What Researchers Did
French ENT specialists convened a multidisciplinary expert panel to develop evidence-graded clinical guidelines for the management of Bell palsy in adults.
What They Found
The guidelines recommend confirming Bell palsy with thorough ENT and neurological examination, gadolinium MRI within the first month, and ENMG for prognostic assessment. Corticosteroids at 1 mg/kg/day should start within 72 hours for 7-10 days. Adding antivirals is recommended only for severe early disease or Ramsay-Hunt syndrome; isolated antiviral therapy is not recommended. Importantly, the guidelines find no evidence that surgical facial nerve decompression improves outcomes; HBOT is not mentioned as a recommended treatment.
What This Means for Canadian Patients
For Canadians with Bell palsy, this guideline reinforces that early high-dose steroids remain the primary treatment. HBOT is not recommended for Bell palsy, and Canadians should be aware that it is not a supported indication.
Canadian Relevance
No direct Canadian connection identified. Bell palsy is a common condition; this guideline helps clarify that HBOT has no established role and should not be sought as a treatment.
Study Limitations
These guidelines are from France and based on studies primarily from European centres; some recommendations may not align precisely with Canadian ENT practice or Health Canada guidance.
