What is the appropriate acute management plan for an adult male with a 1‑day onset of right‑sided peripheral facial nerve palsy (Bell’s palsy) without other neurologic deficits?

Management Plan for Acute Right-Sided Bell's Palsy

Immediate Pharmacologic Treatment

Initiate oral prednisolone 50 mg once daily for 10 days within 72 hours of symptom onset to significantly improve facial nerve recovery, as this regimen increases complete recovery rates from 63.6% to 83% at 3 months. 1

• Start corticosteroids immediately—do not delay beyond 72 hours, as treatment initiated after this window provides no proven benefit. 1
• Alternative regimen: prednisone 60 mg once daily for 5 days followed by a 5-day taper (decreasing by 10 mg per day). 1, 2
• Do NOT prescribe antiviral monotherapy alone—it is ineffective and should never be used as sole treatment. 1, 3
• Optional: Consider adding valacyclovir 1 g three times daily for 7 days to the corticosteroid regimen, though the added benefit is modest (96.5% vs 89.7% complete recovery). 1, 4

Rationale for Corticosteroid Timing

The 72-hour window is critical because facial nerve inflammation and edema within the narrow temporal bone canal cause progressive nerve compression. 5 Early corticosteroid intervention reduces this inflammatory response before irreversible nerve damage occurs. 1

Eye Protection Protocol (Critical Priority)

Implement comprehensive eye protection immediately to prevent permanent corneal damage from lagophthalmos (incomplete eyelid closure). 1

Daytime Protection

• Apply lubricating ophthalmic drops (artificial tears) every 1-2 hours while awake. 1
• Prescribe sunglasses for outdoor use to protect against wind, dust, and foreign particles. 1

Nighttime Protection

• Apply ophthalmic ointment (such as dexpanthenol) at bedtime for sustained moisture retention. 1, 2
• Instruct on proper eye taping or patching technique with careful demonstration to avoid corneal abrasion. 1
• Consider moisture chambers using polyethylene covers for severe cases. 1

Red Flags Requiring Urgent Ophthalmology Referral

• Eye pain, vision changes, redness, discharge, foreign body sensation, or increasing irritation despite protection measures. 1
• Complete inability to close the eye (severe lagophthalmos). 1

Diagnostic Assessment

No routine laboratory testing or imaging is indicated for this typical presentation of acute unilateral peripheral facial palsy with onset <72 hours and no other neurologic deficits. 1, 4

Clinical Examination Priorities

• Document complete cranial nerve examination (CN V, VI, VIII, IX, X, XI, XII) to exclude stroke or skull base pathology—any additional cranial nerve involvement mandates immediate imaging. 1, 6
• Confirm forehead involvement (inability to raise right eyebrow) to distinguish peripheral from central lesion. 1, 6
• Assess severity using House-Brackmann grading: this patient appears Grade 3-4 (obvious asymmetry with right-sided weakness affecting smile and eyebrow raising). 5, 1
• Check for ear pain, taste disturbance, hyperacusis, or dry eye—common associated features. 5, 6

When Imaging IS Required

• Progressive weakness beyond 3 weeks. 1
• Bilateral facial weakness (extremely rare in Bell's palsy—suggests Lyme disease, sarcoidosis, or Guillain-Barré syndrome). 6, 7
• Recurrent episodes on the same side (requires MRI to exclude tumor). 7
• Other cranial nerve involvement. 1, 6
• No recovery at 3 months. 1

Patient Education and Counseling

• Expected recovery timeline: Most patients begin showing improvement within 2-3 weeks, with complete recovery typically occurring within 3-4 months. 1
• Prognosis: Approximately 70% of patients with complete paralysis recover fully within 6 months; those with incomplete paralysis (like this patient) have up to 94% complete recovery rates. 1
• Eye care is non-negotiable: Emphasize that corneal damage can occur rapidly and may be permanent without proper protection. 1

Follow-Up Schedule

Initial Follow-Up (1-2 Weeks)

• Assess early recovery trajectory and reinforce eye protection technique. 1
• Monitor for complications or new neurologic findings. 1

Mandatory Reassessment Points

• At 3 months: If facial recovery is incomplete, refer to facial nerve specialist for evaluation of reconstructive options. 1
• Immediate reassessment if new or worsening neurologic findings develop at any point. 1
• Urgent ophthalmology referral if ocular symptoms develop at any point. 1

Common Pitfalls to Avoid

• Delaying corticosteroid treatment beyond 72 hours—this eliminates the proven therapeutic benefit. 1
• Prescribing antivirals alone—this is ineffective and delays appropriate corticosteroid therapy. 1, 3
• Inadequate eye protection counseling—patients must understand the risk of permanent corneal damage. 1
• Failing to examine other cranial nerves—missing additional deficits can lead to misdiagnosis of stroke or tumor. 1, 6
• Ordering unnecessary imaging for typical presentations—this delays treatment without improving outcomes. 1
• Missing the 3-month reassessment window—this delays access to reconstructive options and psychological support for incomplete recovery. 1

Therapies NOT Recommended

• Physical therapy: No proven benefit over spontaneous recovery. 1
• Acupuncture: Poor quality evidence with indeterminate benefit-harm ratio. 1
• Surgical decompression: Rarely indicated except in specialized circumstances. 1

Special Considerations for This Patient

Given the patient's family history of stroke and cardiovascular disease, the clinical examination confirming forehead involvement and absence of other neurologic deficits is reassuring for peripheral (Bell's palsy) rather than central (stroke) etiology. 6 The rapid onset over 1 day and isolated facial nerve involvement without limb weakness, speech difficulties, or altered mental status further support Bell's palsy diagnosis. 6
