Vocal Cord Paralysis/ Paresis

Causes, Symptoms, & Treatments for Vocal Cord Paralysis and Paresis

Location of the vocal cords - vocal cord paralysisVocal cords are a pair of tissue folds in the throat that vibrate to produce the sound of your voice.

Vocal cord paralysis occurs when nerve impulses to the voice box (larynx) are totally disrupted. If there is partial disruption of the nerve, then the condition is referred to as vocal cord paresis. The result, in either case, is a weakened voice that sounds breathy and tires easily.

Vocal cord paralysis not only prevents you from emitting normal vocal sounds but it can also create challenges while swallowing. Since vocal cords sit atop the trachea (windpipe), the folds close when ingesting food, drink, and mouth saliva. If either or both of the folds don’t close all the way, food, drink, or saliva will “go down the wrong pipe” and cause choking, coughing, and gasping.

 
 

Causes of Vocal Cord Paralysis

Vocal cord paralysis does not discriminate. It can affect males and females of any age, from birth to old age.

There are many causes of vocal cord paralysis:

  • Nerve damage during neck surgery
  • Complication from endotracheal intubation
  • Blunt neck or chest trauma
  • Tumors of the skull base, neck, and chest
  • Viral infections
  • Certain cancers

Symptoms of Vocal Cord Paralysis

In most cases, only one vocal cord is paralyzed.

Some symptoms of vocal cord paralysis can include:

  • A breathy or hoarse voice
  • Loss of vocal pitch
  • Choking, coughing, or gasping when ingesting food, drink or saliva
  • Frequent breaths while speaking
  • Speaking softly or weakly
  • Ineffective coughing
  • Frequent throat clearing

Treatment of Vocal Cord Paralysis

Unfortunately, we do not have treatments to make the injured nerve work better. But we can change the shape of or reposition the paralyzed vocal cord so that it works better with its normal partner (the unaffected vocal cord). Treatment for vocal cord paralysis/ paresis can include:

  • Voice therapy
  • Vocal cord augmentation with injections (gel or paste)
  • Vocal cord augmentation with implants

More on Injections to Treat Vocal Cord Paralysis/ Paresis

We commonly perform injections to treat vocal cord paralysis and paresis.

We recently performed an injection medialization laryngoplasty whereby gel was injected into the paralyzed vocal cord of a patient. The injection increased the volume of the paralyzed vocal cord so the functioning vocal cord could meet it to initiate vibration (and thus, sound).

In the “before” section of the video, you can hear the breathy, weak voice of the patient while he reads The Rainbow Passage.

In the “after” section of the video, the patient has his strong voice back and you witness the incredible success of injection medialization laryngoplasty performed by BergerHenry ENT.
