Is laryngeal paralysis progressive?
“Laryngeal paralysis” is a progressive disease that leads to suffocation. A severe cyanotic episode can lead to death. “Polyneuropathy” means multiple nerves are affected, most notably in the larynx (recurrent laryngeal nerves), but also in the esophagus and hind legs.
How do you know if you have a recurrent laryngeal nerve?
The Tubercle of Zuckerkandl marks the posterolateral aspect of the thyroid lobe and is most often found lateral to the recurrent laryngeal nerve. The tubercle can be found in 80% of thyroids and when found can lead directly to the recurrent laryngeal nerve, as 93% of the nerves are found medial to this tubercle.

What is laryngeal nerve damage?
Laryngeal nerve damage is injury to one or both of the nerves that are attached to the voice box. Laryngeal nerve damage can be caused by injury, tumors, surgery, or infection. Damage to the nerves of the larynx can cause hoarseness, difficulty in swallowing or breathing, or the loss of voice.
