Vocal cord paralysis
Laryngeal nerve damage is injury to one or both of the nerves that are attached to the voice box.
Injury to the laryngeal nerves is uncommon.
However, it may occur from:
Injury to the left and right laryngeal nerves at the same time can be an urgent situation that can lead to difficulty breathing.
Treatment depends on the cause of the injury. In some instances, no treatment may be needed and the nerve may recover on its own. Voice therapy is useful in some cases.
If surgery is needed, the goal is to change the position of the paralyzed vocal cord to improve the voice. This can be done with:
If both the left and right nerves are damaged, a hole may need to be cut into the windpipe (tracheotomy) right away to allow breathing. This is followed by another surgery at a later date.
The outlook depends on the cause of the injury. In some cases, the nerve rapidly returns to normal. However, sometimes the damage is permanent.
