are certainly any esophageal procedures, as the nerve runs in the tracheoesophageal groove on its way back up to the larynx. Thyroid surgery is one of the more common things that we have to think about in our world. Nodal laryngology, head and neck surgery. But then really any thoracic procedure has the potential to stretch the nerve.

We also see a certain amount of vocal fold paralysis or hypo-mobility, where we’re not sure necessarily that it’s paralyzed versus immobile, after some other common procedures like intubation. The thought being that the nerve can be put under some pressure by an endotracheal tube within the larynx and you can have a temporary or permanent immobility following an intubation, either short term or long term.

There are some other causes, but I think those are sort of the common ones that everybody should be aware of and look out for.
