Vocal cord paralysis affects your voice box (larynx) in your throat. Your voice box has two vocal cords (also called vocal folds). These smooth muscles help you breathe, speak and swallow. When you talk or cough, air moves through your lungs and into your windpipe (trachea) and across your voice box. Your vocal cords vibrate as air passes through them. This is what produces the sound that’s shaped into your voice.
When you have unilateral vocal cord paralysis, one vocal cord doesn’t move (paralysis). Sometimes, the movement is very weak. It’s uncommon for vocal cord paralysis to affect both vocal cords. Bilateral vocal cord paralysis can be a life-threatening/altering condition that requires specialized care by an ear nose and throat (ENT) surgeon.
Symptoms of vocal cord paralysis include:
Some people have mild voice impairment with vocal cord paralysis. These people may be meeting their vocal needs without surgical intervention. Your surgeon may recommend surgery when symptoms are severe, life-disrupting or potentially life-threatening. Overall, if you’re struggling to meet the vocal demands of your work and life, medicalization laryngoplasty can be very helpful in restoring vocal function.

Some of the symptoms that existed before surgery may still be present for a short while after surgery as your voice box heals. You may have temporary neck soreness, hoarseness, vocal changes, and breathing and swallowing difficulties. Only in rare instances are these side effects permanent.
You’ll be discharged the same day or stay overnight in the hospital. You’ll need to rest your voice for a few days, but complete silence isn’t necessary.
