Bell's Palsy

Bell's Palsy, the leading cause of unilateral facial paralysis, stems from likely viral reactivation that triggers nerve swelling within the narrow fallopian canal, resulting in axonal damage. As a diagnosis of exclusion, clinicians must first rule out stroke, tumors, or other neurological conditions. Standard acute management involves high-dose oral steroids administered within 72 hours to minimize nerve compression, often supplemented with antivirals and rigorous eye lubrication to prevent corneal injury. While 80% of patients achieve near-normal recovery, the remaining 20% may experience facial aberrant reinnervation syndrome, characterized by synkinesis, muscle hypertonicity, and spasms. These residual complications require specialized intervention from facial reanimation experts. Dr. Jacob Dey, a facial plastic surgeon at the Mayo Clinic, emphasizes that patients failing to show improvement within three weeks warrant further investigation to ensure no alternative diagnosis was overlooked.
