Living with Congenital laryngeal palsy

A condition also called congenital vocal cord paralysis, in which one or both vocal cords do not move well from birth.

Understanding Congenital laryngeal palsy

Congenital laryngeal palsy, also known as congenital vocal cord paralysis, is a condition in which one or both vocal cords do not move properly.

The cause of paralysis of both cords is often unknown. Sometimes it is linked to immature nerves or muscles, or nervous system conditions such as Arnold-Chiari malformation, cerebral palsy, hydrocephalus, spina bifida, low oxygen or bleeding. Birth trauma can cause temporary paralysis lasting 6 to 9 months. One-sided paralysis is usually of unknown cause. A flexible endoscope exam can diagnose it.
