- Complication of otitis media, mastoiditis, or cholesteatoma
- Guillain-Barré syndrome
- HIV, with or without opportunistic infection
- Sarcoidosis
- Sjögren syndrome
- Tumour
- Stroke, typically sparing the forehead and eyelid muscles
Management
- Corticosteroids (NNT 50 for mild-to-moderate, 8 for severe)
- No role for antivirals alone, but can consider adding in cases of severe Bell palsy
