Unilateral Vocal Cord Paralysis (UVCP)
What Is Unilateral Vocal Cord Paralysis?
Vocal cords vibrate to make sound. Vocal cords also close when you swallow. They protect your airway from food and saliva going into your lungs. When vocal cords do not move, they are considered paralyzed.
There are two types of vocal cord paralysis:
1. Both vocal cords do not move, called bilateral vocal cord paralysis (BVCP)
2. Only one vocal cord does not move, called unilateral vocal cord paralysis (UVCP)
Even though the two are related, the causes and management for each condition are different.
