Vocal cord paralysis is a medical condition that occurs when one or both vocal cords lose their ability to move normally. This paralysis can affect breathing, speaking, and even swallowing.

Types:

Unilateral paralysis: Affects one vocal cord.
Bilateral paralysis: Affects both vocal cords and is more serious as it may obstruct breathing.
