What Causes Bell's Palsy?
Reviewed: Dr. Gromatzky
1. Bell’s Palsy
In some cases, patients will find that their seventh cranial nerve becomes inflamed. This can cause swelling, and this can cause it to become tightly compressed in the narrow passage it passes through. This can then result in signals not being able to pass to and from the face and the brain as they usually would.
This then causes the patient to lose control over the muscles in their face in a condition known as Bell’s palsy. The condition can cause the patient to lose the ability to pull facial expressions. It can make eating difficult, while it can also affect taste, and saliva and tear production. The inflammation that causes this condition is often caused by various viral infections.
