Question

What happens if there is bilateral vagal denervation?

Option 1: Acute vocal cord paralysis
Option 2: Chronic vocal cord paralysis
Option 3: Increased vocal cord function
Option 4: No effect on vocal cords

Answer 1

Bilateral vagal denervation causes chronic vocal cord paralysis.

Step-by-step explanation:

Bilateral vagal denervation refers to the removal or damage of both vagus nerves, which are important for vocal cord function. Option 2: Chronic vocal cord paralysis is the correct answer. When both vagus nerves are denervated, it leads to a loss of innervation to the vocal cords, resulting in chronic vocal cord paralysis. This can cause difficulty with speech and swallowing.
