Treatment for Dysphagia in Bell's Palsy
Patients with Bell's palsy who experience dysphagia should be treated with oral corticosteroids (prednisone 60-80mg daily for 7 days followed by a taper) within 72 hours of symptom onset, and should be referred to a facial nerve specialist if swallowing difficulties persist beyond 3 months. 1, 2
Initial Management
Corticosteroid Treatment
- Oral corticosteroids are the cornerstone of treatment for Bell's palsy and should be initiated within 72 hours of symptom onset 2
- Recommended regimen: Prednisone 60-80mg daily for 7 days followed by a 5-day taper 2, 3
- High-quality evidence shows corticosteroids significantly improve recovery rates from 70% to 94% 2
Antiviral Therapy
- May be considered as an optional adjunct to corticosteroids 2
- Options include:
- Valacyclovir (1g three times daily for 7 days) or
- Acyclovir (400mg five times daily for 10 days) 3
- Antiviral therapy alone is ineffective and not recommended 1, 3
Management of Dysphagia
Assessment
- Evaluate for oral incompetence, which is a common functional impairment in Bell's palsy 1
- Assess all phases of swallowing that may be affected:
- Oral preparatory phase
- Oral propulsive phase
- Pharyngeal phase 4
Specific Interventions for Dysphagia
Dietary Modifications:
- Modify food consistency based on swallowing ability 4
- Consider thickened liquids if thin liquids cause aspiration
Swallowing Techniques:
- Train patient in specific compensatory swallowing techniques 4
- Postural changes during eating (e.g., chin tuck) may improve swallowing safety
Referral Considerations:
Follow-up and Monitoring
Timeframe for Reassessment
- Most Bell's palsy patients show improvement within 3 weeks to 3 months 3, 6
- If dysphagia persists beyond 3 months, patient should be referred to a facial nerve specialist 1, 2
Specialist Referrals
- Facial nerve specialist: For persistent facial weakness or dysphagia after 3 months 1
- Neurologist: For new or worsening neurological findings at any point 2
- Speech-language pathologist: For ongoing dysphagia management and rehabilitation 5
Long-term Management
For Patients with Incomplete Recovery
- Consider reconstructive procedures for persistent oral incompetence 1
- Options may include static and dynamic facial slings 1
- Physical therapy may be beneficial for patients with more severe paralysis 3
Prognosis
- Overall prognosis is good, with more than two-thirds of patients experiencing complete spontaneous recovery 2, 3
- Early treatment with corticosteroids significantly improves outcomes 2
- Patients should be counseled about potential psychological impacts of facial paralysis, including difficulty expressing emotions and social interactions 1
Common Pitfalls to Avoid
- Delaying corticosteroid treatment beyond 72 hours of symptom onset
- Using antiviral therapy alone without corticosteroids
- Failing to provide adequate follow-up for patients with persistent symptoms
- Not addressing psychological aspects of facial paralysis
- Missing other causes of facial weakness by assuming Bell's palsy without proper evaluation
Remember that dysphagia in Bell's palsy is typically temporary, but proper management is essential to prevent complications such as dehydration, weight loss, and aspiration pneumonia while the condition resolves.
