What is Vocal Cord Paralysis?

Vocal cord paralysis is a health condition where a person cannot control the movement of the muscles responsible for controlling the voice.

This health condition can make it difficult for a person to speak or, in worst cases, even breathe.

Vocal cord paralysis, also called vocal fold paralysis, can affect how the vocal cords work.

The inability of a person to control these muscles is often a side-effect of nerve damage.

During this health condition, mostly only one vocal cord doesn’t work properly. In some cases, this condition affects both the vocal cords.

Vocal cord paralysis can cause severe problems if left untreated, as breathing problems can occur.

Is vocal cord paralysis a common health condition?

Single vocal cord paralysis is more common than double vocal cord paralysis. As the name suggests, single vocal cord paralysis is when only one vocal cord is affected, and double vocal cord paralysis is when both vocal cords are affected.

This health condition does not discriminate in affecting men or women. However, it is most likely to be found in women than men.

What are the symptoms of vocal cord paralysis?

The symptoms of vocal cord paralysis can range from mild to severe; without proper treatment, it can be chronic.

Some of the symptoms of vocal cord paralysis include

  • Disturbed or squeaky voice
  • Hoarseness
  • Noisy breathing
  • Breathlessness
  • Vocal pitch loss
  • Choking
  • Coughing while swallowing food
  • Inability to speak loudly
  • Minimal gag reflux and
  • Frequent throat clearing

What can cause vocal cord paralysis?

Vocal cord paralysis is caused if the voice box is disrupted. A disrupted voice box can damage the muscles.  Despite not knowing what the exact cause of vocal cord paralysis is, some of the possible causes include

Injury to the vocal cord

Injury to the vocal cord can happen during surgery which can result in damage to the nerves that are present in the voice box.

Neck injury

A neck injury can damage the nerves that are present in the vocal cords. The nerves play an important role in the body, and any damage to them can leave a severe impact.


When a person has a stroke, it interacts with the blood flow in the brain and can cause damage to the part that sends signals to the voice box.


Tumours can be cancerous or non-cancerous that can grow around the muscles or nerves that control the function of the larynx, causing vocal cord paralysis.


Infections caused by various pathogens can cause diseases that can result in inflammation and directly damage the nerves causing paralysis in the vocal cord.

Neurological health conditions

Some neurological health conditions like sclerosis or Parkinson’s disease can damage the nerves and lead to vocal cord paralysis.

Some of the other risk factors that can cause vocal cord paralysis is undergoing surgery, specifically in the throat or chest and having a neurological condition.

How is vocal cord paralysis diagnosed?

A doctor or a healthcare provider will question the patient regarding their symptoms and lifestyle, and also listen to their voice and determine the problem.


This procedure is done when a doctor looks at the vocal cords with the help of a mirror or a thin tube known as an endoscope. This helps the doctor get insights as it contains a special camera that is present at the tip connecting the tube and giving a view of the vocal cord.

 Stroboscopy is a procedure performed to evaluate the vibration of the vocal cords. It assesses the movement of the vocal folds during sound production and produces a clear picture that is interpreted by the physician.

Laryngeal electromyography

Performing this test helps the doctor measure the electrical currents present in the voice box muscles with the help of small needles inserted into the vocal cord muscles through the neck of the skin.

This test is used to determine how well a person can recover.

A blood test or scan

A blood test can give a health care provider the necessary details of various infections or diseases present in the body.

With the help of blood tests and additional tests like x-ray, MRI scans or CT scans, a doctor can identify the cause of the paralysis.

Before Treatment in Vocal Cords

How is vocal cord paralysis treated?

Indication for Treatment : To improve your ability to speak and to swallow/prevent  airway compromise (difficulty breathing/aspiration / choking )

Treatment : Treatment of vocal cord paralysis depends on the cause, the severity of symptoms, and the time from the onset of symptoms.
Treatment may include Surgery:  Bulk injection (fat, collagen /teflon or some filler into the vocal cord)  Phono surgery (vocal cord repositioning)


The Vocal cord paralysis symptoms will not recover fully on their own. Sometimes surgical treatments are prescribed to improve a person’s ability to speak.

Sometimes during surgery, a vocal cord injection is injected to help treat the paralysis.

Laryngeal framework surgery is performed on a person to insert a voice box. The voice box helps to replace the damaged muscles and ease the symptoms of a person.

  • neuromuscular electrical stimulation
  • Laryngeal Reinnervation- Recurrent laryngeal nerve (RLN) reinnervation is a surgical option that helps manage hoarseness due to a one-sided vocal cord paralysis or immobility.

How to cope with vocal cord paralysis?

Vocal cord paralysis is a frustrating health condition that can affect a person’s everyday life. This condition can make it difficult for a person to communicate with other people.

A speech therapist can help a person develop the skills to improve communication.
