Details Descriptions About :: Bell’s Palsy

 Bell’s palsy is a disease of the facial nerve (cranial nerve VII) that produces unilateral or bilateral facial weakness. Onset is rapid. In 80% to 90% of patients, it subsides spontaneously and recovery is complete in 1 to 8 weeks. If recovery is partial, contractures may develop on the paralyzed side of the face. Bell’s palsy may recur on the same or opposite side of the face. Age Alert Although Bell’s palsy affects all age-groups, it occurs most commonly in people between ages 20 to 60. Recovery may be slower in elderly patients.

Pathophysiology Bell’s Palsy

Pathophysiology Bell’s palsy reflects an inflammatory reaction around the seventh cranial nerve, usually at the internal auditory meatus where the nerve leaves bony tissue. The characteristic unilateral or bilateral facial weakness results from the lack of appropriate neural stimulation to the muscle by the motor fibers of the facial nerve.
