Bell's Palsy

📋Overview

Known medically as idiopathic facial nerve palsy, this condition involves acute dysfunction of the seventh cranial nerve, which regulates facial movement and expression. It typically results in unilateral facial drooping that develops rapidly, often without a currently identifiable cause after clinical evaluation.

This form of paralysis is considered a peripheral nerve disorder and is clinically distinct from facial weakness caused by central nervous system events, such as a stroke. It is also differentiated from facial paralysis linked to specific trauma, tumors, or infections that can be identified through diagnostic testing.
